The aim of our study was to compare the placental elasticity values between normal pregnancies and preeclamptic pregnancies and evaluate the utility of shear-wave elastography of the placenta as a predictor for preeclampsia in high-risk pregnancy. A prospective study was performed with 90 singleton high-risk pregnancies having any of the 7 risk factors for developing preeclampsia (primigravida, history of preeclampsia, family history of preeclampsia, history of pregestational diabetes, chronic hypertension, advanced maternal age [≥40 years], and body mass index ≥26 kg/m 2 ) were enrolled in the study. Shear-wave elastography was performed in all patients at 20 to 24 weeks' gestation and at 34 to 36 weeks' gestation, at 2 sites: center and edge of the placenta. The patients were divided into 2 groups: normal pregnancies (group A) or developed preeclampsia (group B). Women with posterior placentation, obstetric disorders other than preeclampsia, or multiple gestation were excluded from the study. Group comparisons were done using the χ2 test or Fisher exact test. Shear-wave elasticity values at 20 to 24 weeks' gestation for group B at the center of the placenta (21.73 vs 9.72 kPa) and at the edge of the placenta (21.6 kPa vs 10.15 kPa) were significantly higher than those for group A ( P < 0.05). Similar results were seen at 34 to 36 weeks' gestation. With a cutoff of 13.1 kPa, we attained sensitivity of 95.2%, specificity of 92.8% and diagnostic accuracy of 93.3% for predicting development of preeclampsia. Patients with preeclampsia have a significantly higher stiffness of the placenta. Shear-wave elastography is useful to evaluate placental function. Elastography can be used as a supplementary tool for prediction of preeclampsia.

High-frequency ultrasound is the imaging modality of choice for evaluating penile pathology because of its easy access, low cost, and patient tolerance ( The Penis, Diagnostic Ultrasound, second edtion . Boca Raton: CRC Press; 2007:957-978). This pictorial review will illustrate the sonographic features of emergent and nonemergent penile conditions such as penile fracture, spongial tear, urethral injury, various types of priapism, erectile dysfunction, penile abscess, and Mondor disease.

Fetal anomalies suspected on fetal ultrasound may cause significant stress for patients. Some findings resolve or have minimal clinical significance for the neonate. Our purpose is to evaluate fetal ultrasound accuracy and false-positive results and determine the clinical impact on maternal counseling. A retrospective review was performed on electronic medical records for women receiving prenatal care at Harbor-UCLA Medical Center who had abnormal findings on fetal ultrasounds between January 2015 and December 2018. Corresponding neonatal medical records were reviewed for the suspected condition(s). χ2 and Fisher exact tests were conducted to assess associations between fetal ultrasounds and neonatal outcomes. Two hundred eight mothers and 237 babies (including all 29 sets of twins) were included in the final analysis. Fetal ultrasounds were significantly associated with neonatal findings for the following conditions (sensitivity, specificity): anatomical disorder of extremities (0.72, 0.97), anatomical disorder of the face/skull/brain (0.67, 0.91), congenital anomaly of gastrointestinal tract (0.75, 0.98), congenital heart disease (0.75, 0.91), genetic disorder (0.72, 1.00), growth restriction (1.00, 0.85), kidney disorder (0.55, 0.98), and large for gestational age (0.80, 0.98). The highest false-positive rates occurred in congenital heart disease (65.4%), anatomical disorder of the face/skull/brain (64.3%), and growth restriction (54%). Fetal ultrasound highly correlates with neonatal findings for many congenital conditions. However, it can also be associated with a high false-positive rate for certain diagnoses; maternal counseling should include the limitations of ultrasound, including the potential for false-positive results.

Percutaneous core-needle biopsy (PCNB) plays a growing and essential role in many medical specialties. Proper and effective use of various PCNB devices requires basic understanding of how they function. Current literature lacks a detailed overview and illustration of needle function and design differences, a potentially valuable reference for users ranging from early trainees to experts who are less familiar with certain devices. This pictorial aims to provide such an overview, using diagrams and magnified photographs to illustrate the intricate components of these devices. Following a brief historical review of biopsy needle technology for context, we emphasize distinctions in design between 2 major classes of PCNB devices (side- and end-cutting devices), focusing on practical implications for how each device is most effectively used. We believe a nuanced understanding of biopsy device function sheds light on certain lingering ambiguities in biopsy practice, such as the optimal needle gauge in organ biopsy, the benefits and risks associated with coaxial technique, the impact of needle selection and technique on bleeding, and the risk of unsuccessful sampling. In a subsequent pictorial, we will draw on the concepts presented here to illustrate examples of biopsy needle failure and how unrecognized needle failure can be an important and often preventable cause of increased biopsy risk and lower tissue yield.

The right ventricular fetal tricuspid annular plane systolic excursion index (FTI) can be used to evaluate right ventricular systolic function. The purpose of this study was to establish the reference range of the FTI in normal fetuses and evaluate its diagnostic value in hypertensive disorders during pregnancy. In this prospective observational study, the right ventricular FTI was measured in 208 normal single-gestation fetuses between 20 and 40 weeks. With the increase in gestational age, the right ventricular FTI did not significantly fluctuate. With the increase in the severity of HDCP, the right ventricular FTI decreased gradually. Compared with the normal group, the low right ventricular FTI group had a higher incidence of premature delivery and emergency delivery due to continuous abnormal fetal heart monitoring, but there were no significant differences in low birth weight, new born Apgar score less than 7 in 5 minutes, or admission to the neonatal intensive care unit. The FTI of the right ventricle of normal fetuses is relatively constant at different gestational weeks. The right ventricular FTI can be used to evaluate fetal cardiac function changes in pregnant women with HDCP.

The purpose of this study was to compare the diagnostic performance of 4 different ultrasound-based risk scoring systems for thyroid nodules (TNs). This study consecutively included 256 patients (mean age: 43.98 ± 12.94 years, min-max: 18-89 years; 225 females, 31 males) with 266 TNs. Each nodule was evaluated and classified according to the American Thyroid Association (ATA), American College of Radiology (ACR), European Thyroid Association, and Korean Thyroid Imaging Reporting and Data System (ACR-TIRADS, EU-TIRADS, and K-TIRADS, respectively) before performing ultrasound-guided fine-needle aspiration biopsy. Pathological results were reported according to the Bethesda system. Outcomes of the 4 classification systems were compared with respect to Bethesda results. Twenty-eight (10.5%) nodules had malignant cytology results. Diagnostic performances of the scoring systems were comparable with similar area under the curve values according to the reference standards of category 5 of each scoring system. The sensitivity and specificity values of these guidelines were as follows: ACR-TIRADS, 60.7% and 95.4%; EU-TIRADS, 71.4% and 93.3%; ATA-2015, 71.4% and 93.3%; and K-TIRADS, 67.9% and 93.3%. The biopsy rate of malignant nodules was 57.1% for K-TIRADS and ATA, whereas this value was 46.4% for ACR and EU-TIRADS. ACR-TIRADS had the lowest unnecessary biopsy rate (141 of 238 benign nodules, 46%). The diagnostic performance of 4 risk stratification systems appears to be comparable, as shown by similar sensitivity, specificity, and area under the curve values. However, the ACR-TIRADS had slightly higher accuracy and necessitated fewer unnecessary biopsies for benign nodules.

OBJECTIVES: Sonoporation as a method of intracellular drug and gene delivery has not yet progressed to being used in vivo. The aim of this study was to prove the feasibility of sonoporation at a level practical for use in vivo by using a large amount of carbon dioxide micro-nano bubbles. METHODS: The carbon dioxide micro-nano bubbles and 100 mg of cisplatin were intra-arterially injected to the swine livers, and ultrasound irradiation was performed from the surface of the liver under laparotomy during the intra-arterial injection. After the intra-arterial injection, ultrasound-irradiated and nonirradiated liver tissues were immediately excised. Tissue platinum concentration was measured using inductively coupled plasma mass spectrometry. Liver tissue platinum concentrations were compared between the irradiated tissue and nonirradiated tissue using the Wilcoxon signed rank test. RESULTS: The mean (SD) liver tissue platinum concentration was 6.260*103 (2.070) ng/g in the irradiated liver tissue and 3.280*103 (0.430) ng/g in the nonirradiated liver tissue, showing significantly higher concentrations in the irradiated tissue ( P = 0.004). CONCLUSIONS: In conclusion, increasing the tissue concentration of administered cisplatin in the livers of living swine through the effect of sonoporation was possible in the presence of a large amount of micro-nano bubbles.

OBJECTIVES: The aim of study was to evaluate the diagnostic utility of the renal parenchyma elasticity with the shear wave elastography (SWE) and microvascularization with the superb microvascular imaging (SMI) technique before kidney biopsy and to predict the complication of hemorrhage before kidney biopsy. METHODS: A total of 75 patients were included in the prospective study. Before the biopsy, vascularity features of the kidney parenchyma in the area to be biopsied were assessed by SMI and parenchymal stiffness by SWE and were examined by 2 independent radiologists. RESULTS: A statistically significant difference was found in the SMI and SWE values between the groups with and without hematoma and hematuria when compared with the Student t test and Mann-Whitney U test ( P < 0.05). The SWE hardness cutoff value, which maximizes the prediction of the development of hematuria, was found to be 18.40 kPa, and the sensitivity and specificity values were 84.4% and 62.8%, respectively. In SMI vascularity index values, the cutoff value was found to be 0.247410800 kPa, and sensitivity and specificity values were 81.3% and 83.7%, respectively. The cutoff value of the SMI vascularity index values that maximized the prediction of hematoma development was 0.297009650, and the sensitivity and specificity values were 87% and 87%, respectively. CONCLUSIONS: We believe that evaluating and standardizing the microvascularization and elasticity of the kidney parenchyma before a percutaneous kidney biopsy will be potentially useful as a guiding method in the prediction of postbiopsy hemorrhage development.

This study aims to evaluate the role of shearwave elastography (SWE) and superb microvascular imaging (SMI) for preoperative prediction of axillary lymph node metastasis (ALNM) in patients with breast cancer. In a cohort of 214 women with breast cancer, B-Mode ultrasonography (US), SMIvascular-index (SMIvi), and SWE (E-mean, E-ratio) values were recorded before tru-cut biopsy. Axillary fine-needle aspiration biopsy (FNAB) and sentinel lymph node sampling results were collected. Imaging findings and histopathological data were statistically compared. Receiver operating characteristic curve analysis was used to evaluate diagnostic performance. Reverse stepwise logistical regression analysis was conducted. Although ALNM was negative in 111 cases, it was positive in 103 patients. Axillary lymph node metastasis (+) group had larger size ( P < 0.001), higher vascularization (SMIvi: 8.0 ± 6.0 versus 5.0 ± 4.3, P < 0.001), and higher elasticity value (E-mean: 129 ± 31 kPa versus 117.3 ± 40 kPa, P = 0.014). Axillary lymph node metastasis was observed statistically more frequently in Her-2 positive cases ( P = 0.005). There was no significant difference between other B-mode US findings ( P > 0.05), SMI Adler ( P = 0.878), and E-ratio ( P = 0.212). The most appropriate cutoff value for the prediction of ALNM was 23.5 mm for size, 3.8 for SMIvi, and 138.5 kPa for E-mean. The most sensitive (77%) method was the SMIvi measurement, while the most specific (86%) finding was Her-2 positivity. The combined model (being Her-2 positive, >23.5 cm, and >3.8 SMIvi) increased the specificity (78%), PPV (71%), and accuracy (68%). Although the increased size is a previously studied parameter in predicting the risk of ALNM, Her-2 and data obtained by SWE, and SMI can be used to assist conventional US.

Estimated fetal weight (EFW) is frequently used for clinical decision-making in obstetrics. The goals of this study were to determine the accuracy of EFW assessments by Leopold and ultrasound and to investigate any associations with maternal characteristics. Postgraduate years 1 and 2 obstetrics and gynecology resident physicians from Harbor-UCLA Medical Center from 2014 to 2020 performed EFW assessments on 10 preterm (<37 weeks' gestational age) fetuses by ultrasound biometry and 10 full-term (≥37 weeks' gestational age) fetuses by ultrasound biometry and Leopold maneuver. Assessments were included if the patients delivered within 2 weeks of the assessments. One thousand six hundred ninety-seven EFW assessments on 1183 patients performed by 33 residents were analyzed; 72.6% of sonographic full-term EFWs, 69% of Leopold full-term EFWs, and 61.5% of sonographic preterm EFWs were within 10% of the neonatal birth weight (BW). The lowest estimation error in our study occurred when actual BW was 3600 to 3700 g. After adjusting for BW, residents were found to have lower accuracy when the mother had a higher body mass index (BMI) for full-term estimation methods (Leopold and ultrasound, β = 0.13 and 0.12, P = 0.001 and 0.002, respectively). Maternal BMI was not related to estimation error for preterm fetuses ( β = 0.01, P = 0.75). Clinical and sonographic EFW assessments performed by obstetrics and gynecology junior residents are within 10% of neonatal BW much of the time. In our cohort, they tended to overestimate EFWs of lower-BW infants and underestimate EFWs of higher-BW infants. Accuracy of full-term EFW assessments seems to decrease with increasing maternal BMI.

The location of the lateral femoral cutaneous nerve (LFCN) makes it susceptible to injury with trauma, external compression, and iatrogenic injury. The objectives of this study were to report the single-institution efficacy of LFCN visualization on ultrasound (US), define the clinical characteristics of patients with LFCN palsy, and describe sonographic appearances of LFCN abnormalities by pictorial review. A retrospective chart review of LFCN cases evaluated using US at a single institution was performed, documenting rate of visibility on US, mode of nerve injury, and US imaging findings. Nerve visibility rates on US were correlated with magnetic resonance imaging (MRI) when both modalities were used. Imaging findings were confirmed with clinical/surgical history and follow-up. Retrospective review found that 170 patients underwent US for LFCN evaluation in the last 10 years. Injury was associated with surgical intervention in 56% of cases, and perineural scarring was the most common pathology described using US. Lateral femoral cutaneous nerve was visible on US in 97% of cases; MRI visualized LFCN in 60%. Chart review showed US as an effective tool in evaluating LFCN pathology, with a higher visualization rate than MRI. Through pictorial review, the array of LFCN pathology sonographically detectable is demonstrated.

Initial findings of hand infections warrant a thorough treatment strategy depending on the progress of the infection. The decision for surgical treatment can be unclear. Searching to improve the quality of diagnostics, we reviewed the literature regarding the use of point-of-care ultrasound (PCUS) in hand infections and analyzed patients undergoing decision-making with PCUS. We searched PubMed, Scopus, Cochrane Register, and Google Scholar for the use of PCUS in therapy planning in infections of the hand. In addition, we screened our patients from July 1, 2020, to November 30, 2020, to validate the potential benefit of ultrasound examination in suspected hand infections. We evaluated initial clinical examinations versus blinded sonographic assessments in the context of correct decision to proceed with surgery or conservative treatment. Two thousand forty-eight studies within the topic were identified, but only 9 studies were found eligible to be included with a total of 88 patients. The studies illustrate that ultrasound can be performed on all patients, including children and pregnant women, and can be performed in a timely manner. In our retrospective analysis of 20 patients with suspected hand infection, the clinical and ultrasound assessment led to surgery in 13 cases. Of those 13 patients, 7 revealed intraoperative pus. By retrospective assessment of solely the ultrasound images, surgery would have been indicated in 9 cases, including all 7 cases with intraoperative pus. Clinical examination and ultrasound can help in detecting infections of the hand. Ultrasound examination, however, seems to yield a lower false-positive rate than clinical examination. Ultrasound could be a valuable addition to clinical examination.

Brain ultrasound in infants, although widely utilized, provides limited functional insights into the brain. Although color and power Doppler ultrasounds have allowed quantitative assessment of cerebral macrovascular flow dynamics, there is no standardized tool integrated into the current neurosonography protocol that allows cerebral microvascular flow assessment. The evaluation of anatomic and functional changes in cerebral microvessels is important, as microvascular alterations have been shown to precede macrovascular and tissue injury in a variety of neurologic diseases of infancy. In this regard, the cerebral microvascular imaging technique is a commercially available, advanced Doppler technique in which slow flow of cerebral microvessels can be detected via a static noise suppression algorithm. This article therefore shares the basic scan technique and clinical examples of the integrated use of microvascular imaging in neurosonography for infants, setting the stage for future clinical integration of the technique.

This study aims to assess the application value of transanal normal saline infusion-assisted multipath ultrasonography (TNSI-MU) in the diagnosis of T1/T2 rectal cancer (RC). All patients first received single-path 360-degree transrectal ultrasonography and then received 360-degree transrectal ultrasonography, transabdominal ultrasonography, or transvaginal ultrasonography after TNSI to determine the T stage. With surgical pathology as the criterion standard, the detection rates of T1/T2 RC lesions and the T-staging results of single-path 360-degree transrectal ultrasonography, TNSI-MU, and contrast-enhanced magnetic resonance imaging (MRI) were compared and analyzed. T1/T2 RC was surgically and pathologically confirmed in 52 patients. Single-path 360-degree transrectal ultrasonography had a lesion detection rate of 57.69% (30/52) and a T-staging accuracy of 80.0% (24/30), the sensitivity was 57.69%, and the specificity was 88.46%. Transanal normal saline infusion-assisted multipath ultrasonography had a lesion detection rate of 100%, and its T-staging accuracy was 84.62% (44/52), the sensitivity was 100%, and the specificity was 88.61%. Transanal normal saline infusion-assisted multipath ultrasonography had a significantly higher detection rate of T1/T2 RC lesions than single-path 360-degree transrectal ultrasonography ( P < 0.001), but the 2 methods had similar T-staging accuracy for T1/T2 RC (χ 2 = 0.286, P = 0.593). Contrast-enhanced MRI had a lesion detection rate of 100% and a T-staging accuracy of 40.38% (21/52), the sensitivity was 98.07%, and the specificity was 61.54%. Transanal normal saline infusion-assisted multipath ultrasonography had significantly higher diagnostic accuracy than contrast-enhanced MRI for T staging of T1/T2 RC ( P < 0.001), and the diagnostic results of the 2 methods were not consistent (κ = 0.151). Transanal normal saline infusion-assisted multipath ultrasonography outperformed single-path 360-degree transrectal ultrasonography in the detection rate of T1/T2 RC lesions and contrast-enhanced MRI in the staging accuracy for T1/T2 RC.

Transvaginal 4-D hysterosalpingo-contrast sonography (TV 4-D HyCoSy) plays an important role in the detection and diagnosis of clinical female infertility. The purposes of this study were to analyze the influencing factors of TV 4murD HyCoSy complicated with contrast agent reflux and to provide evidence for clinical diagnosis and treatment. Female patients diagnosed as infertility by transvaginal hysterosalpingography from January 2021 to December 2022 were included. The characteristics of patients with and without contrast agent reflux were evaluated. Pearson correlation and logistic regression were conducted to analyze the related factors affecting the occurrence of contrast reflux. A total of 416 patients undergoing TV 4-D HyCoSy were included, and the incidence of contrast agent reflux in patients undergoing TV 4-D HyCoSy was 38.94%. Pearson correlation analysis results indicated that history of uterine cavity operation ( r = 0.556), adenomyosis of uterus ( r = 0.584), examination on less than 5 days after menstruation ( r = 0.602), endometrial thickness ( r = 0.566), and endometrial polyps ( r = 0.575) are all correlated with contrast agent reflux in patients undergoing 4-D HyCoSy (all P < 0.05). Logistic regression analysis showed that history of uterine cavity operation (odds ratio [OR], 1.109; 95% confidence interval [CI], 1.012-1.872), adenomyosis of uterus (OR, 2.026; 95% CI, 1.864-2.425), examination on less than 5 days after menstruation (OR, 2.465; 95% CI, 2.118-2.851), endometrial thickness less than 6 mm (OR, 2.866; 95% CI, 2.095-2.957), and endometrial polyps (OR, 1.587; 95% CI, 1.137-1.744) were the influencing factors of contrast agent reflux in patients undergoing (all P < 0.05). The incidence of contrast agent reflux in TV 4-D HyCoSy is high, and there are many influencing factors. Clinical medical workers should take early measures based on these influencing factors to reduce the contrast agent reflux.

Point-of-care ultrasound (POCUS) curriculum varies among countries. However, the length of training required for physicians is still under debate. We investigated the impact of different training methods: short hands-on courses (STS), long academic training sessions (LTS), or both (mixed training [MTS]), for POCUS daily use and self-reported confidence overall and specific to specific clinical situations. This was a descriptive study conducted over a 3-month period through a Web-based survey designed to assess the influence of different methods of POCUS training among physicians and residents on their daily practice. The survey was sent to 1212 emergency physicians with prior POCUS training; 515 answers (42%) could be analyzed. Participants in the STS group performed POCUS less frequently than physicians in the LTS or MTS group. Daily use in the STS group was 51% versus 82% in the LTS group and 83% in the MTS group ( P < 0.01). The overall self-reported confidence in POCUS was lower in the STS group ( P < 0.01) in all studied clinical situations. There was no significant difference between LTS and MTS groups ( P > 0.05). Method of POCUS training significantly influenced POCUS daily use. Physicians who underwent long training sessions used POCUS more frequently in their routine practice and were significantly more confident in their ability to perform and interpret a POCUS examination.

Retrospective analysis was performed on the clinical information of 96 newborns with respiratory distress syndrome who were treated at our hospital between July 2015 and October 2017. The patients were split into the mild group (n = 55) and the severe group based on the findings of the chest x-ray examinations (n = 41). All neonates underwent an ultrasound examination at baseline, 12 hours after treatment and 24 hours after treatment of pulmonary surfactant (PS). Between the 2 groups, ultrasonographic characteristics and imaging scores were compared between infants with and without PS treatment. When compared with the severe group, the ultrasound score in the mild group was lower ( P < 0.05). Before treatment, there was no statistically significant difference in ultrasound score between the PS treatment group and the non-PS treatment group ( P > 0.05). At each time point after treatment, the ultrasonography score of the non-PS treatment group was greater than that of the PS treatment group ( P < 0.05). Neonatal respiratory distress syndrome severity may be accurately assessed using ultrasound technology. Furthermore, the results of ultrasonography examinations may serve as a significant marker for assessing and measuring the severity of newborn respiratory distress syndrome.

Thyroglossal duct cyst is the most common congenital neck mass, but the incidence of malignancy within a thyroglossal duct cyst is rare, estimated at 1%. Most cancers arising within thyroglossal duct cysts are incidentally detected after surgical excision. We present the preoperative radiologic findings of 8 patients with papillary thyroid cancer arising within a thyroglossal duct cyst, as evaluated on ultrasound, computed tomography, magnetic resonance imaging, and positron emission tomography scan.
