PURPOSE: This study aimed to evaluate an innovative anterolateral approach using portable ultrasound, comparing the accuracy and safety of portable ultrasound-guided, conventional ultrasound-guided, and landmark-based blind injection techniques. METHODS: In this single-centre, prospective, randomised controlled trial, 117 patients with hip pain were randomly assigned to three groups: landmark-based blind injection (n = 39), conventional ultrasound-guided injection (n = 39), and portable ultrasound-guided injection (n = 39). Each patient received a unilateral injection of 2.5 ml hyaluronic acid and 1 ml betamethasone via the anterolateral approach, using parameters optimized from previous research. Primary endpoints included success and accuracy rates, while secondary endpoints comprised post-injection visual analogue scale (VAS) pain scores, procedure time, puncture depth, and complications. RESULTS: The portable ultrasound group achieved 100% success and accuracy rates, comparable to the conventional ultrasound group, whereas the blind group showed lower success (87.2%) and accuracy (79.4%) rates. Post-injection VAS pain scores were significantly lower in the portable ultrasound group (1.95, SD 0.99) compared with the blind group (2.95, SD 1.61; p = 0.007) and similar to those in the conventional ultrasound group (2.41, SD 1.27; p = 0.337). Procedure times were comparable across all groups, and no significant differences in puncture depth were observed. Importantly, no injection-related complications were reported. CONCLUSION: Portable ultrasound-guided injections via the anterolateral approach demonstrate accuracy and safety comparable to conventional ultrasound-guided injections. Additionally, the portable device offers advantages in portability, reduced space requirements, and cost-effectiveness, thereby enhancing clinical utility in outpatient settings.

Contrast-enhanced ultrasound (CEUS) has become an important tool for the detection and characterization of solid renal lesions, complementing traditional B-mode US, which often struggles to distinguish between solid and cystic masses. CEUS enhances diagnostic accuracy by providing detailed vascularization information, helping to identify potentially malignant solid lesions and differentiate between pseudotumours and solid masses. Moreover, CEUS employs a contrast agent that is safe even for nephropathic patients and can be used without concern for kidney function, making it an advantageous method for renal imaging. In this narrative review, following the European Federation of Societies for Ultrasound in Medicine and Biology guidelines, the authors show its main indications: characterizing indeterminate renal lesions in patients with transplanted kidney, monitoring non-surgical lesions, diagnosing inflammatory-infectious renal pathologies, and assessing advanced renal lesions and masses in the surgical bed.

PURPOSE: Carotid plaque is a major risk factor for cerebral infarction. Ultrasonography (US) is extensively used for screening carotid plaque, but US images contain more noise than those of computed tomography and magnetic resonance imaging, and the edges of the plaque regions are unclear. In addition, B-mode echogenicity evaluation, which is important for plaque risk assessment, has challenges involving the subjectivity of the evaluator. Although previous studies on carotid plaque assessment have included plaque segmentation, most studies involved manual operations. In this study, we propose an automated scheme of plaque classification based on segmentation in carotid US images using the transformer approach, to resolve the issues of previous studies and to perform plaque echogenicity classification. METHODS: The B-mode video captured in the long-axis cross-section was converted to still images, and region extraction and echogenicity classification were performed using TransUNet. The results of the TransUNet output and US images were fed into the Vision Transformer (ViT) for classification into hypoechoic or isoechoic-hyperechoic plaques. RESULTS: The Dice index, which indicates the accuracy of plaque region extraction, was 0.592. The Dice indices by echogenicity were 0.200, 0.493, and 0.542 for the hypoechoic, isoechoic, and hyperechoic regions, respectively. The balanced accuracy, which indicates the classification accuracy, was 79.6%. The correct classification rate for high-risk hypoechoic plaques was 95.2%. CONCLUSION: These results suggest that the proposed method is useful for evaluating the echogenicity classification of carotid artery plaques.

PURPOSE: To investigate the clinical utility of a novel transperineal ultrasonographic (TUS) parameter, the TUS station, for assessing labour progression and predicting forceps delivery difficulty. METHODS: In this prospective cohort study, 384 TUS images from 144 participants who delivered vaginally between January 2019 and December 2021 were assessed for labour progression in a single tertiary perinatal center in Japan. Singleton cephalic pregnancies ≥ 37 weeks were included. The digital vaginal examination (DVE) findings, TUS station, and angle of progression (AoP), an ultrasound parameter commonly used for assessing labour progression, were obtained by individual obstetricians who were blinded to the results in all cases. The TUS station and DVE findings and AoP and DVE findings of the participants were compared. A second cohort requiring forceps delivery was analyzed to explore the relationship between TUS station and delivery difficulty. RESULTS: In the quantitative assessment of fetal head descent, the TUS station correlated with DVE findings. During the resting phase of labour, the TUS cut-off value for an easy forceps delivery was 2 cm, with a sensitivity of 85%; the maximum AUC value was 0.9 (95% confidence interval [CI]: 0.73-0.96). At the time of labour, the TUS cut-off value for an easy forceps delivery was 2.9 cm, with a sensitivity of 85%; the maximum AUC value was 0.8 (95% CI 0.65-0.96). CONCLUSION: The TUS station may serve as a valuable and objective parameter for consideration in decisions regarding forceps delivery.
