It offers real-time visualization of tendons, ligaments, bursae, and joint recesses while enabling dynamic assessment and image-guided intervention. Building on the EURO-MUSCULUS/USPRM framework, this guideline presents a standardized, anatomy-based approach to diagnostic and interventional shoulder ultrasonography. Developed under the educational mission of the Ultrasound and Musculoskeletal/Neuromuscular Sonography Initiative in Taiwan - through its flagship programs Ultrasound Musculoskeletal Workshop in Taiwan (USMSIT) and Neuromuscular Ultrasound Workshop in Taiwan (NMUSIT) - the protocol integrates didactic instruction, live demonstration, and structured hands-on training to ensure reproducible and clinically relevant examinations. The guideline details systematic scanning of the long head of the biceps, subscapularis, acromioclavicular joint, supraspinatus, infraspinatus, teres minor, and posterior glenohumeral joint. It is also supplemented by tripartite visual documentation comprising cadaveric dissection, regional illustrations, and paired US images from both high-end and handheld devices. Characteristic sonographic findings for common shoulder pathologies - including biceps peritendinous effusion, acromioclavicular arthropathy, calcific tendinopathy, rotator cuff tears, and subacromial-subdeltoid bursitis - are described. In addition, practical pearls for US-guided interventions such as the long head of the biceps tendon, acromioclavicular joint, subdeltoid bursa, and posterior glenohumeral injections are provided. Emphasizing the principle of \"diagnosis ahead of intervention,\" this guideline bridges educational precision and procedural application-fostering consistent training as well as safer and more effective management of shoulder disorders. Its standardized image - anatomy framework further facilitates integration into artificial intelligence - assisted systems for automated view recognition and measurement. Therefore, it aims to advance clinical, educational, and research endeavors in musculoskeletal ultrasonography.</p>","PeriodicalId":45466,"journal":{"name":"Journal of Medical Ultrasound","volume":"34 1","pages":"1-8"},"PeriodicalIF":0.8,"publicationDate":"2026-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13128079/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147821915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional Doppler indices, although widely used, are limited in sensitivity, reproducibility, and early detection. Advances in three-dimensional power Doppler ultrasound (3D PD-US) and its vascular indices - vascularization index (VI), flow index (FI), and vascular FI (VFI) - offer semiquantitative evaluation of intraplacental microvascular function. Following Preferred Reporting Items for Systematic Reviews and Meta-analyses 2020 guidelines, this structured narrative synthesis reviewed literature from PubMed, Scopus, and EMBASE (2000-July 2025). A total of 1174 records were identified; after removing 328 duplicates, 846 titles and abstracts were screened, 137 full-text articles were assessed for eligibility, and 74 studies were included in the final synthesis assessing Doppler-based perfusion, biomarkers, or artificial intelligence (AI) integration in preeclampsia. Findings consistently demonstrate reduced VI, FI, and VFI in affected pregnancies, with FI showing the strongest reproducibility across cohorts. Emerging AI models trained on voxel-level Doppler data and angiogenic biomarkers such as placental growth factor and soluble fms-like tyrosine kinase-1 achieved high predictive accuracies (area under the curve 0.85-0.91) for early disease risk, although external validation remains limited. Integration of 3D PD-US indices with AI and biomarkers may enable early risk stratification, personalized monitoring, and informed timing of intervention. Heterogeneity in imaging protocols and the absence of meta-analytic pooling remain key limitations.

However, hand anomalies are often associated with other structural or genetic conditions, which makes accurate prenatal detection essential. This pictorial assay proposes a practical and standardized protocol for advanced fetal hand evaluation during the mid-trimester scan, including the assessment of digit number, structure, and position. Enhanced diagnostic precision can improve genetic counseling and inform decisions regarding further investigations, such as whole-genome sequencing, or considerations about pregnancy continuation.

In addition to conventional clinical risk factors, baseline echocardiographic evaluation also plays a critical role in the risk stratification of CTRCD, and numerous studies have demonstrated that baseline left ventricular ejection fraction, global longitudinal strain, and diastolic dysfunction are all predictive of the development of cardiotoxicity. Moreover, continuous surveillance of cardiac function throughout the course of cancer therapy is also paramount.
