In the United Kingdom, approximately one-third of the population suffers from musculoskeletal disorders, underscoring the need for effective diagnostic and management strategies. Musculoskeletal ultrasound imaging emerges as a preferred diagnostic modality, offering a balance between technical capabilities and cost-effectiveness, owing to its non-invasive nature, portability and lack of radiation exposure. However, the operator-dependent nature of musculoskeletal ultrasound imaging necessitates specialised training for medical and healthcare professionals. The integration of musculoskeletal ultrasound imaging into traditional clinical examinations, known as ultrasound imaging-assisted clinical examination (UIACE), enhances traditional diagnostic processes by providing immediate visual feedback, facilitating a more accurate and comprehensive assessment of musculoskeletal conditions. This approach not only refines diagnosis in cases with ambiguous symptoms or overlapping signs but also significantly improves patient reassurance and management strategies. In addition, incorporating musculoskeletal ultrasound imaging into medical education through ultrasound imaging-assisted clinical examination offers students a dynamic, interactive learning experience, fostering a deeper understanding of clinical anatomy and examination skills. By advocating for its systematic inclusion in the undergraduate medical curriculum, the study highlights the potential to enhance the competence and confidence of future professionals in utilising ultrasound imaging, ultimately improving patient outcomes in musculoskeletal care.</p>","PeriodicalId":23440,"journal":{"name":"Ultrasound","volume":" ","pages":"1742271X241280911"},"PeriodicalIF":0.8,"publicationDate":"2024-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11563557/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142648089","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}
