Research Background Musculoskeletal ultrasound, a rapidly evolving technique for ultrasound - based diagnosis and treatment of the musculoskeletal system, has seen expanding applications in visualizing peripheral nerves, muscles, tendons, joints, and skin thanks to improved ultrasound resolution. It offers advantages like convenience, cost - effectiveness, safety, real - time dynamics, continuous follow - up, and fast reporting. Given the high incidence and wide prevalence of rheumatic and immunological diseases, high - frequency ultrasound is gaining clinical attention. Consequently, learning and promoting musculoskeletal ultrasound is clinically valuable and necessary. However, this field faces challenges such as operator dependence, slow skill improvement and subjective differences in ultrasound diagnosis criteria and assessment methods for rheumatic diseases. The emergence of intelligent tools (AI) can address the urgent need for fast, accurate, and standardized ultrasound diagnosis. While AI has been used in multiple ultrasound sub - specialties, its application in musculoskeletal ultrasound is limited. This study aims to develop an AI - assisted musculoskeletal ultrasound examination system. It will help ultrasonographers by real - time segmenting structures like muscles, tendons, bone cortex, peripheral nerves, joint spaces, and blood vessels, extracting lesions (e.g., synovitis, tenosynovitis, bone erosion, cartilage destruction), and assessing lesion severity, thereby improving diagnostic accuracy and efficiency. Additionally, the system will shorten the learning cycle, enhance learning efficiency for musculoskeletal ultrasound, and accelerate its adoption in hospitals at all levels.
Research Objectives Primary Objective: To develop a musculoskeletal ultrasound AI - assisted examination system. This system will identify standard examination sections and continuous dynamic images of wrist and hand joints, mark specific structures in real - time, extract lesions, and assess their severity, enhancing examination efficiency and accuracy.
Secondary Objective: To help ultrasonographers shorten their learning period and master musculoskeletal ultrasound examination skills more quickly through the application of the AI - assisted system.

Started Jan 2021 (actual). Primary completion is estimated for May 2025, 52 months after the start.
Of 58 observational studies under Joint Diseases, half reached primary completion within 62 months of starting (the median), counting those still running; a quarter within 28 and three quarters within 153. This study's planned 52 months is below that.
