“…Just a few years later US was used to demonstrate synovitis and to evaluate result of the treatment in rheumatoid arthritis (RA) patients [Cooperberg et al 1978]. The applications of ultrasound to MSK conditions have continued to expand and it has become the primary modality of imaging for most of MSK conditions.…”

Abstract:The wide availability and recent improvement in technology coupled with portability, low cost and safety makes ultrasound the first choice imaging investigation for the evaluation of musculoskeletal diseases. Diagnostic use of ultrasound findings is greatly enhanced by knowledge of the clinical presentation. Conversely, ultrasound skills with its prerequisite anatomical knowledge make the clinical diagnosis more precise and reduce uncertainty in the choice of therapy. Therefore, it is essential for rheumatologists to acquire ultrasonography skills in order to improve patient care. Ultrasound examination provides an excellent opportunity for patient education and to explain the rationale for therapy. This review summarizes the indications for musculoskeletal ultrasound and describes its role in diagnosis, monitoring and prognosis.

“…In particular, here we focus on one such use, namely, determining finger positions using features extracted from US images of the human forearm. For a long time, US imaging has successfully been used as a diagnostic tool for hand musculoskeletal disorders such as, e.g., synovitis and rheumatoid arthritis [2]- [4], so US images should contain enough information to reconstruct the position, velocity and/or force exerted by the fingers. If this happens to be the case, a system enforcing this idea would have potential applications in, e.g., ergonomy and precise teleoperation and manipulation when operated by intact subjects, and could be a breakthrough if used by amputees, letting them control hand prostheses to a so-far unknown degree of precision.…”

Abstract-Medical ultrasound imaging is a well-known technique to gather live views of the interior of the human body. It is totally safe, it provides high spatial and temporal resolution, and it is nowadays available at any hospital. This suggests that it could be used as a human-computer interface. In this paper, we use ultrasound images of the human forearm to predict the finger positions, including thumb adduction and thumb rotation. Our experimental results show that there is a clear linear relationship between the features we extract from the images, and finger positions, expressed as angles at the metacarpo-phalangeal joints. The method is uniformly valid for all subjects considered. The unavoidable movements of the ultrasound probe with respect to the skin and of the skin with respect to the inner musculoskeletal structure are compensated for using the optical flow. Typical applications of this system range from teleoperated fine manipulation to finger stiffness estimation to ergonomy. If successfully applied to transradial amputees, it could be also used to reconstruct the imaginary limb, paving the way to, e.g., fine control of hand prostheses, treatment of neuropathic/phantom limb pain and visualization of the imaginary limb as a tool for the neuroscientist.Index Terms-Learning and adaptive systems, rehabilitation, ultrasound imaging.

“…But the majority of structures located peripherally to the articular cartilage can be eectively detected, including the articular capsule, ligaments, bursae, synovial recesses, and periarticular fat. Hence, typical signs of arthritis such as synovial thickening, joint eusion, structural changes of bursae, and fatty structures are easily detected by experienced operators who can diagnose and describe the disease, frequently avoiding unnecessary exposure to X-rays [4,5].…”

“…), who consensually classi®ed the hypervascularity as absent (no de®nite color spots inside the synovium) or present (visible color spots, either sparse or coalescing to form a sort of``synovial blush,'' expressing diuse hypervascularity of synovium). Typical sonographic signs of arthritis (synovial thickening and folding, joint eusion, cartilage thinning and erosion, and Baker's cysts) [4,5] were also considered. Disease activity was measured by evaluation of laboratory parameters (ESR, c-reactive protein, a 2 -globulins, sideremia, hemoglobinemia, and serum white cell count).…”

We compared power Doppler sonography to laboratory indices of disease activity in patients with knee arthritis to determine the clinical relevance of hypervascularity. Eight healthy volunteers and 22 patients with symptoms and signs of knee arthritis were studied. Presence or absence of hypervascularity, synovial thickening, effusion, and Baker's cysts were recorded. Disease activity was measured by erythrocyte sedimentation rate, c-reactive protein, alpha2-globulins, sideremia, hemoglobinemia, and serum white cell count. Various grades of synovial hyperemia were found in 12/22 cases. Patients with and without synovial hypervascularity showed statistically significant differences in age (P=0.017), erythrocyte sedimentation rate (ESR) (P = 0.039), hemoglobinemia (P = 0.009), and sideremia (P = 0.012). Power Doppler sonography is able to demonstrate synovial hyperemia, which is correlated with some laboratory indices of inflammation.
