Musculoskeletal Applications of Supersonic Shear Imaging (SSI)
MUSCULOSKELETAL APPLICATIONSof SUPERSONIC SHEAR IMAGING (SSI) Pictorial Essay HUNG THIEN NGUYEN, HAI THANH PHAN MEDIC MEDICAL CENTER, HCMC, VIETNAM
Purpose To apply the supersonic shear imaging (SSI) technique to musculoskeletal disorders in the situation of clinical utility is yet to be established.
Materials and Methods• A pictorial essay presentation.• Using conventional ultrasound and SSI technique with the linear probe (4-15MHz) of the Supersonic Imagine System, AiXplorer. The range we used was 0-180 kPa. Using a Qbox of 1 cm in diameter elasticity values were measured.• Some cases were compared to ARFI technology from Acuson S2000 Siemens
Calf Muscle Tuberculosis Histopathologic results= Some tubercular vesicles of muscle and soft tissues included caseum in the central and surrounding with degenerative cells, lymphocytes and Langhans giant cells.
Conclusions SSI technique can be used for various musculoskeletal applications. SSI is able to provide quantitative and local elastic information in real time. Further multicenter studies with the histopathological correlation need to be performed in order to establish the clinical utility of supersonic shear imaging.
