  • 1. MUSCULOSKELETAL APPLICATIONSof SUPERSONIC SHEAR IMAGING (SSI) Pictorial Essay HUNG THIEN NGUYEN, HAI THANH PHAN MEDIC MEDICAL CENTER, HCMC, VIETNAM
  • 2. Purpose To apply the supersonic shear imaging (SSI) technique to musculoskeletal disorders in the situation of clinical utility is yet to be established.
  • 3. 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
  • 4. ResultsThe present pictorial essay includessupraspinatus, rotator cuff tears,Baker’s cyst,plantatis fasciitis,gout,synovitis, bursitissoft tissue lesions (inflammatory myositis, muscle tuberculosis),ganglion cyst

  • 36. 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.
