About

This study aims at testing the discriminative validity of strain elastography in the normal and abnormal/pathological Supraspinatus tendon due to tendinopathy

Full description

The case-control trial will include 96 participants. 48 of them diagnosed with supraspinatus tendinopathy by MRI and 48 healthy subjects.

In this study the investigators will compare the outcome of tissue elasticity measured by sonoelastography, with MRI and conventional ultrasound.

Patients will be recruited through different radiology department and healthy volunteers will be recruited primarily through advertising in local newspapers and social media.
