Primary Aims:
To assess the value of sonoelastography in the evaluation of supraspinatus tendon abnormalities.
Secondary Aims:
1. To assess the association between SWE and grades of tendon abnormalities on MRI (the standard imaging in the evaluation of rotator cuff abnormalities). 2. To help in reaching shear wave elastography cutoff value to determine tendinopathy and tear.
Patients with shoulder pain either due to traumatic or non traumatic causes
Age > 18 year
History of operative intervention for rotator cuff tendons,
Signs of calcific tendinopathy on MRI or ultrasound (as calcification causes artifact on obtaining SWE results and the measured velocities were exceeding the velocity scale on our device),
Patients with general contraindications to MRI as patients with pacemakers
