Objectives & aim of work:(1) To assess role of shear wave sono-elastography in the evaluation of supraspinatus tendon abnormalities. (2)To assess the association between shear wave velocities (SWV) measured by shear wave elastography (SWE) and grades of tendon abnormalities on MRI (as the gold standard imaging in the assessment of rotator cuff abnormalities). Background:Rotator cuff diseases are of the main causes of chronic shoulder pain.Diagnostic imaging is important to guide treatment decisions via the diagnosis and proper assessment of rotator cuff abnormalities. Magnetic resonance imaging considered the gold standard imaging for assessment of rotator cuff abnormalities. Ultrasonography is an inexpensive, non invasive and reliable tool for assessment of rotator cuff abnormalities with comparable results to MRI.Sonoelastography is a new ultrasound technique whichprovide qualitative as well as quantitative assessment of quality of tissues. So, it can help in detection of tendon abnormalities through alteration in the tissue composition before alteration in tendon echogenicity on conventional US. SWE is considered objectivein comparison to strain elastography as no compression applied to the examined tissues, provides direct quantitative measurement of tissue elasticity as well as the advantage of imaging deeper tissue
