Rotator cuff tears are the common problem in the shoulder. Fatty degeneration of muscles accompanied by tendon tears is an important prognostic factor. An accurate fat assessment is essential to set up treatment plan and to predict prognosis. However, there has been no standardized quantitative grading system, and the most widely used method for fatty infiltration is still disputed. We investigated the fat quantification using fat fraction map MR from the T2*-corrected in-phase and oppose-phase Volume Interpolated Breathhold Examination (VIBE) sequence in the patients with rotator cuff pathology on a 3-T clinical MRI scanner.
