Quantitative and Diffusion MR imaging as a New Method to Assess Partial-thickness Rotator Cuff Tear

Partial-thickness rotator cuff tear is usually depicted by a focal hyperintensity within a tear shown on fat-suppression T2 weighted magnetic resonance imaging (FS-T2WI). However, the hyperintensity is not always easily detected by FS-T2WI. To investigate the diagnostic performance of diffusion-weighted magnetic resonance imaging (DWI) for assessment of partial-thickness rotator cuff tears by means of lesion to muscle signal intensity ratios (L/M SIR ) as an alternative method.
