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.
