Abstract:
OBJECTIVE:To compare clinical application of 1.5 T MRI in acute rotator interval injury.
METHODS:Totally 160 patients with acute rotator cuff tear by clinical diagnosis were retrospectively analyzed by MRI examination and arthroscopy from March 2016 to February 2019, including 122 males and 38 females, aged from 22 to 71 years old with an average of (42.35±3.48) years old. Based on the results of arthroscopy as the gold standard, the shape and signal changes of rotator cuff, rotator interval, peripheral bursa, bone and soft tissue were observed by MRI on axial, oblique coronal and oblique sagittal imagese.
RESULTS:The direct MRI signs of acute rotator interval injury displayed thickening, diminution, distortion, interruption of the coracohumeral ligament and superior glenohumeral ligament complex with highsignal intensity on fat-suppression by proton weighted sequence. The indirect MRI signs displayed rotator cuff, peripheral bone and soft tissue injury. The consistency of the results between the two methods was quite satisfactory (Kappa=0.85), and the concordance rate of the two methods has statistically significant (
CONCLUSION:MRI could clearly display acute rotator interval, and could accurately diagnose acute rotator interval injury, which provide more accurate imaging basis for clinical diagnosis and treatment.
