Effects of different scanning azimuths of MRI on rotator cuff injury

Objective To investigate the detection effects of different scanning azimuth of magnetic resonance imaging on rotator cuff injury. Methods The MRI data of 117 patients with rotator cuff injury admitted in our hospital were retrospectively analyzed. The detection rates of rotator cuff injury was compared with different magnetic resonance imaging. Results ① Among the 117 patients, there were 79 cases of traumatic tendon injury, 43 cases of traumatic tendon injury, 26 cases of subscapular tendon injury, 20 cases of small round tendon injury, 14 cases of acromioclavicular capsule effusion, 11 cases of effusion, labial injury in 9 cases; ②the highest detection rate of double oblique coronal was 97.47% (77/79), and there was significant difference with oblique coronal, oblique sagittal and transverse axial (P 0.05). Conclusions MRI examination is an important means to diagnose the injury of the rotator cuff. It can clearly show the tendon and the soft tissue structure around the shoulder joint. The diagnosis of the tendon injury of the ascending apex is the first double transverse coronal scan, and the transverse axillary injury is preferred.
