Abstract:

Objective:

To compare the effects of different MRI sequences scanning on diagnostic grading and fat infiltration score of rotator cuff injury.

Methods:

From January 2018 to January 2019, 100 patients diagnosed as rotator cuff injury clinically in our hospital were collected. The patients were imaged by different MRI combined sequences and scanning orientations to diagnose rotator cuff injury and to measure fat fraction.

Results:

The oblique coronal MRI had the highest detection rate on scapular sleeve injury, The oblique coronary SITR sequence showed the best for rotator cuff injury imaging (χ2=19.425, P<0.001) . The number of diagnosed cases of supraspinatus tendon injury (51 cases) , infraspinatus tendon (34 cases) , and subscapularis tendon (15 cases) imaged using oblique coronal MRI (SITR) were significantly higher than that using oblique coronal T1WI (12, 28, 6 cases) or T2WI (37, 19, 9 cases) . The preoperative fat infiltration score (2.58±0.23) in rotator cuff assess by oblique coronal MRI was significantly higher than that (1.72±0.17) during operation (t=7.320, P=0.002) .

Conclusions:

The oblique coronal SITR sequence is superior to other sequences in the diagnosis and grading of rotator cuff injury and fat infiltration score. It has a high diagnostic rate for rotator cuff injury and is worth popularizing.
