MRI of the shoulder will evaluate many bony and soft tissue structures including but not limited to scapula and rotator cuff tendons and muscles (supraspinatus, infraspinatus, teres minor, and subscapularis),
I am sure MRI will be helpful for you and for more suggestion you must consult with the expert doctor.
I want to say something about the MRI and with the help of MRI you can easily get the information about the scapula. In many cases MRI gives information about structures in the body that can't be seen as well with an X-ray, ultrasound, or CT scan. MRI can find changes in the structure of organs or other tissues. It also can find tissue damage or disease, such as infection or a tumor. So this is better than the X-ray or CT Scan.
