Example illustrating the qualitative MR measurements. A 48-year-old woman with clinically suspected adhesive capsulitis (shoulder pain and limitation of movement). a Oblique 3D sagittal PD fat suppressed weighted images showing increased anterior capsule signal and thickness (yellow arrows). b Oblique coronal fat-sat T2-weighted image demonstrating axillary capsule thickening and abnormal increased signal intensity. There is increased thickness at the glenoid and humeral parts of the axillary joint capsule with high T2 signal intensity (thick yellow arrows). c Oblique coronal fat sat T2-weighted image at the level of coracoid process illustrating high signal intensity at the subcoracoid fat triangle (thick yellow arrows). d Oblique sagittal T1-weighted image demonstrating an obliterated subcoracoid fat triangle (thin yellow arrows). e Axial PD fat suppressed weighted image at the level of center of humeral head showing the angle of external rotation
