Coronal T1 ( A, C ) and T2 ( B, D ) MR weighted images demonstrate muscle atrophy, discrete edema and fatty infiltration as radiological signs of subacute-chronic infraspinatus muscle denervation (white and black arrows)

Sagittal oblique ( A ) and axial ( B ) T2 MR weighted images show a bony prominence along the posterior glenoid rim and adjacent capsule-labral soft tissues (white arrows) and the infraspinatus muscle atrophy and fatty infiltration (black stars)

Fig. 3.

Axial ( A ), sagittal ( B ) shoulder TC and 3D reconstructions ( C ) show an eccentric curvilinear ossification along the posterior glenoid rim (at 9 o´clock) and adjacent capsule-labral soft tissues. The features are consistent with Bennett lesion of the shoulder

Schematic representation of the suprascapular nerve on its course through the suprascapular notch (blue arrow) and the spinoglenoid notch (green arrow), giving its two main muscular branches for the supraspinatus (orange) and the infraspinatus (yellow) muscles. Spine of scapula (1), acromion (2), coracoid process (3), posterior glenoid rim (4)

Fig. 5.

Greyscale ( A ) ultrasound image depicts the anatomy near the suprascapular notch (white arrows in A ). Color Doppler ( B ) ultrasound image highlights the suprascapular neurovascular bundle (white star) deep in location to the trapezius and supraspinatus muscles. Suprascapular vessels serve as a reference in Color Doppler to locate the respective suprascapular nerve, which, unless pathologically enlarged, is not observed in conventional images
