From: 7-T clinical MRI of the shoulder in patients with suspected lesions of the rotator cuff
Pathologic findings associated with shoulder pain at 7 T and 1.5 T, confirmed by arthroscopy. Coronal proton density (PD)-weighted fat-saturated images of the right shoulder of a 31 year-old male patient, showing a partial rupture of the supraspinatus tendon (arrows): the partial tear near to the footprint of the tendon is more distinct at 7 T (a) than at 1.5 T (b) because of higher tissue contrast. Axial PD-weighted fat-saturated images of the right shoulder of a 51-year-old female patient with irregularities and thinning of the humeral cartilage: due to higher image resolution, pathology can clearly be depicted at 7 T (c, arrows), but not at 1.5 T (d). Axial PD-weighted fat-saturated images of the left shoulder of a 58-year-old male patient with tendinopathy of the subscapularis tendon (circle): the better tissue contrast and higher image resolution at 7 T (e) depicts thickening and oedema of the tendon much better compared to 1.5 T (f)
