MSK MRI

The flexor carpi radialis brevis vel profundus extends from the distal radius to the capitate and base of the third and fourth metacarpals. It passes between the pronator quadratus and FCR muscles. Many accessory muscles have been described in the hand. Most are asymptomatic, but they can be a cause of compressive neuropathy or a palpable soft tissue mass. Detection can be difficult because the ..

Illustration of IB complete tear showed the detachment of both the fovea and the styloid insertions of the TFC. It involves both the foveal and the styloid insertions of the TFC and shows the irregular high signal intensity. Other signs may include altered morphology, focal synovitis, and fluid accumulation. The complete tear is typically associated with DRUJ instability. Theoretically, it may r..

Stage I • Bone marrow edema due to ischemic damage without morphological changes • Normal density of the lunate in radiography and attenuation at CT scan • Low signal intensity on T1-weighted images and usually hyperintense on T2-weighted fat-suppressed images. Stage II • Sclerosis of the lunate bone due to chronic ischemic damage • Increased density in radiography with preserved morphology • CT..
