MRI - Arthrography
MR arthrography is highly sensitive for detecting intra-articular disorders (scapholunate and lunotriquetral dissociation, TFCC lesion, chondropathy).
MR arthrography is performed directly after conventional arthrography. By visualizing the third spatial plane, the dorsal and/or palmar rupture sites on the scapholunate and lunotriquetral ligaments can be precisely localized. MR arthrography is the method of choice at the TFCC to detect a rupture of the foveal lamina and should be performed before arthroscopy of the distal radioulnar joint. Another indication is the early assessment of focal cartilage damage.
MR arthrography competes with CT arthrography of the wrist. Both procedures provide similarly accurate results. The advantage of MR arthrography is that it is radiation-free; the disadvantage is the longer examination time and lower spatial resolution.
