MRI - Contrast agent
Unlike the often-unenhanced examinations, in our opinion it is essential to perform MRI of the hand with the use of contrast agent (intravenous, intra-articular).
Advantages of intravenous contrast agent are the following:
-
Injury sites of structures surrounded by synovium can be more accurately determined by contrast enhancement on fibrovascular repair tissue.
-
Synovial contrast enhancement allows differentiation between effusion and synovial proliferation.
-
The activity of an inflammatory systemic disease can be determined with the intensity of the contrast enhancement.
-
In Kienböck's disease and proximal osteonecrosis of scaphoid nonunion, the proximal necrotic zone can be differentiated from the hyperemic repair zone.
-
Tumorous lesions, such as neuromas, neurinomas or tenosynovial giant cell tumors, can be more easily differentiated based on their contrast enhancement.
