Abstract

In the study of osteoarticular conditions, MRI makes a definite diagnostic improvement, even though some problems are still to be solved. Thus, on the basis of their arthrographic experience, the authors experimentally applied this technique to MRI, to assess the actual feasibility of MR arthrography. Forty-three patients were selected to undergo MR examinations after the intraarticular injection of 15-20 ml paramagnetic contrast agent (Gd-DTPA), with 0.25% saline solution. Before MR arthrography every patient underwent a baseline MR arthrography exam. Normal anatomy was better depicted with MR arthrography. In all cases, even small lesions and other structural changes missed at baseline MRI were demonstrated. Therefore, in agreement with previous arthrographic and CT arthrographic reports, we believe MR arthrography to be a simple technique improving MR diagnostic capabilities in selected cases.
