A New Promising Technique of 3D Isovoxel Imaging Using 3T MRI in the Wrist: Comparison with 3T MR Arthrography

known to be superior to conventional MR imaging for the evaluation of intrinsic ligament tears or triangular fibrocartilage complex (TFCC) tears (1-6). However, many of the studies that showed a better diagnostic performance of MRA than that of conventional MR imaging used a three-compartment injection method and they performed multiple MR sequences, and the total exam time was over 20 minutes (4, 5). When no communicational defects are visible after a single-compartment injection at the radiocarpal joint, some authors have said that at least injection into the distal radioulnar joint should be added to the diagnostic process (7). To the best of our knowledge, although many current studies have reported on 3D isovoxel MR imaging (ISO-MR) of the shoulder, knee and ankle, there has been no report J Korean Soc Radiol 2011;64:185-190
