[Does intravenous gadolinium-DTPA administration have advantages in magnetic resonance imaging of acute injuries or chronic damage to the knee joint?].
79 patients with acute or chronic lesions of the knee were evaluated by MRI prior to and after application of Gd-DTPA. The MRI examination was performed by a 1.0 tesla imager with SE as well as FEDIF sequences. These MR studies were compared prior to and after intravenous Gd-DTPA application, focusing on the visibility and the definition of a possible lesion, and scored with a 3-point score. Statistic analysis and case analysis revealed that in patients with meniscus degeneration without a tear, Gd application yields no additional diagnostic information. However, in patients with meniscus tears Gd-DTPA significantly facilitates the definition of the lesion. Furthermore, Gd-DTPA makes differentiation possible between the synovial fluid and the synovial membrane. Whereas in cases with capsule or collateral ligament tears Gd-DTPA facilitates the documentation of the lesion, we found no advantage in using Gd-DPTA in patients with ACL tears. In patients with chondropathia patellae Gd-DTPA application supports the visualization of the secondary synovial reaction.
