Excessive intra-articular administration of gadolinium chelates during magnetic resonance (MR) arthrography results in decreased signal throughout the joint on MR images. A case with this condition during MR arthrography of the hip is described, and a possible solution when this problem occurs (ie, performing the MR imaging examination after a waiting period of several hours) is suggested.
