title: Intra-articular calcified bodies: detection by computed arthrotomography.
abstract: We used computed tomography (CT) in six cases to detect and localize intra-articular calcified bodies after double-contrast arthrography and pneumoarthrography . The cases consisted of one wrist, three ankles, and two knees. In one knee, one wrist, and two ankles, CT scanning after double-contrast arthrogram or air arthrogram accurately diagnosed and localized the intra-articular nature of the calcified bodies. In one knee and one ankle, the use of this technique accurately ruled out false-positive loose bodies suspected on the double-contrast arthrograms. Computed tomography after air arthrography or double-contrast arthrography is a simple and accurate technique to detect, localize, or exclude calcified bodies in the joints, and it is a useful adjunct when conventional tomography is inconclusive.
