Digital subtraction wrist arthrography: use of double contrast technique as a supplement to single contrast arthrography.

A new technique using double contrast after digital subtraction wrist arthrography is presented. Results of the double contrast wrist arthrograms were essential to the diagnosis, confirmed the diagnosis, or salvaged an otherwise poor or nondiagnostic examination. It was found that intra-articular injection of air augments the information obtained during postarthrogram active motion studies under fluoroscopy. Double contrast wrist arthrography has proved valuable when the standard contrast arthrogram fails to yield diagnostic information.
