[Indications for CT and MR arthrography--recommendations of the Musculoskeletal Workgroup of the DRG].

The ongoing discussion about CT and MR arthrography is at least in part due to the lack of definite guidelines. The intention of the musculoskeletal workgroup of the DRG (Deutsche Röntgengesellschaft) was the establishment of recommendations for general guidance. After review of the recent literature, the indications for arthrographic examinations were discussed during a consensus meeting. Since the published data are insufficient and partially contradictory, no precise statements could be extracted from the literature. Therefore, the proposed recommendations are mainly based on expert opinions. In this review the main statements of the published literature are summarized and the recommendations of the musculoskeletal workgroup of the DRG are presented.
