Radiographic anatomy and contrast arthrography of the radiocarpal joint in calves

Radiographic anatomy of the carpal joint was described in calves using dorsopalmer, mediolateral and flexed mediolateral projections. Positive and double contrast arthrography of the radiocarpal joint was done in these animals using Urographin (76%) and room air as positive and negative contrast agents. The positive contrast agent was used in the concentration of 19%, 25%, 38% and 76% and in volume ofl to 8 mL for various trials. Double contrast technique was done using 1 to 3 mL of undiluted Urographin alonguriih 15 to 25 cc air. Radiographs taken within 3 min of the injection of the contrast medium were of good quality. The articular structures were better visualized on using lower concentration (38%) of the contrast material. Optimum dose of the positive contrast agent for this joint was 3 to 4 mL. The double contrast technique had no advantage over the positive contrast arthrography except delineation of joint capsule thickness.
