POSITIVE CONTRAST SHOULDER ARTHROGRAPHY WITH IOPROMIDE AND DIATRIZOATE IN DOGS WITH OSTEOCHONDROSIS

Forty-one dogs (60 joints) with clinical and radiographic signs of shoulder osteochondrosis were randomized in a study to compare the diagnostic quality of iopromide (Ultravist, Schering AG) (n = 29) and meglumine-sodium diatrizoate (Urografin, Schering AG) (n = 31) in arthrography. The studies were performed using 1.5 to 4 ml of a solution of each contrast media at a concentration of 140 mg I/ml. Exposures were made within 5 minutes after intra-articular injection, Iopromide gave a significantly better arthrographic quality (P < 10(-6)).
