Evaluation of analytical grade of metrizamide for canine stifle arthrography.
The use of analytical grade of metrizamide as contrast material in canine stifle arthrography was evaluated in 27 stifle joints. A concentration of 280 mg of I/100 ml was prepared, and the material was injected at a rate of 0.3 ml/cm thickness of the lateral to medial measurement. Acceptable arthrograms were produced in 22 (81.5%) cases. The mediolateral radiographic view was useful in demonstrating the cranial and caudal cruciate ligaments, the infrapatellar fat pad, and the tendon of the long digital extensor muscle. The caudocranial radiographic view was useful in demonstrating the medial and lateral menisci, the articular surfaces of the femoral condyles, and the outline of the joint capsule. Radiographs made within 15 minutes after injection of the contrast medium were acceptable, thus setting this period as the limit for obtaining useful arthrograms. The double contrast technique was found to be of little value.
