Arthrography in cats with non-ionic contrast agent ULTRAVIST 300

Abstract

Arthrography with nonionic contrast agents is a method of investigation of the joint space allowing routine observations of aseptic pathological condition localized at joint ends or synovial membrane. The biological material was represented by a uniform batch consists of 8 adult cats, two males and six females, European breed, with average body weight of 3.5 kg. Method of operation was the intra-articular injection of the contrast agent Ultravist 300 followed by x-ray exposure performed at 10, 15, 30 minutes at 1 hour and 2 hours after administration of the substance. Useful doses were determined according to the joint: for the shoulder joint 2.0-2.5 ml; for elbow joint 2.0-2.5 ml, for the stifle joint 0.5-3.0 ml. Machine working parameters ranged from 48-55 kV and 15-20 mAs, patient position and radiographic exposure was latero-lateral. Quality opacification in arthrography is reduced as you increase the injection interval, the optimal period being in the first 5 minutes. The contrast notional Ultravist 300 arthrography can be used in cats with high diagnostic value in joint diseases. Side reactions were minimal and showed no significant loss in patients.
