The aim of this study was to evaluate the usefulness of the paramagnetic gadolinium-containing contrast agent, diluted 1:800, in evaluations of pathological changes in the canine elbow joint. The experiment was performed on 6 large breed dogs of both sexes with a body weight of 25 to 40 kg. Thoracic limb lameness and pain in the elbow joint area were observed in all patients. The animals were subjected to standard physical examinations, radiography and low-field magnetic resonance imaging scans with the use of a contrast agent. The Spin Echo T1 dorsal sequence as well as 3D SST1 transverse and XBONE T1 transverse sequences were highly effective in diagnosing osteochondritis dissecans (OCD) of the medial humeral condyle. Degenerative changes and the fragmented coronoid process (FCP) of the ulna were very well visualized by High Resolution Gradient Echo, XBONE T2 and Spin Echo T1 sequences in the sagittal plane. The administration of the gadolinium contrast agent, diluted 1:800, to the elbow joint cavity enhances the diagnostic value of magnetic resonance images in evaluations of medial compartment disease, in particular fragmentation of the medial coronoid process.
