Dogs presented to the Small Animal Hospital of Veterinary Medicine, University of Tehran were included in the present study if spinal or intervertebral disc involvement was suspected. Clinical signs were recorded as well as general information of the patient such as age, breed and sex. Sixty dogs were examined radiographically and two standard orthogonal lateral and ventrodorsal projections were taken from the suspected region. Then magnetic resonance imaging (MRI) was performed for all patients. Agreement between MRI and radiographic findings, comparison of sex and breed with diagnostic imaging grades, comparison between diagnostic imaging grades and mean age, recovery rate after surgery or medical treatment, effects of diagnostic imaging severity grades on surgical or medical referrals were evaluated statistically. There were no significant association between age, sex and breed and frequency of the intervertebral disk disease. Intervertebral disc involvements between L2-L3 and T13-L1 were estimated as the most frequent sites of involvements. Sensitivity and specificity of radiography were evaluated 90.0% and 46.0%, respectively, by considering the MRI as a gold standard modality. There was a significant association between severity of disease in the MRI with referral to surgery and medical treatment. The recovery rate after surgery was significantly higher than medical treatment. These results can be used as a foundation for other studies with more focuses on details of injury and larger group of patients.
