Summary Today Computer Tomography (CT) and Magnetic Resonance Imaging (MRI) are commonly used to evaluate acute intervertebral disk extrusion in condrodystrophic dogs. The purpose of this study was to evaluate the sensitivity and the real utility of CT an MRI in determining level and lateralization of acute thoracolumbar intervertebral disk extrusion in comparison with surgical findings. Result of 32 conventional CT and 7 MRI were compared with surgical findings in 39 chondrodystrophic dogs with acute thoracolumbar intervertebral disk extrusion. Agreement among investigators was determined for different imaging modalities, and examination times were recorded. In the diagnosis of level of disk extrusion there was agreement of CT and MRI with surgical findings in 100% of dogs. In the diagnosis of lateralization of disk extrusion there was agreement of CT and MRI with surgical finding in 100% and 87% respectively. There were significant differences in average examination duration time between CT (10 min) and MRI (50min). Both CT and MRI appear to be accurate for evaluation of acute thoracolumbar intervertebral disk extrusion in chondrodystrophic dogs but CT seems faster and more immediate view of extruded material.

Abstract
Summary Today Computer Tomography (CT) and Magnetic Resonance Imaging (MRI) are commonly used to evaluate acute intervertebral disk extrusion in condrodystrophic dogs. The purpose of this study was to evaluate the sensitivity and the real utility of CT an MRI in determining level and lateralization of acute thoracolumbar intervertebral disk extrusion in comparison with surgical findings. Result of 32 conventional CT and 7 MRI were compared with surgical findings in 39 chondrodystrophic dogs with acute thoracolumbar intervertebral disk extrusion. Agreement among investigators was determined for different imaging modalities, and examination times were recorded. In the diagnosis of level of disk extrusion there was agreement of CT and MRI with surgical findings in 100% of dogs. In the diagnosis of lateralization of disk extrusion there was agreement of CT and MRI with surgical finding in 100% and 87% respectively. There were significant differences in average examination duration time between CT (10 min) and MRI (50min). Both CT and MRI appear to be accurate for evaluation of acute thoracolumbar intervertebral disk extrusion in chondrodystrophic dogs but CT seems faster and more immediate view of extruded material.
