Use of computed tomographic densitometry to quantify contrast enhancement of compressive soft tissues in the canine lumbosacral vertebral canal.

Objectives: To evaluate computed tomography (CT) densitometry as a technique for quantifying contrast enhancement of compressive soft tissues in the canine lumbosacral vertebral canal and to determine whether the degree of contrast enhancement can be used to help predict tissue type or histopathologic characteristics.

Animals: 29 large breed dogs with lumbosacral stenosis.

Procedure: Contrast-enhanced CT of L5-S3 was performed by use of a previously described protocol.
