Computed tomography CT is an established technique for localizing disc extrusions in dogs however the effect of multi-planar reformatting MPR on surgeon diagnostic performance has not been previously described. The purpose of this study was to test the effect of MPR CT on surgeon diagnostic accuracy certainty and agreement for localizing thoracolumbar disc extrusions in dogs. Two veterinary surgeons and one veterinary neurologist who were unaware of surgical findings independently reviewed randomized sets of two-dimensional 2D and MPR CT images from 111 dogs with confirmed thoracolumbar disc extrusions. For each set of images readers recorded their localizations for extruded disc material and their diagnostic certainty. For MPR images readers also recorded views they considered most helpful. Diagnostic accuracy estimates mean diagnostic certainty scores and inter-observer agreement were compared using surgery as the gold standard. Frequencies were compared for MPR views rated most helpful. Diagnostic accuracy estimates were significantly greater for MPR vs. 2D CT images in one reader. Mean .
