This paper presents a comparison of the diagnostic value of CT studies and conventional radiological diagnosis, based on 46 CT studies, in patients with inflammatory bone lesions of the spine (n = 20) before and after surgical interventions (n = 12). In cases with a tentative clinical diagnosis of an inflammatory bone lesion, CT will not supplant conventional radiological diagnosis as the roentgenologic method of first choice. The superiority of CT is based on its ability to demonstrate intraspinal, paravertebral, and intervertebral complications. Osseous incorporation of spongiosa parts and the healing of paravertebral and intraspinal complications can be assessed more easily and accurately with CT.
