Advantages of diagnosing bacterial spondylitis with magnetic resonance imaging.

We report on 16 cases of suspected spondylitis in which we used magnetic resonance (MR) imaging to confirm or exclude the diagnosis. MR has several advantages, one of which is to permit diagnosis of this disease in the early stages without major risks. In addition, MR permits recognition of complications such as paravertebral or intraspinal abscess formation with a high security and accuracy. Moreover, it is possible to show spondylitic alterations in three different planes. To differentiate this disease from metastatic or tumorous lesions the technique with T1- and T2-weighted images is helpful. As a result, MR imaging can shorten the time between onset and diagnosis of spondylitis.
