[Magnetic resonance tomography and skeletal scintigraphy in spondylodiscitis]

12 patients were diagnosed as suffering from spondylodiscitis by means of clinical and laboratory investigations. Magnetic resonance tomography (MRT) and bone scintigraphy (with Tc 99m-diphosphonate) were performed and 6 patients had further MRT follow up investigations. In the initial state of disease the comparison of MRT and bone scan both revealed a sensitivity of 92%. The specificity was 83% for MRT and 50% for bone scintigraphy, respectively. Therefore we conclude MRT is a more specific diagnostic tool in patients with spondylodiscitis. 6 patients were followed up with additional 13 MRT scans. During the first two months of treatment period in most of the patients more distinct pathological findings were seen in MRT in comparison with MRT at the start. No signs of any improvement despite effective treatment were found in the first three months of therapy.
