[Imaging of neoplastic changes in the spine using MR tomography]

The value of MR tomography for examining vertebral infiltration by malignant disease and the use of various techniques was examined retrospectively in a material of 68 examinations in 62 patients suffering from metastases, plasmacytomas, primary vertebral tumours and vertebral infiltration from extra-osseous tumours. It was shown that the method is superior to all other imaging methods for demonstrating changes in the bone marrow. The extent of the disease and involvement of neighbouring structures is shown more completely in cases where the disease extends beyond the vertebrae. Improved soft tissue contrast and the availability of various planes are definite advantages, as compared with CT. Tissue diagnosis, however, is not improved by MRT.
