    Abstract:
    To clarify the significance of MR imaging and the present status of CT, angiography, and myelography supplemented by CT (M-CTM), the radiological findings of 50 spinal tumors were reviewed and analyzed. MR imaging was most effective for visualizing morphological features such as the margins and/or inner structures of the tumors. CT was also effective for imaging "dumbbell" neurinomas and extradural tumors. Angiography was necessary in one hemangioblastoma and in cervical extradural tumors. M-CTM visualized the morphology of intradural extramedullary tumors and extradural tumors, but provided no new information in most of these cases. It was concluded that when using MR the indications for CT, angiography, and M-CTM are limited and that CT or angiography should be performed only in selected cases. M-CTM appeared to be unnecessary.
