Abstract

Proliferating process within the vertebral canal is one of the main indications for MRI examination. The latter allows to differentiate between intra- and extramedullary tumors, as well as between sub- and extradural ones. The tumor may be precisely localized; besides, its size and relation to the vertebral column and its surrounding tissues can be evaluated. Assessment of both the degree and type of post-contrast enhancement helps to define the structure of the tumor. In the case of intramedullary processes, the tumor can be distinguished from the swelling area, and the image of real magnitude of the alteration can be obtained. In cases of supradural tumors contrast agents are administered in order to evaluate treatment efficacy and the degree of the medulla infiltration.
