Value of magnetic resonance imaging in the evaluation of patients with complete and high degree block due to intracanal neoplasm.
Magnetic resonance imaging (MRI) of 26 patients with high degree or complete epidural and/or intradural myelographic block, due to primary or secondary neoplasm were analysed. The ratio of false negative MRI was 11.5 per cent. MRI findings were considered to be indicative of lesser block than indicated by myelography in almost 50 per cent of patients. Correlation between the two modalities was highest in cases associated with significant vertebral collapse, malalignment and angulation of the spine and angulation of the spinal cord.
