[Radiodiagnostics of brain tumors before and after operation].

The radiation diagnosis made before and after operation was analyzed in 231 case histories of patients with brain tumors treated in hospitals of St.Petersburg in 2009. Most typical errors of administration and interpretation of radiation diagnostic methods were established. MRI was not performed in 54% of cases, in 32% operative intervention was performed without SCT findings. Contrast enhancement was used but in 68% of observations, angiographic methods--in 8%. Not a single radiation examination was performed in 61% of patients, in 33% SCT was made, in 6%--MRI, only in a third of patients contrast enhancement was used. In 52% of cases control radiation examination was not prescribed in dynamics. The estimation of the data obtained helped to obtain more exact criteria of using radiation methods in patients with tumors of the brain before and after operation.
