[Assessment of the degree of resection of high grade supratentorial gliomas with early postoperative magnetic resonance].
In this paper we report the results of a prospective study in which we evaluate the degree of tumor removal of 25 supratentorial high grade gliomas by means of an MRI performed in the early postoperative period. In all cases, there was preoperative enhancement 8 patients had been previously operated on while the others had their first operation. In all cases the postoperative early MRI was performed within the first week and in 15 within the first 3 days. In order to evaluate the degree of tumor removal the presence or not of enhancement was considered and if it existed, classified as linear or nodular.


RESULTS
To avoid postsurgical artifacts it is important to perform the MRI as soon as possible after surgery, especially within the first 3 days. Generally, linear enhancement disappeared on subsequent follow-up examinations, showing that it probably does no represent residual, tumor while nodular enhancement usually does. Survival with the high-grade tumors was slightly higher in the group without postoperative enhancement or linear one than in the group with nodular enhancement but the difference was not significant.
