Computed tomography as a possible aid in diagnosis and grading of intracranial glimos

ABSTRACT

In this study, 49 cases of intracranial gliomas were studied by CT scans in an attempt to find out the difference in CT appearance of the various subtypes. The criteria considered in each CT picture were site,attenuationvalue, regularity and margin, calcification, character of enhancement, perifocal edema and mass effect.The predictive value of CT scan for preoperative correct diagnosis of glioma was 75.5% of cases. It was not always possible to put forward the exact pathological subtype of glioma in question, however it is feasible to recognize high and low grade malignancy of the tumor from its CT appearance
