Background Glioma is the most common intracranial primary tumor of central nervous system (CNS) and accounts for about 70% of primary adult malignant brain tumors. The optimum therapeutic treatment and prognosis evaluation largely depends on the tumor pathological grades. Objective To evaluate the role of susceptibility weighted imaging (SWI) in grading of cerebral gliomas. The magnetic resonance imaging (MRI) results were compared and correlated to the pathology results to evaluate its role. The pathological grading of the glioma was done according to WHO 2007 classification system. Patients and Methods This was a retrospective study that included 35 adult patients, (11females & 24 males), their ages ranging from 18 years to 73 years. They were pathologically proven glioma patients ranging from grade I to grade IV. All the patients were referred from neurosurgeon to our radiology center (private center). This study was carried out during the period between January 2017 and November 2018. Results In our study, there were a strong positive correlation between both conventional imaging and pathological grading and between pathological and SWI grading. Using SWI sequence in grading of glioma will be very beneficial in patients with contraindication to contrast. Conclusion SWI using 3T MR system may provide quite useful information for preoperative glioma grading. There seems to be a strong positive correlation between pathological grading and SWI grading system for glioma. The main disadvantage for SWI is the extra time added to the usual time of routine MRI protocol used in cases of intra cranial space occupying lesions (SOL).
