Abstract:
Objective To explore the relationship between the amount of bleeding and the histopathologic grade of cerebral glioma with susceptibility weighted imaging (SWI), so that to assess the diagnostic value of SWI in grading cerebral glioma. Methods Totally 30 patients with cerebral glioma underwent SWI. The area of hemorrhage of every slice displayed in SWI was measured with software. The rate and amount of bleeding were compared between high and low grade tumors. Results There was no statistical significance in the incidence of detected bleeding on SWI (P=0.064), though it was higher in highly malignant group (80.00%) than that in low grade group (46.67%), while there was statistical significance in the amount of bleeding detected on SWI (Z=-2.275, P=0.026) between highly malignant group and low grade group. Conclusion The amount of tumor hemorrhage displayed in SWI is valuable for the preoperative grading of cerebral glioma.
