Objective To investigate the application value of magnetic resonance (MR) susceptibility weighted imaging(SWI) in preoperative grading of brain glioma. Methods The clinical data of 40 patients with brain gliomas confirmed by operation and pathology who were admitted to the hospital from December 2015 to February2018 were analyzed retrospectively. All patients underwent routine MRI plain scan, routine enhanced scan and SWI examination before operation. According to the results of pathological grading, the coincidence rates of MRI routine sequence and SWI sequence for preoperative grading of gliomas were evaluated. Results The coincidence rate of preoperative grading and pathological grading of SWI sequence was significantly higher than that of MRI routine sequence [77.50% (31/40) vs 55% (22/40)] (P<0.05). For SWI sequence, with the increase of pathological grade of tumors, the volume of microhemorrhage in gliomas increased gradually (P<0.05), and the number of micro-vessels in gliomas increased gradually (P<0.05). Conclusion The SWI sequence can be used as an important supplement to the routine MRI sequenceto improve the coincidence rate of preoperative grading of brain gliomas.
