Abstract：Objective To evaluate the value of susceptibility weighted imaging (SWI) and 1H magnetic resonance spectroscopy
(1H-MRS) in diagnosis of glioma. Methods According to WHO classification method, 81 patients with glioma were divided into
three groups: 30 cases of grade II, 13 cases of grade III and 38 cases of grade IV. All patients underwent SWI and 1H-MRS imaging
before operation, and were confirmed by postoperative histopathology. All parameters of SWI and 1H-MRS were measured by
post-processing, and then were analyzed statistically. Results Parameter r NAA had statistical significance in differentiating grade
II from grade III (P<0.05). r Cho/NAA and r NAA/Cr had statistical significance in differentiating grade II from grade III and grade
II from grade IV (P<0.05). There were significant statistical differences in SWI among groups (P<0.05). By combining these two
techniques, the AUC, sensitivity and specificity were greater than the application of a single technique. Conclusion The diagnostic
efficiency of combined SWI and MRS in grading of glioma is higher than that of single technique. SWI has higher diagnostic efficacy
than 1H-MRS.
