Objective To evaluate the application value of 1.5T magnetic resonance threedimensional sampling perfection with application-optimized contrasts using different flip angle evolution (3D-SPACE) sequence in preoperative evaluation of parasagittal meningioma. Methods 35 patients with pathological-confirmed parasagittal meningioma were selected. All the patients underwent MRI, Contrast-enhanced magnetic resonance venography (CE-MRV) and 3D-SPACE scanning before operation. The typing and collateral circulation of parasagittal meningioma was observed by two observers. Results According to the golden standard by operation, the total accuracy of CE-MRV and 3D SPACE for parasagittal meningioma typing was 80.0% and 91.4%, respectively, and 3D SPACE was higher than CE-MRV (P<0.05). The correct display rates of collateral circulation by CE-MRV and 3D SPACE were 80.6% and 82.5% (P>0.05), respectively. Conclusion 1.5T MR 3D-SPACE can improve the accuracy of parasagittal meningiomas typing and clearly show the collateral circulation, which has important significance for preoperative evaluation of parasagittal meningioma.
