MRI动态实景渲染技术在矢状窦旁脑膜瘤Sindou分型中的应用
Application of MRI-based cinematic volume rendering technique in Sindou classification of parasagittal sinus meningioma
摘要
Abstract
Objective To investigation the application value of the cinematic volume rendering technique(cVRT)based on contrast enhanced three dimensional T1 magnetization-prepared rapid gradient echo(CE-3D T1MPRAGE)in preoperative evaluation of parasagittal meningioma(PSM).Methods This retrospective study included 108 patients with solitary PSM confirmed by surgical pathology,all of whom completed CE-3D T1MPRAGE and MR venography(MRV)examinations.The cerebral venous system and PSM were visualized using cVRT based on CE-3D T1MPRAGE.The Sindou classification of PSM was performed using cVRT,and its diagnostic accuracy,sensitivity,and specificity were calculated.The sagittal sinus wall and sinus angles adjacent to the tumor were measured,and one-way ANOVA was used to compare the sagittal sinus angles of PSMs with different Sindou classifications.The display of PSM draining veins and collateral circulation on cVRT and MRV was observed,and McNemar's test was used to compare the display rates of the two examinations.Result The diagnostic accuracy of cVRT for Sindou classification of PSM was 89.81%,with high sensitivity(94.88%,100%)and specificity(85.45%,91.03%)for typeⅠand typeⅥ,respectively.There were statistically significant differences in multiple sagittal sinus angles between typeⅤand typeⅠwithin Sindou types(P＜0.05).The display rates of peritumoral draining veins and superficial venous collaterals on cVRT(98.14%,91.67%)were higher than those on MRV(74.07%,78.70%),but the display rate of deep venous collaterals on cVRT(54.36%)was lower than that on MRV(85.18%)(all P＜0.05).Conclusion cVRT imaging based on CE-3D T1MPRAGE can accurately classify PSM according to Sindou,effectively displaying peritumoral draining veins and superficial venous collaterals,providing more accurate references for surgery.关键词
