Abstract
Objective To compare the diagnostic value of Lwo-dimensional time-of-flight (2D TOF) magnetic resonance venography in the sagittal plane, 2D TOF in the coronal plane, and ihree-dimensional contrast-enhanced magnetic resonance venography (3D CE-MRV) for intracranial venous sinus disease. Methods Thirteen patients were suspected of having intracranial venous system abnormalities in the Neuro-surgical Outpatient Department, Xuanwu Hospital, Capital Medical University were included from July 2011 to March 2012. 2D TOF and 3D CE-MRV scan in the sagittal and coronal planes were performed at the same time. Maximum intensity projection (MIP) was used for 3D reconstruction. The diagnostic results were compared with DSA. The sensitivity, specificity, positive predictive value, negative predictive value and Kappa value of the 8 main vein structures (superior sagittal sinus, straight sinus, bilateral transverse sinus, bilateral sigmoid sinus and bilateral transverse-sigmoid sinus junction) of the 2D TOF in the sagittal plane, 2D TOF in the coronal plane, and 2D TOF in the sagittal plane in combination with coronal plane were calculated. Results ①Compared to the diagnostic results of DSA, there was significant difference in using the diagnosis with TOF in the sagiLLal plane or coronal plane alone ( all P ＜ 0. 05 ) , but there was no significant difference after combining the Lwo methods (XM2 =1.500, P＞0. 05). ②Taking DSA as a standard, the consistency of 3D CE-MRV and DSA conclusions was the highest (P＜0.01, Kappa =0. 933). The sensitivily, specificity, positive predictive value, and negative predicting value were 94.4% , 98. 8% , 94.4% , and 98.8% , respectively. The consistency of the diagnostic results of 2D TOF in the coronal plane in combination with sagittal plane and the DSA conclusions were higher than that of 2D TOF in the coronal plane or 2D TOF in the sagittal plane alone (Kappa values were 0.815, 0.635, and 0.608, respectively). Conclusion When it is difficult to diagnose intracranial venous sinus disease with 2D TOF in the coronal plane or 2D TOF in the sagittal plane a-lone, the 2D TOF sequence of other direction should be added, the collaborative diagnosis of both may improve the accuracy of diagnosis. The diagnosis of 3D CE-MRV and DSA showed a high degree of consistency. They may be used as a routine examination for the diagnosis of cerebral venous sinus disease.关键词
