Characteristics analysis of cerebral venous sinus thrombosis CT and MRI imaging

Objective: To explore the cerebral venous sinus thrombosis in the performance characteristics of CT and MRI. Methods: Thirty-five patients with clinically diagnosed by cerebral venous sinus thrombosis (CVST) patients CT and MRI imaging were analyzed retrospectively. Results: 8 patients with thrombosis in the straight sinus and inferior sagittal sinus, 15 cases in the superior sagittal sinus, transverse sinus involving 7 patients-sigmoid sinus, 5 cases of multiple sinus involvement, 7 patients involving the brain cortex of deep vein and draining vein; 10 cases of acute CT scan in patients with direct or indirect signs could be seen; MRI scan showed 32 cases of cerebral venous sinus typically seen in patients with abnormal signal or high signal flow void effect disappears. MRV examination showed segmental or whole involved sinus occlusion. Conclusion: Brain CT scan diagnosis of acute CVST is a simple and effective way; for sub-acute and chronic CVST patients, MRI scan and MRV revealed characteristic performance, more reliable for the diagnosis of CVST.
