[Abstract] Objective: To investigate the advantages of multi-model MRIs in the diagnosis of cerebral venous sinus thrombosis(CVST).Materials and Methods: 17 patients with CVST (6 men, 11 women; mean age, 42 years, range, 22—67 years) were enrolled in this study, including 7 acute CVST, 8 subacute cases and 2 chronic cases. Routine T1WI,T2WI,FLAIR and DWI were performed in all patients, TOF MRV was performed in 14 cases, enhanced MRI was performed in 11 and SWI was performed in 8 cases.Results: Unenhanced FLAIR and T2WI sequence showed disappeared venous sinus flowing void effect andthrombus in the venous sinus with different signal. DWI showed high signal thrombus in the acute CVST patients (8 cases). The involved venous sinus were not displayed on MRV (14 cases) and showed filling defect on enhanced MRIs (10 cases). Dilated veins in drainage area were demonstrated by SWI (5 cases).Conclusions: Multi-model MRIs including FLAIR, T2WI, DWI, MRV, SWI, and enhanced MRI are verysensitive and useful in detecting the thrombus in the venous sinus and provide information about the pathological evolution.
