This study explores the feasibility of MR 3D T1 SPACE sequence in diagnose and differential diagnosis of Cerebral sinus venous thrombosis (CSVT) . The clinical phase of CVST in accordance with onset of symptom often lags behind image characters. Results showed that no obvious scientific difference was found among clinical phase groups. However, the differences between the acute, subacute and chronic imaging groups were statistically significant. Besides, CE rate of CVST in superficial veins was found higher than that in deep veins. MR 3D T1 SPACE has the potential to improve the accuracy of early diagnosis of CVST.
