This study aims to demonstrate the value of magnetic resonance black-blood imaging （MRBTI） for differentiating acute and chronic cerebral venous thrombosis (CVT) as well as the diagnosis accuracy of CVT in segment levels. The SNR and CNR of the acute CVT group were significantly higher than that of the chronic group. The sensitivity and specificity of MRBTI were 95.6% (152 /159) and 98.0% (352 /359), respectively. Furthermore, the sensitivity of MRBTI in detecting acute thrombus is up to 100%, compared with 88.5% in the chronic group, which means MRBTI has high sensitivity for early diagnosis.
