【Abstract】 ObjectiveTo compare the diagnostic value of soft tisse imaging （fully flow encoded modulus， FFE/M），vascular imaging （phase contrast angingraphy modulus，PCA/M），and thecombination of PCA/MandFFE/M inthree-dimensional phase-contrast magneticresonancevenography （3D-PC-MRV）forcerebral venoussinus thrombosis.MethodsA total of 26 patients with 234 segments who underwent magnetic resonance venography were included and divided into three groups： PCA/M group，F(xiàn)FE/M group，and PCA/M combined with FFE/M group.Two experienced radiologists independentlydiagnosed thecerebral venous sinus disorders.Statistical analyses，including χ2 test，cross -tabulation，and Kappa analysis，were performed to evaluate the results.ResultsThere were statistically significant differences among the three groups （ P <0.05）.Using angiography as the gold standard，the sensitivityof the PCA/M combined with FFE/M group for detecting cerebral venous sinus thrombosis was 97.1% which was higher than that of theFFE/M group，and the diference was statistically significant.The sensitivity for detecting cerebral venous sinus stenosis was 91.7% ，which was higher than that of the PCA/M group，and the difference was statistically significant.The specificity was 99.4% forboth groups，which was higher than that of the FFE/M groupandthe PCA/M group，and thediferences were statisticallysignificant.The Kappa value for agreement with the angiographygold standard was O.958，indicating good consistency.ConclusionIn intracranial venous magnetic resonance imaging，the diagnostic performance of the PCA/M combined with FFE/M approach in 3D-PCMRV is superior to the individual evaluation of PCA/MandFFE/M，making it a preferred method for examination.

腦靜脈竇血栓形成（cerebralveinandsinusthrombosis，CVST）是腦卒中的重要原因之一，為腦血管意外的一種特殊類型，其臨床癥狀復(fù)雜、無特異性，給臨床早期診斷帶來了很大困難，但隨著精準醫(yī)療的發(fā)展及生存要求的提高，對于早期診斷、及時治療、減少并發(fā)癥的需求越來越高[1-3]。（剩余7066字）
