目的：利用三维对比增强磁共振血管成像（3DCE‐MRA）对双侧颈内静脉（IJV）及横窦（TS）内径进行测量，并探讨静脉窦和IJV相关关系。方法选择110例行颈部动脉3DCE‐MRA检查示静脉显影良好、无病变的受检者，男、女各55例。利用工作站后处理技术进行血管三维重建，对两侧IJV进行各径线测量，分析左右TS及IJV的内径大小之间关系。结果（1）IJV内径在测量点J1、J2、J3依次逐渐减小。IJV内径右侧宽于左侧，左右IJV内径比较差异有统计学意义（P＜0．05）；右侧TS内径比左侧宽，左右TS内径大小有差别（P＜0．05）。（2）IJV与TS均是R＞L，R＜L，R＝L各自所占比例依次逐渐减小。TS较大侧与IJV较大侧一致，TS内径大小与IJV内径大小存在相关性（P＜0．05）。（3）乙状窦的引流方式，右优势型占60．0％，左优势型占14．5％，等优势型占25．5％；TS的内径大小与乙状窦引流方式有关（P＜0．05）。结论3DCE‐MRA可以清晰显示乙状窦、TS及IJV的解剖特征，能客观、真实、准确地观测两侧TS和IJV的内径值。

Objective To measure the sizes of the left and right internal jugular veins (IJV) and transverse sinuses (TS) with three dimensional contrast‐enhanced MRA(3D CE‐MRA) ,and discuss the correlation of cerebral venous sinus and IJV .Methods One hundred and ten patients without vasculopathy and blood flow abnormalities were selected for 3D CE‐MRA ,55 cases for each gender .The images were taken three‐dimensional reconstruction on work‐station by different software .The normal IJV and TS was measured and the statistical comparison between the bilateral IJV and TS was analyzed .Results (1)The inside diameter of IJV re‐duced in turn at the measurement point of J1 ,J2 and J3 .The internal diameter of the right side of IJV was broader than left one ,and there was significant difference between the size of left and right side (P<0 .05) in these measurements .The internal diameter of the right side of TS was broader than left one ,there was difference between the sizes of the left and right of TS (P<0 .05) .(2)The proportion of R>L ,R<L ,R=L decreased in the inside diameter of the IJV and TS .The wider side of TS was consistent with the wider side of IJV .The inside diameter of TS was related to the inside diameter of IJV(P<0 .05) .(3)The drainage pattern of the sigmoid sinus was as follow ,the right type(60 .0% ) ,left type(14 .5% ) ,and intermediate type (25 .5% ) .The sizes of TS was relat‐ed to the drainage methods of sigmoid sinus (P<0 .05) .Conclusion The 3D CE‐MRA image could clearly display the anatomical char‐acteristics of the sigmoid sinus ,TS and IJV ,and the internal diameter of TS and IJV could be estimated accurately ,truly and objectively .
