【摘要】：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(P0.05);右侧TS内径比左侧宽,左右TS内径大小有差别(P0.05)。(2)IJV与TS均是RL,RL,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(P0.05)。(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(P0.05)。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。
[Abstract]:Objective to measure the internal diameters of bilateral internal jugular vein (IJV) and transverse sinus (IJV) by 3D contrast-enhanced magnetic resonance angiography (3DCE-MRAA), and to explore the correlation between venous sinus and IJV.Methods 110 patients (55 males and 55 females) with good vein contrast and no lesions were examined by 3DCE-MRA.Three-dimensional vascular reconstruction was performed by workstation post-processing technique. The diameters of left and right TS and IJV were analyzed by measuring the diameters of the two sides of IJV.The right dominant type was 60. 0%, the left dominant type was 14. 5%, and the equal dominant type was 25. 5%. The inner diameter of TS was related to the sigmoid sinus drainage mode (P 0. 05).Conclusion 3DCE-MRA can clearly display the anatomical features of TS and IJV in sigmoid sinus, and can observe the internal diameter of TS and IJV in both sides objectively, truthfully and accurately.
