摘　　要：目的：观察大脑内静脉及其属支正常解剖结构、变异及临床意义。方法采用320排CT对142例正常人进行一站式颅脑成像检查，观察大脑内静脉及其属支解剖特点。结果大脑内静脉、丘纹静脉、透明隔静脉、前终静脉、后终静脉、直静脉显示率分别为100%、100%、98.9%、95.4%、93.7%、48.6%。大脑内静脉分4型，以 IA型为主，且大多数位于同一水平面，部分呈镜像对称；前终静脉根据引流部位不同分4型，其中以引流入丘纹静脉最常见，引流模式与静脉角、假静脉角无统计学意义（P＆gt;0.05）。直静脉显示与后终静脉发育情况有统计学意义（P＜0.05）。结论320排 CT 一站式扫描是一种有效、无创、充分显示活体大脑内静脉及其分支解剖的一种重要检查方法，能真实再现静脉血管解剖、走行及形态学变化。Objective To observe clinical significance、anatomy and variation of normal internal cerebral veins and their tributa-ries.Methods The studies included 284 sides in 142 patients.The patients were performed with 320-detector Row CT One-stop Scanning.Then,the anatomical features of internal cerebral veins and their tributaries were evaluated.Results The detection rate of internal cerebral veins（ICA）、thalamostriate veins（TSV）、septal veins（SV）、anterior caudate nucleus veins、posterior caudate nucleus veins and lateral direct veins was 100%、100%、98.9%、95.4%、93.7%、48.6%.Type of IA was seen frequently in four types of ICA,the parts of ICV and their tributaries were mirror symmetry,the majorities of ICA were located the same plane.Anterior cau-date nucleus veins were classified four types on basis of these different draining patterns,they were drained to TSV commonly.There was no significant difference between venous angle or false venous angle and type of their draining（P＆gt;0.05）.There was significant difference between detection rate of lateral direct veins and development of posterior caudate nucleus veins（P＜0.05）.Conclusion 320-detector Row CT One-stop Scanning was an important method that internal cerebral veins were detected effectively and non-inva-sively,observed anatomy,course and morphological change of ICV.
