摘要
目的:探讨正常人颅脑浅静脉MRV表现。方法:对106例正常人进行T^1WI、T^2WI、T^2WI-FLAIR、DWI磁共振检查,并用3D-PC法进行颅脑浅静脉MRV成像。结果:①大脑中浅静脉(SMCV)、Trolard静脉、Labbe静脉的显示率分别为64.6%、52.4%、89.6%。②Labbe静脉的形态表现为单干型144例,双干型38例,多干型10例。③注入上矢状窦段桥静脉支数右侧为3.651±0.964,左侧为3.679±0.932。④右侧大脑半球浅静脉引流优势为Labbe静脉>Trolard静脉>SMCV,左侧大脑半球浅静脉引流优势为Labbe静脉>SMCV>Trolard静脉。⑤Labbe静脉在大脑半球的引流优势为左侧>右侧(P<0.05)。Trolard静脉在大脑半球的引流优势为右侧>左侧(P<0.05)。SMCV在大脑半球的引流优势左右两侧基本相当(P>0.05)。结论:MRV是显示颅脑浅静脉解剖形态的有效方法,对临床诊断和治疗有重要意义。
Objective： To study the normal MR venographic findings of the superficial middle cerebral veins（SMCV）. Methods： MR findings including T1WI, T2WI, T2WI-flair, DWI and 3D-PC venography in 106 normal subjects were obtained. Results： ①The visualization rates for SMCV, Trolard＇s vein and Labbe＇s vein were 64.6%, 52.4% and 89.6% respectivily. ② The configuration of Labbe＇s vein was showed a single trunk type in 144 cases, double trunk type in 38 cases and multiple trunk type in 10 cases. ③The bridging veins drained to the superior sagittal sinus were 3.651±0.964 on the right cerebrum, and 3.679±0.932 on the left cerebrum. ④The drainage dominance of superficial vein on the right cerebrum was Labbe＇s vein〉Trolard＇s vein〉SMCV, and on the left cerebrum Labbe＇s vein〉SMCV〉Trolard＇s vein. ⑤The drainage dominance for Labbe＇s vein on the left cerebrum was more efficient than that on the right cerebrum（P〈0.05）, for Trolard＇s vein on the right cerebrum was more efficient than that on the left cerebrum （P〈0.05）, and for SMCV the drainage dominace was equal on both sides （P〉0.05）. Conclusions： MR venography provides a useful method to demonstrate the anatomic features of SMCV, which may be significant for clinical diagnosis and treatment.
