目的 联合应用MRI的双激发式稳态自由进动(BTFE)序列与增强T1高分辨率各向同性容积激发(e-THRIVE)成像序列分析岩静脉的正常解剖结构及其与同侧三又神经的空间毗邻关系.方法 选取41例面肌痉挛及气叉神经痛患者.采用飞利浦公司ACHIEVA NOVA DUAL A-serial 1.5T磁共振扫描仪对患者进行成像.成像序列为BTFE与e-THRIVE序列,主要观察脑桥小脑角区岩静脉及其与三叉神经的窄间毗邻关系.结果41例共82侧岩静脉及同侧三叉神经均显示清晰;岩静脉位于蛛网膜下腔,呈局部游离状态.岩静脉主干支数为1、2、3支者分别为70侧(86%)、10侧(12%)、2侧(2%).37例共74侧岩静脉(91%,BTFE、e-THRIVE序列)位于三叉神经根的背外方,3例共6侧岩静脉(7%,e-THRIVE序列)位于神经根的腹外方,1例共2侧岩静脉(2%,BTFE 序列)位于神经根的正上方.结论 联合应用BTFE与e-THRIVE序列可以清晰显示岩静脉及三叉神经,并可以准确评估两者间的空间毗邻关系,为三叉神经痛患者行微血管减压术术前提供局部影像学解剖信息.

Objective To analyze the normal anatomy of petrosal vein and the space adjacent relationship between the petrosal vein and the homolateral trigeminal nerve by balanced turbo field echo (B-TFE) Cine-MR imaging and enhanced T1 high-resolution isotropic volume excitation (e-THRIVE)imaging.Methods Forty-one patients with facial spasm and epileptiform neuralgia were selected and taken a scan with ACHIEVA NOVA DUAL A-serial 1.5T MR machine using the BTFE and e-THRIVE series.The space adjacent relationship between the petrosal vein and the trigeminal nerve in cerebellopontine angle were observed.Results The 82 sides of petrosal veins and homolateral trigeminal nerves (41 cases) were displayed well.Petrosal veins were located in cavitas subarachnoidealis,partly in free state; the number of trunk ofpetrosal vein could be 1,2,3,respectively,responding to 70 (86%),10 (12%),2 (2%).The petrosal veins located in the dorsal-lateral of trigeminal nerve were found in 74 sides (37 cases,91%,by BTFE,e-THRIVE series),the petrosal veins located in the ventri-lateral of trigeminal nerve in 6 sides (3 cases,7%,by e-THRIVE series),and the petrosal veins located in the right upon trigeminal nerve in 2 sides (1 cases,2%,by BTFE series).Conclusion B-TFE MR imaging and e-THR/VE imaging,showing the petrosal veins and trigeminal nerves clearly and evaluating their relationship accurately,can provide information of topographic anatomy before microsurgical vascular decompression.
