| 摘 要： | 目的探讨非对比剂磁共振血管成像(NC-MRA)评估肠系膜上动脉(SMA)、腹主动脉(AA)和肾静脉(RV)的解剖关系及左肾静脉(LRV)受压情况的可行性研究。资料与方法搜集MSCTA或CE-MRA诊断为胡桃夹综合征的9例患者,在1.5TMRI上采用多翻转恢复空间标记脉冲(SLEEK)标记动脉血、静脉血分别显示动脉系统(SMA与AA)和静脉系统(RV),最后移除所有翻转带扫描同时显示SMA、AA和RV。由两名放射科主任医师评估NC-MRA的图像质量及SMA、AA和RV解剖关系;LRV受压情况。测量SMA与AA之间的夹角(a),在LRV横断面上分别测量SMA和AA间隙内LRV的最小面积(S1)及近左肾侧LRV的最大面积(S2),并计算S2和S1的比值(q),与MSCTA及CE-MRA对照,并进行统计学分析。结果 NC-MRA在显示SMA、AA和RV的解剖关系及LRV受压情况与MSCTA和CE-MRA具有很好的相关性。NC-MRA测量SMA与AA的夹角(a)平均值,S2和S1及S2与S1比值(q)的平均值分别为22.19、(0.23±0.10)cm2、(0.89±0.29)cm2、4.30;而MSCTA和CE-MR...

| Abstract: | Objective To evaluate the ability of NC-MRA in displaying the anatomical relationship and the adjacent structure between SMA,AA and RV and in showing the degree of LRV compression.Materials and Methods 9 Nutcracker Syndrome(NCS) subjects diagnosed by MSCTA or CE-MRA were collected.A SLEEK prepared 3D FIESTA sequence was developed to present the arterial system(SMA and AA) and venous system(RV) respectively on 1.5 T MRI systems,and to display them simultaneously when removed all inversion.Two experienced rad... |
