摘要
目的:比较二维快速平衡稳态进动序列(2D-FIESTA)和肝脏容积加速采集序列(LAVA)对门静脉系统成像的临床应用价值。方法:对23例肝硬化门静脉高压患者(肝硬化组)和25例无肝疾病及相关疾病患者(正常组)行2D-FIESTA扫描及LAVA扫描,分别测量门静脉主干、肠系膜上静脉和脾静脉的直径,比较两种检查方法的符合情况。结果:2D-FIESTA和LAVA对门静脉系统各组血管直径的测量差异无统计学意义,对门静脉系统的癌栓及解剖变异都能很好地显示。肝硬化组中门静脉主干、肠系膜上静脉和脾静脉直径明显大于正常组。结论:2D-FIESTA和LAVA可以比较满意地评价门静脉系统的情况,两者各有优势。
Objective To compare the clinical value of 2D-FIESTA with that of LAVA in image forming of portal venous system. Methods Abdominal dynamic contrast-enhanced MRI (LAVA sequence) and coronal 2D-FIESTA were performed on 48 patients (23 with portal hypertension and 25 non-cirrhotic subjects) to measure the diameters of main portal trunk (MPT), superior mesenteric vein (SMV), splenic vein (SV). The findings of the two procedures were compared. Results The diameters of MPT, SMV, and SV did not differ significantly between the two groups. Caner embolic and anatomical abnormalities were clearly demonstrated on both scanning methods. The diameters of MPT, SV, and SMV were markedly greater in the cirrhosis group than in the control group. Conclusion Both 2D-FIESTA and LAVA can ideally demonstrate the portal venous system in all patients and each technique has its own superiority.
