| 目的 探讨流入反转恢复（IFIR）序列在肝移植术后门静脉成像中的应用价值。方法 对26例肝移植术后患者依次行上腹部IFIR序列成像和对比增强MRA（CE-MRA），由2名医师采用盲法对门静脉显示质量进行评分，比较2组图像评分的差异并测量吻合口直径。比较2组图像测量值的差异，评价医师间图像质量评分和测量吻合口直径的一致性。结果 26例IFIR序列和CE-MRA均能显示门静脉主干及门静脉左、右支近端血管，图像质量≥ 3分者分别为92.31%（24/26）和96.15%（25/26）。2名医师对IFIR序列与CE-MRA图像质量评分差异均无统计学意义（医师1：Z=-1.077，P=0.282；医师2：Z=-0.629，P=0.529）。2组图像吻合口直径测量值间差异均无统计学意义（医师1：t=0.369，P=0.546；医师2：t=0.020，P=0.889）。2名医师图像质量评分和测量吻合口直径的一致性好。结论 IFIR序列可作为评估肝移植术后门静脉的有效方法之一。 |

| Objective To explore the application value of inflow reversal recovery (IFIR) sequence in portal vein imaging after liver transplantation. Methods IFIR sequence imaging and contrast-enhanced MRA (CE-MRA) were performed successively on the upper abdomen in 26 patients after liver transplantation. The portal vein display quality of 2 kinds of images was scored and compared independently by 2 radiologists. The diameter of anastomotic stoma was measured and compared, and the consistency of image quality scores and anastomotic diameters were evaluated between the 2 radiologists. Results Both IFIR sequence and CE-MRA could show the main portal vein and the proximal left and right branches of the portal vein in 26 patients, and the image quality score ≥ 3 points was 92.31% (24/26) and 96.15% (25/26), respectively. There was no significant difference of image quality score of IFIR sequence and CE-MRA evaluated by 2 radiologists (radiologist 1:Z=-1.077, P=0.282; radiologist 2:Z=-0.629, P=0.529), nor of the measured diameter of anastomosis between IFIR sequence and CE-MRA (radiologist 1:t=0.369, P=0.546; radiologist 2:t=0.020, P=0.889). The consistency of image quality scores and anastomotic diameters evaluated by the 2 radiologists was good. Conclusion IFIR sequence can be used as an effective method to evaluate portal vein after liver transplantation. |
