| 目的 对比三维容积内插值体部检查（3D-VIBE）与三维T1W快速扰相小角度梯度回波（3D-FLASH）序列肝胆特异期（HBP）钆塞酸二钠（Gd-EOB-DTPA）增强MR胆道成像（CE-MRC）显示胆道系统图像质量及检出病变的差异。方法 回顾性分析101例接受3D-VIBE与3D-FLASH序列HBP Gd-EOB-DTPA CE-MRC患者，包括30例肝移植术后、18例胆道系统疾病及53例肝脏疾病或MRI未见明显异常者，对3D-VIBE-CE-MRC与3D-FLASH-CE-MRC所示胆道系统图像质量进行主观评分及客观评估；对比18例胆道系统疾病3D-VIBE-CE-MRC与3D-FLASH-CE-MRC表现的差异，以及30例肝移植术后患者3D-VIBE-CE-MRC、3D-FLASH-CE-MRC及MR胰胆管成像（MRCP）所测狭窄处胆管直径的差异。结果 3D-FLASH-CE-MRC胆道系统图像质量主观评分高于3D-VIBE-CE-MRC （P<0.05）。3D-FLASH-CE-MRC胆道系统信噪比及对比信噪比均高于3D-VIBE-CE-MRC （P均<0.01）。3D-VIBE-CE-MRC与3D-FLASH-CE-MRC检出胆道系统疾病差异无统计学意义（P>0.05）。于30例肝移植术后共检出35处胆管吻合口狭窄，3D-VIBE-CE-MRC、3D-FLASH-CE-MRC及MRCP显示轻、中度狭窄段直径总体差异均无统计学意义（P均>0.05）；于重度狭窄段处，3D-VIBE-CE-MRC及3D-FLASH-CE-MRC显示直径差异无统计学意义（P=0.999），但均大于MRCP （P均<0.05）。结论 3D-VIBE及3D-FLASH HBP Gd-EOB-DTPA CE-MRC均可用于检出胆道系统疾病，后者图像质量更优。 |

| Objective To compare imaging quality of biliary tract system and detecting diseases with hepatobiliary phase (HBP) gadolinium ethoxybenzyl diethylenetriaminepentaacetic acid (Gd-EOB-DTPA) contrast-enhanced MR cholangiography (CE-MRC) with three-dimensional volume interpolated body examination (3D-VIBE) and three-dimensional T1W fast low-angle shot (3D-FLASH) sequences. Methods Data of 101 patients who underwent HBP Gd-EOB-DTPA CE-MRC with 3D-VIBE and 3D-FLASH sequences were retrospectively analyzed, including 30 cases after liver transplantation, 18 cases with biliary tract system diseases and 53 with liver diseases or without obvious abnormalities MRI findings. The subjective scoring and objective evaluation on imaging quality of biliary tract system, as well as the detection of biliary tract system diseases were compared between 3D-VIBE-CE-MRC and 3D-FLASH-CE-MRC, while the diameter of stenosis biliary tract after liver transplantation were measured and compared on 3D-VIBE-CE-MRC, 3D-FLASH-CE-MRC and MR cholangiography (MRCP). Results The subjective score of imaging quality of biliary tract system on 3D-FLASH-CE-MRC was higher than that om 3D-VIBE-CE-MRC (P<0.05). The signal noise ratio and contrast noise ratio of biliary tract system on 3D-FLASH-CE-MRC were higher than those of 3D-VIBE-CE-MRC (all P<0.01). There was no significant difference of the detection of biliary tract diseases between 3D-VIBE-CE-MRC and 3D-FLASH-CE-MRC (P>0.05). Totally 35 bile duct anastomotic stenosis were detected in 30 cases after liver transplantation. For mild and moderate stenosis, no significant difference of overall stenosis diameter was found among 3D-VIBE-CE-MRC, 3D-FLASH-CE-MRC and MRCP (all P>0.05). For severe stenosis, no significant difference of stenosis diameter was observed between 3D-VIBE-CE-MRC and 3D-FLASH-CE-MRC (P=0.999), while stenosis diameter of both 3D-VIBE-CE-MRC and 3D-FLASH-CE-MRC were larger than that of MRCP (both P<0.05). Conclusion Both 3D-VIBE and 3D-FLASH HBP Gd-EOB-DTPA CE-MRC could be used to detect biliary tract system diseases, and the latter had better imaging quality. |
