| 目的 通过与磁共振胆胰管成像 (MRCP)和MR梯度回波(GE)2D T1W序列增强扫描比较,探讨MR GE快速三维容积式插入法屏气检查(3D-VIBE)序列在诊断胆道梗阻性病变中的价值。方法 132例疑有胆道梗阻性病变而接受包括3D-VIBE序列在内的全套MR检查患者,通过与手术、病理及临床随访结果对照,比较三种MR成像序列对胆道梗阻性病变的诊断价值。结果 ①病灶检测及定位: 118例有明确梗阻部位,共计160个病灶中。MRCP检出149个(93.1%),优于3D-VIBE序列及2D GE T1W序列(P<0.05);②定性诊断:132例患者中,三种方法准确率分别为3D-VIBE 97.7%(129/132)、2D GE T1W 91.7%(121/132)、MRCP 84.8%(112/132),3D-VIBE占优(P<0.05);③推断病灶组织学来源:三种方法准确率分别为3D-VIBE 97.0%(128/132)、2D GE T1W 87.1%(115/132)、MRCP 76.5%(101/132)。它们两两之间的差异均有统计学意义(P<0.05),3D-VIBE效果最佳。结论 MR 3D-VIBE序列对胆道梗阻性病变(特别是非结石性病因)显示出较佳的诊断价值。 |

| Objective To investigate the diagnostic value of a fast gradient-echo (GE) three-dimensional volumetric interpolated breath-hold (3D-VIBE) MR sequence in evaluating obstructive biliary diseases,by comparing with MR cholangiopancreatography (MRCP) and two-dimensional GE contrast-enhanced T1W sequence. Methods 132 patients suspected with obstructive biliary diseases were included into the study who underwent comprehensive MR examination of the upper abdomen, sequences including 3D-VIBE, MRCP and 2D GE T1W. On the basis of surgical / pathological findings and clinical follow-up, the diagnostic value of 3D-VIBE in assessing obstructive biliary diseases was compared with MRCP and 2D GE T1W. Results ① Lesion detection and localization: 118 of 132 patients were found to have definite biliary obstruction sites, accounting for 160 foci of lesions in total. MRCP detected 149 (93.1%) lesions, significantly higher than 3D-VIBE sequence and 2D GE T1W sequence (P<0.05). ② Lesion characterization: The diagnostic accuracies of 3D-VIBE, 2D GE T1W and MRCP were 97.7% (129/132), 91.7% (121/132), and 84.8% (112/132) respectively. The performance of 3D-VIBE was significantly better than 2D GE T1W and MRCP (P<0.05). ③ Lesion histology speculation: The accuracies of 3D-VIBE, 2D GE T1W and MRCP were 97.0% (128/132), 87.1% (115/132), and 76.5% (101/132) respectively. There was statistically significant difference between either two sequences (P<0.05), the performance of 3D-VIBE being the best. Conclusion 3D-VIBE sequence demonstrates super advantages over 2D GE T1W and MRCP in patients with obstructive biliary diseases, especially those of non-calculus etiology. |
