摘要
目的:比较磁共振胰胆管成像技术的2种成像方法,探讨有助于临床诊断胆系病变的磁共振检查的最佳方法。方法:分析经手术病理或活检证实的35例胰胆管病变患者2种不同方法(单层TSE序列及多层HASTE序列)MRCP影像表现,比较二者显示胰胆管病变的优缺点。结果:单层TSE序列采集时间短,空间分辨率高,受运动伪影影响小;多层HASTE序列采集时间较长,运动伪影明显。结论:单层TSE-MRCP成像结合常规SE及梯度序列冠轴位相扫描是胰胆管病变的磁共振检查的最佳方法之一。
Objective:To study MRCP methods for diagnosing the biliary tract diseases. Methods:Two acquisition techniques of MRCP (single-slice TSE-MRCP and multislice HASTE-M-RCP) were used in 35 patients with pathologically proven biliary tract diseases. Resuits:Single-slice acquisition had a shot acquisition time, high spatial resolution and less moving artifact; muhislice acquisition had a long acquisition time and more moving artifact. Conclusion: The single-slice TSE-MRCP is one of the best techniques in the diagnosis of biliary tract diseases.
