目的探讨屏气MR胰胆管成像 (MRCP)的扫描技术。方法 截选我院2012 年1月-2014年10月期间100例患者作为本 次研究对象，所有研究对象均采用SS-FSE 序列MRCP扫描检查，同时对结果加以分 析。结果 经研究发现，(1)胆胰管显示方 面，采用厚层投射MRCP效果明显优于MIP 法，P＜0.05；(2)小结石显示：采用MIP 法2D原始图像的显示率明显优于MIP重建 MRCP及厚层投射MRCP，P＜0.05；(3)腔 外肿块显示：采用无脂肪抑制2D原始图 像显示效果明显优于脂肪抑制2D图像，P ＜0.05。结论 临床应用MRCP扫描时采用 斜冠状面进行扫描具有较好效果，同时采 用2D原始图像可较好地显示腔内小病灶及 腔外肿块，有利于临床诊断。

Objective Explore the breath-hold MR cholangiopancreatography (MRCP) scanning technology. Methods Cut-off election in our hospital in January 2012 - October 2014 period as 100 patients in this study, all subjects are used in SS-FSE MRCP scan sequence, but to analyze the results. Results The study found that (1) bile duct display, the use of a thick layer of MRCP better than MIP projection method, P＜0.05; (2) small stones Show: MIP method using 2D display the original image was significantly better than MIP reconstruction MRCP and thick projection MRCP, P＜0.05; outside (3) cavity tumors show: no fat suppression original 2D image display is better than the fat suppression 2D image, P＜0.05. Conclusion Clinical application of MRCP scan using oblique coronal scan with good results, while using the original 2D image can better display outside the cavity and the cavity mass of small lesions, help clinical diagnosis.
