摘　　要：目的探讨相位导航和膈肌导航在老年患者三维磁共振胰胆管成像(3D-MRCP)薄层扫描中的对比应用研究。方法使用SiemensAera1.5T超导型MR仪对180例老年患者进行相位导航和膈肌导航扫描,采集到的图像进行3D重建,3组图像在解剖结构、图像质量与疾病诊断进行对比。结果在肝内解剖结构显示上,肝内1级胆管、肝外胆管上、中、下及胆囊均能很好地显示出来,差异无统计学意义(P>0.05)。胰管及肝内2级胆管的显示上,膈肌导航明显优于相位导航,差异有统计学意义(P<0.05)。在图像质量上,膈肌导航优良率明显高于相位导航,差异有统计学意义(P<0.05)。胰胆系统疾病的检出率方面,胆囊结石、胆总管结石、胆总管扩张和胰管扩张中确诊率方面相仿,差异无统计学意义(P>0.05)。结论膈肌导航在胰管、肝内2级胆管解剖结构的显示及图像质量的优良率上明显高于相位导航,膈肌导航更适合老年患者3D-MRCP薄层扫描。Objective To explore the comparative application of phase and diaphragmatic navigation in three-dimensional magnetic resonance cholangiopancreatography(3D-MRCP)thin-layer scanning in elderly patients.Methods A total of 180 elderly patients were scanned by phase and diaphragmatic navigation via Siemens Aeral.5T superconducting MR scanner.The acquired images were reconstructed by 3D reconstruction.The anatomical structure,image quality and disease diagnosis were compared between the phase and diaphragmatic navigation groups.Results In liver of anatomy,the liver of primary bile duct,the superior,middle and inferior extrahepatic bile duct and the gallbladder could be well displayed,and the difference was not statistically significant between the two groups(P>0.o5).The display of pancreatic duct and the liver of secondary bile duct of diaphragmatic navigation was significantly better than those of phase navigation(P<0.05).In terms of image quality,the excellent rate of diaphragmatic navigation was significantly higher than that of phase navigation,and the difference was statistically significant(P<0.05).There were no statistically significant differences in the detection rate of pancreatobiliary system diseases,the diagnostic rate of cholelithiasis,common bile duct stones,common bile duct dilatation and pancreatic duct dilatation between the two groups(P>0.O5).Conclusion Diaphragmatic navigation is significantly better than phase navigation in the display of the anatomical structure of the pancreatic duct,the liver of secondary bile duct,and the excellent rate of image quality.Diaphragmatic navigation is more suitable for thin-layer 3D-MRCP scanning in elderly patients.
