摘　　要：目的比较常规胰胆管成像与压缩感知胰胆管成像对胰胆系管道扩张成像及胰胆管结构显示的图像质量,以供临床选择更合适的成像方法。材料与方法回顾性研究2019年7月至2019年12月之间在河南省人民医院就诊的胰胆管扩张患者37例,在西门子1.5 T磁共振机器上行常规及压缩感知磁共振胰胆管成像。采用5分制评价图像质量,由1名临床经验大于5年的医师及1名临床经验为2年的医师进行评分,结果使用SPSS软件配对t检验进行分析。结果压缩感知胰胆管成像与常规磁共振胰胆管成像(magnetic resonance cholangiopanceatography,MRCP)在整体图像质量、胆管扩张及胰管扩张显示方面没有统计学差异(P>0.05)。扩张胆管的评分均比整体图像质量评分与胰管扩张评分高,而结石所致胆管扩张和肿块所致胆管扩张图像评分并没有统计学差异。结论压缩感知胰胆管成像与常规胰胆管成像相比,图像质量无明显差异,但压缩感知胰胆管成像能有效地缩短成像时间,并减少呼吸运动伪影。Objective:To compare the image qualities of conventional cholangiopancreatography and compressed-sensing cholangiopancreatography imaging for biliary dilatation imaging and bile duct structure display for clinical selection of more suitable imaging methods.Materials and Methods:A retrospective study of 37 patients with pancreaticobiliary duct dilatation in Henan Provincial People’s Hospital from July 2019 to December 2019 was investigated.Patients underwent conventional MRCP and CS-MRCP on a 1.5 T scanner(MAGNETOM Sempra,Siemens).A 5-point scale was used to evaluate image quality.One radiologist with more than 5 years of clinical experience and another one with 2 years of clinical experience scored the image quality.The results were analyzed using SPSS software paired t test.Results:There is no statistical difference in overall image quality,bile duct dilatation and pancreatic duct dilatation display on both conventional MRCP and CS-MRCP(P>0.05).The scores of dilated bile ducts are higher than the overall image quality score and pancreatic duct dilatation score.There was no statistical difference in the image scores of bile duct dilatation caused by stones and bile duct dilatation caused by masses.Conclusions:There is no significant difference in image quality between compressed sensing cholangiopancreatography and conventional cholangiopancreatography,however,compressed sensing cholangiopancreatography can effectively shorten the imaging time and reduce respiratory motion artifacts.
