【摘要】：目的比较三维可变翻转角的快速自旋回波(3D-SPACE)与三维传统快速自旋回波(3D-TSE)及二维快速自旋回波(2D-TSE)序列磁共振胰胆管显影(MRCP)用于显示胆囊及胆总管结石的图像质量。方法采用呼吸导航的3D-SPACE序列和传统3D-TSE序列及屏气采集的2D-TSE对10名健康志愿者(对照组)和22例胆道结石患者(患者组)行MRCP,比较3种成像方法的图像采集时间、胆总管CNR、胰胆管影像质量、及对结石的显示情况。结果在患者组及对照组中,3D-SPACE胆总管CNR均明显高于传统2D-TSE、3D-TSE序列(P均0.05);3D-SPACE序列图像质量评分、运动伪影、胆总管、左右肝内胆管、主胰管评分均明显高于2D-TSE、3D-TSE序列(P均0.05);3D-SPACE序列影像采集时间均较传统3D-TSE序列减少,患者组减少(20.90±0.21)%,对照组减少(23.09±0.12)%。2D-TSE序列用时最短,SPACE序列原始像对胆囊及胆总管结石显示最优。结论相比于2D-TSE-MRCP、3D-TSE-MRCP序列,3D-SPACEMRCP影像质量更好,其原始影像更适用于显示胆囊和胆管结石,但图像采集时间长于2D-TSE。
[Abstract]:Objective to compare 3D-SPACE-3D-SPACE-3D-SPACE-3D-SPACE-3D-SPACE-3D-SPACE-3D-TSE-3D-TSE-3D-TSE-3D-SPACE-3D-SPACE-3D-SPACE-3D-SPACE-3D-TSE-2D-TSE-MRCPC to display the quality of cholecystolithiasis and choledocholithiasis. Methods MRCPs were performed in 10 healthy volunteers (control group) and 22 patients with cholelithiasis by using 3D-Space sequence of respiratory navigation and 3D-TSE sequence of traditional 3D-TSE sequence and 2D-TSE sequence of breath-holding. The time of image acquisition by three imaging methods was compared. Results CNR of common bile duct, cholangiopancreatopancreatic cholangiopancreatic duct and cholelithiasis in patients and control group were significantly higher than those in traditional 2D-TSE 3D-TSE sequence (P 0.05), motion artifacts, common bile duct, left and right intrahepatic bile duct. The score of main pancreatic duct was significantly higher than that of 2D-TSE 3D-TSE sequence (P < 0.05) and the time of 3D-Space image acquisition was lower than that of traditional 3D-TSE sequence. In the control group, the reduction of 20.90 卤0.21% and the reduction of 23.09 卤0.12% in the control group were found to be the best in displaying cholecystolithiasis and choledocholithiasis with the shortest space sequence. Conclusion compared with the 2D-TSE-MRCP 3D-TSE-MRCP sequence, 3D-SPACEMRCP is better than the 2D-TSE-MRCP sequence, and the original image is more suitable for displaying cholecystolithiasis and cholelithiasis. But the time of image acquisition is longer than that of 2D-TSE.
