目的 探讨螺旋CT胆道造影 (SCTcholangiography ,SCTC)的技术及其临床应用价值。材料与方法 3 0例怀疑胆系疾病者作螺旋CT胆道造影 ,11例同时进行MRC检查。图像用三维 ( 3D)最大信号强度投影 (MIP)及表面阴影显示 (SSD)后处理。结果 2 5例胆道显影 ,其血清总胆红素均 <5 1.3 μmol/L( 17.1μmol/L =1mg/dl)。三维重建图像清晰显示胆道解剖结构、梗阻部位或病变形态 ,弥补了横断面图像的不足 ,提高了诊断能力。与MRC比较可显示更多胆道细节。结论 SCTC在轻中度梗阻性黄疸病例胆道显影良好 ,3D图像可满意显示胆道解剖结构 ,提高了对胆道疾病的诊断能力。
Objective To investigate the technique and clinical value of spiral CT CT cholangiography (SCTC). Materials and Methods Thirty patients with suspected gallbladder disease underwent spiral CT cholangiography, while 11 patients underwent MRC at the same time. The image is processed with three-dimensional (3D) maximum signal intensity projection (MIP) and surface shadow display (SSD). Results Serum total bilirubin was found to be less than 5 1.3 μmol / L (17.1 μmol / L = 1 mg / dl) in 25 cases of biliary tract imaging. Three-dimensional reconstruction of the image clearly shows the biliary anatomy, obstruction or lesion morphology to make up for the lack of cross-sectional images and improve the diagnostic capabilities. Compare with MRC to show more details of biliary tract. Conclusions SCTC develops well in the biliary tract of mild to moderate obstructive jaundice. The 3D images can satisfactorily display the biliary anatomy and improve the diagnostic ability of the biliary tract.
