【摘要】 目的探讨肝吸虫病的多层螺旋CT表现和诊断价值。方法回顾性分析l69例肝吸虫病的多层螺旋CT表现。结果肝内末梢胆管扩张159例(94.1%);末梢型扩张的112例增强CT,平扫显示不清而增强门静脉期显示清晰的69例(61.6%);肝内胆管轻度扩张123例(72.8%),均为薄层重建后明确;末梢胆管小结石或钙化63例(37.3%)。结论多层螺旋CT增强+MPR后处理技术能显著提高末梢胆管扩张检出率;肝吸虫疫区,发现肝末梢胆管扩张,应首先考虑肝吸虫病;当合并末梢胆管小结石或钙化,可进一步作出判断。更多还原

【Abstract】 Objective To study the MSCT features of clonorchiasis and diagonstic value of MSCT.Methods 169 patients with clonorchiasis MSCT features were analyzed.Results Intrahepatic peripheral bile duct were dilated in 159 cases(94.1%);In case of peripheral bile duct dilatation in 112 patients had CT contrast scanning,which plain scan display is unclear,and the portal venous phase contrast scanning can display clear in 69 cases(61.6%);Mild dilatation of the intrahepatic bile duct in 123 cases(72.8%),using the MSCT thin layer reconstruction makes it clear display;Distal bile duct calculus or calcification in 63 cases(37.3%).Conclusion MSCT contrast scanning + MPR post-processing technology to be able increased the detection rate of peripheral bile duct dilatation;In the epidemic area of clonorchiasis,CT features of dilatation of peripheral duct should be considered as caused by clonorchiasis;When combined with distal bile duct calculus or calcification,we can further judge.更多还原
