摘要 目的探讨64排螺旋CT增强扫描在小肠Crohn病中的应用价值。方法对21例经病理证实的小肠Crohn病患者行MDCT平扫及增强扫描,并在ADW4.4工作站进行后处理,分析小肠Crohn病影像学特点并进行比较。结果21例小肠Crohn病共累及78个肠段:累及回肠远段24个,回肠中段20个,回肠近段、空肠远段和空肠中段分别为9、6、5个,累及回盲部9个,广泛累及结肠5个;21例患者均同时累及2组以上小肠且呈节段性分布。病变肠段平扫CT值平均为(38±4)HU,动脉期为(78±12)HU,门静脉期为(96±13)HU,差异有统计学意义(F=265.35,P〈0.01)。病变肠段平扫与动脉期和门静脉期CT值两两比较,差异均有统计学意义(P〈0.05)。动脉期与门静脉期比较差异无统计学意义(P〉0.05)。结论小肠Crohn病的影像学表现具有一定的特征性,MDCT增强扫描在小肠Crohn病诊断中具有重要的价值。
