摘　　要：目的:探讨影像学在小儿肠套叠诊断、治疗中的应用。方法:回顾性总结1096例肠套叠患儿B超、数字化X线机、CT及电子结肠镜影像学特点、诊断价值和治疗的效果。结果:肠套叠B超以"同心圆征"及"套筒征"为典型特征,诊断准确率99.5%。数字化X线机以"半球征"或"宫颈征"为典型特征,诊断准确率100%。二者准确率无显著性差异。CT诊断肠套叠可靠,尤其是小肠套叠更佳,电子结肠镜可以直观套叠头部。以空气为整复介质,整复率93.2%;空气灌肠失败74例均手术治愈。结论:利用B超、数字化X线机诊治肠套叠辅以手术,是儿童诊治肠套叠的主要方法。Objective：To study the value of imaging in the diagnosis and treatment of intussusception in children.Methods：The imaging data of 1 096cases children of intussusception on diagnosis and treatment by B-ultrasound,digitised X-ray,CT,and electronic colonoscopy were retrospectively studied.Results：The diagnosis rate of B mode ultrasonography was 99.5%in this group.The typical characteristics appeared as＂multiple concentric rings＂and＂sleeve sign＂.The diagnosis rate of digital X-ray was 100%and the typical characteristics appeared as＂hemisphere sign＂and ＂cervix sign＂.There were no significant difference between the two groups in diagnosis rate.The reduction rate of air-enema treatment was 93.2%.All media of reduction were air.Seventy-four unsuccessful cases of air-enema treatment were all cured clinically by operation.Electronic colonoscopy could observe immediately the head of intussusception.The diagnosis of intussusception was reliable by CT,especially to the small intestine intussusception.Conclusion：The diagnosis and treatment of intussusception by B-ultrasound,digitised X-ray and open operation are the main methods in children.
