CT灌肠(CT enteroclysis,CT-E)为小肠疾病的一种检查方法,能清晰显示肠内结构,使肠管分段成像,通过重组可显示肠外病变。由于多层螺旋CT扫描速度快并具有扫描后重组的能力,CT灌肠已成为传统灌肠的延伸及小肠的CT检查方法[1]。〗技术CT灌肠操作与钡剂灌肠类似,如病人准备、术前 CT Enteroclysis (CT-E) is a test for small bowel disease that clearly shows the structure of the intestine and allows the intestine to be sectionally imaged to reveal parenchymal lesions by recombination. Due to the high speed of multi-slice spiral CT scanning and the ability to perform post-scan recombination, CT enema has become an extension of traditional enema and CT examination of small intestine [1]. Technology CT enema operation and barium enema similar, such as patient preparation, preoperative
