Computed tomographic (CT) enterography is an emerging alternative to traditional fluoroscopy for the assessment of disorders of the small bowel. The greatly improved spatial and temporal resolution provided by multidetector CT scanners, combined with good luminal distention provided by negative oral contrast agents and with good bowel wall visualization, have made CT enterography the main imaging modality not only for investigating proved or suspected inflammatory bowel disease but also for detecting occult gastrointestinal tract bleeding, small bowel neoplasms, and mesenteric ischemia. CT enterography is particularly useful for differentiating between active and fibrotic bowel strictures in patients with Crohn disease, thus enabling selection of the most appropriate treatment (medical management or intervention) for an improved outcome. CT enterography allows excellent visualization of the entire thickness of the bowel wall and depicts extraenteric involvement as well, providing more detailed and comprehensive information about the extent and severity of the disease process.
计算机断层扫描（CT）肠造影术是一种新兴的替代传统透视检查小肠疾病的方法。多排螺旋 CT 扫描仪提供的大大提高的空间和时间分辨率，结合阴性口服对比剂提供的良好内腔扩张和良好的肠壁可视化效果，使 CT 肠造影术不仅成为研究已证实或疑似炎症性肠病的主要成像方式，也成为检测隐匿性胃肠道出血、小肠肿瘤和肠系膜缺血的主要成像方式。CT 肠造影术对于区分克罗恩病患者的活动性和纤维性肠狭窄特别有用，从而能够选择最合适的治疗方法（药物治疗或干预）以获得更好的结果。CT 肠造影术可以极好地显示肠壁的全部厚度，并描绘肠外受累情况，提供有关疾病过程的范围和严重程度的更详细和全面的信息。
