To overcome the problem of inadequate mixing of gastrointestinal (GI) tract contents with conventional high-density oral contrast agents in abdominal computed tomography (CT), a flavored 12.5% corn oil emulsion (COE) was tested as an oral contrast agent in 62 patients. The results were compared with those obtained from 105 patients who received high-density oral contrast agents. A simple patient preparation regimen for the COE was developed, which appears to be reasonably well tolerated by the patients and yields diagnostic studies comparable to those obtained with conventional agents. Use of the COE resulted in consistent discrimination of the GI tract and depiction of the GI wall. Preliminary data suggest that it may be particularly useful for CT evaluation of the stomach, duodenum, and pancreas; in patients suspected of having solid tumors; and in thin people.
为克服腹部计算机断层扫描（CT）中胃肠道（GI）内容物与传统高密度口服造影剂混合不充分的问题，对一种调味的12.5%玉米油乳剂（COE）作为口服造影剂在62例患者中进行了测试。将结果与105例接受高密度口服造影剂的患者的结果进行比较。开发了一种简单的COE患者准备方案，患者对此似乎耐受性良好，且所获得的诊断研究结果与使用传统造影剂相当。使用COE可对胃肠道进行持续区分并显示胃肠道壁。初步数据表明，它可能对胃、十二指肠和胰腺的CT评估特别有用；对疑似患有实体瘤的患者；以及对体型瘦的人。
