The availability of the new low osmolality contrast agents during the last few years has necessitated a reconsideration of which is the most appropriate contrast agent to utilize in the gastrointestinal (GI) tract. There are some clinical situations in which these new agents have become the contrast media of choice (e.g., evaluation of suspected necrotizing enterocolitis, evaluation of suspected bowel perforation). There are many other clinical situations in which one needs to weigh the potential benefits of the new agents against significantly increased costs. This report reviews in detail the available contrast agents for studying the GI tract and outlines the advantages and disadvantages of each agent. The new agents are compared with existing agents such as barium and the hypertonic water soluble agents (e.g., gastrografin, hypaque, conray, etc.). Guidelines for the use of each agent are presented.
在过去几年中，新型低渗性造影剂的出现使得有必要重新考虑在胃肠道（GI）中使用哪种最合适的造影剂。在一些临床情况下，这些新型造影剂已成为首选的造影剂（例如，评估疑似坏死性小肠结肠炎、评估疑似肠穿孔）。在许多其他临床情况下，人们需要权衡新型造影剂的潜在益处与显著增加的成本。本报告详细回顾了用于研究胃肠道的现有造影剂，并概述了每种造影剂的优缺点。将新型造影剂与钡剂和高渗水溶性造影剂（例如，泛影葡胺、碘海醇、康瑞等）等现有造影剂进行了比较。还给出了每种造影剂的使用指南。
