目的：探讨上腹 CT 检查是否口服及如何选择对比剂，对图像质量及诊断价值的影响。方法随机选取2013年12月～2014年5月间，90例上腹部 CT 检查者。采用以下4种方法：临床禁食、禁饮、急、重症患者，无需胃肠道准备，直接 CT 检查；普通患者服用阴性水对比剂；普通患者服用阳性碘对比剂；普通患者服用产气粉；CT 扫描后观察肝脏、胆囊、胃及十二指肠、胰腺、脾图像显示。结果未服组织结构对比差；服水、碘对比剂胃、十二指肠、胰头显示较好；服产气粉胃壁显示好、扩张充分。结论胃部疾患服用产气粉好；服用水、阳性碘对比剂胃、胰腺、腹膜后及十二指肠图像清晰对比度好；合理应用对比剂降低医患纠纷。

Objective To explore effect on image quality and diagnosis value for the abdomen CT examination of the ne‐cessity using oral contrast agents and how to select contrast agent .Methods During the period from December 2013 to May 2014 at authors'hospital ,ninety patients who underwent abdominal CT scan were randomly selected ,using the fol‐lowing four examination protocols ,i .e .,noncontrast CT scan for fasing or critical patients ,CT scan with water as gastro‐intestinal negative contrast agent ,CT scan with iodinated positive contrast medium ,and CT scan with oral administration of aerogenic powder as gastrointestinal negative contrast medium .The CT appearances of liver ,gall bladder ,stomach , duodenum ,spleen and pancreas were obeserved and analyzed after examination .Results The contrast of tissue structure was poor in the noncontrast group .While ,the groups with the administration of water or iodine contrast medium dis‐played well‐circumscribed stomach ,duodenum and the head of pancreas .Stomach was fully inflated and gastric wall was clearly shown in the aerogenic powder group .Conclusion Oral ingestion of aerogenic powder as contrast agent has advan‐tages in displaying gastric diseases .And stomach ,pancreas ,retroperitoneal space and duodenum can be better shown by using water or iodine contrast medium .Appropriate application of contrast agents can decrease the incidence of medical disputes .
