CT检查是一种新的X线诊断法,其诊断价值受到高度评价,而使用造影剂又可进一步提高CT的诊断率,故其应用日益增加,副作用问题也随之而来。作者近三年共作CF检查213例,其中使用造影剂者130例(约占60％,年龄9～75岁)。使用水溶性有机碘造影剂:65％泛影葡胺(Angiografin)100ml,60％碘酞葡胺(Conray)100ml。使用前宜先作:(1)询问有无碘过敏史。肾功能不全、重度甲状腺机能亢进、多发性骨髓瘤、严重心功能不全、重度肺结核、急性胰腺炎者忌用造影剂。有药物过敏史和过敏性体质者需先作碘过敏反应试验。(2)所有造影病例原则上均应行碘
CT examination is a new X-ray diagnostic method, its diagnostic value is highly valued, and the use of contrast agents can further improve the diagnostic rate of CT, so its application is increasing, side effects problems also follow. The author made a total of 213 CF examinations in the past three years, of whom 130 were used contrast media (about 60%, aged 9-75 years). Water-soluble organic iodine contrast media were used: 65% Angiografin 100 ml, 60% Conray 100 ml. Before use should be made first: (1) asked if there is no history of iodine allergy. Renal insufficiency, severe hyperthyroidism, multiple myeloma, severe heart failure, severe pulmonary tuberculosis, acute pancreatitis were hanged contrast agent. A history of drug allergies and allergic constitution need to be iodine allergic reaction test. (2) All cases of contrast should be iodine in principle
