随着放射诊断技术的发展,血管造影、电算体层、介入性放射学等使用水溶性碘造影剂的机会日益增加,用量亦大;因之,对其不良反应的探索是近年热衷的课题。一、造影剂的分类及体内过程程:目前使用的主要是各种水溶性含碘的有机酸衍生物——三碘苯甲酸衍生物。按排泄途径分为经肾排泄和经肝排泄两类。前者用于排泄
With the development of diagnostic radiology, the opportunities for using water-soluble iodine contrast agents, such as angiography, computed tomography, and interventional radiology, are increasing, and the dosage is also large. Therefore, the exploration of adverse reactions has been a subject of keen interest in recent years . First, the classification of contrast agents and process in vivo process: At present, the main use is a variety of water-soluble iodine-containing organic acid derivatives - triiodobenzoic acid derivatives. Divided by excretion by the renal excretion and excretion by the two types of liver. The former for excretion
