什么是离子型造影剂，什么是非离子型造影剂，二者之间有何差别，造影剂各种不良反应的本质是什么，这些都是当前普遍关注的问题，现简单总结如下。离子型和非离子型造影剂在诸多方面的差别是很大的，其根本原因是由于离子型造影剂分子在溶液中被电离成带正、负电荷的离子... What is the ionic contrast agent, what is the non-ionic contrast agent, what is the difference between the two, what is the nature of the adverse effects of contrast agents, these are the current general concern, are briefly summarized as follows. Ion and non-ionic contrast agents in many ways the difference is great, the fundamental reason is that ionic contrast agent molecules are ionized in solution into positively and negatively charged ions ...
