Adverse reactions to iodinated and gadolinium-based contrast agents occur at an incidence of less than 1%. Although the exact pathophysiologic mechanisms are not completely understood, the treatment regimens are well accepted. Skin testing may be helpful in patients with a history of severe allergiclike reaction to aid in the selection of alternative contrast agents. Premedication should only be used for a history of allergiclike reaction. Imaging team members should be familiar with signs and symptoms of contrast reactions to allow for prompt assessment and treatment. A plan of action should be in place for contrast reactions and rehearsed regularly.
碘造影剂和钆基造影剂的不良反应发生率低于1%。尽管确切的病理生理机制尚未完全了解，但治疗方案已被广泛接受。对于有严重过敏样反应病史的患者，皮肤试验可能有助于选择替代造影剂。预处理仅应用于有过敏样反应病史的患者。影像团队成员应熟悉造影剂反应的体征和症状，以便及时评估和治疗。应制定造影剂反应的行动计划并定期演练。
