Given the uniform use of low osmolar and iso-osmolar contrast media agents, life-threatening contrast media-related reactions have become relatively infrequent. However, when an unpredictable reaction occurs unexpectedly, radiologists and CT support staff are frequently ill-prepared to manage—often making irreversible mistakes with potentially grave patient consequences and outcomes, including death. This Online Course will address common conundrums and pitfalls for radiologists managing unexpected contrast media reactions in the CT suite.

Learning Outcomes

After completing this course, the learner should be able to:

• describe the severity of contrast reactions and their appropriate treatment
• discuss how to recognize and manage iodine mumps sialadenitis
• apply practice tips for premedication in unusual situations including patients already on corticosteroids or missed doses
• specify the differences between and indications for elective versus accelerated premedication regimens
