Program Summary

Often there is lack of knowledge amongst imaging professionals regarding IV contrast dynamics and the relationship between contrast injection, observed enhancement, and scan acquisition timing. The design of appropriate imaging protocols leads to effective and consistent cardiovascular exams; especially when applied to complex clinical scenarios.

This CME/CE accredited program will review contrast-saline dynamics and discuss rational protocol design for cardiac and vascular CT angiography. Effective cardiovascular imaging protocols, utilizing multiple CT injector platforms to achieve optimal imaging, will be reviewed. We invite you to join Dr. Richard Hallett for a comprehensive discussion and case study review of this important topic.

Following the presentation questions from the audience were addressed in a moderated Q&A session.

Educational Objectives

At the completion of this activity, participants should be able to:

  • Understand the relationship between bolus contrast media injection and observed enhancement.
  • Implement methods to design rational contrast injection / scan acquisition protocols.
  • Review various models of CT contrast injectors and discuss benefits, limitations, and injection protocol adjustments for each.
  • Apply customized contrast-saline injection / scan principles to complex cardiovascular disease cases.

No special educational preparation is required for this CME/CE activity!
