In March 2004, I served as the moderator for a second focus
group discussion on The Use of Contrast in CT Angiography
Applications. This distinguished panel of radiologists addressed
many issues regarding the use of contrast in clinical CTA
applications, including technical issues, as well as contrast and
imaging features that affect the selection of contrast media for
CTA applications. These presentations and panel discussions are
published in this special online supplement to
to share these important insights with the radiology community.
The discussion was designed to provide some clarification on
several issues, including:
- Which applications are best suited to the use of CTA?
- How can CTA be optimized?
- What is the role of contrast in CTA?
- Which contrast and acquisition protocols provide high-quality
- Which factors influence the decision of which type, volume,
and concentration of contrast to use?
The presentations and discussions provide each of the
clinicians' experience with current literature on the clinical
applications of CTA. These articles provide a great deal of
valuable information for radiologists planning to add CTA to their
practice, or those just beginning to perform these studies. More
information on CTA, including additional protocols, is available at
I would like to thank GE Healthcare for sponsoring the focus
group and these proceedings, as well as Anderson Publishing for the
arrangements and the publication. We would also like to thank all
the panelists for their time and effort discussing CTA applications
in great detail.
