The presentations and discussions provide each of the clinicians' experience with current literature on the clinical applications of CTA.
In July of 2003, I served as the moderator for a 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 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. Along with the additional resources of the
suggested readings and protocols, 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 www.ctisus.com.
I would like to thank Amersham Health 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.
