Advances in CT technology particularly the multiple-row detector scanners have
presented new opportunities for improved patient imaging and throughput. With state of
the art CT scanners it is now possible to image the whole body in less than a minute.
This has led to newer clinical applications but also at times resulted in excessive use of
CT. A recent flurry of articles both in literature and in news media has drawn attention to
radiation dose from CT exams. The notification from FDA emphasizes the importance of
reducing radiation risk from CT for pediatrics and small adults. Since the use of CT in
medicine cannot be curtailed, it is desirable to minimize radiation dose from CT exams.
The goal of this symposium is to discuss methods to reduce CT dose without
compromising the image quality and ultimately the patient care. Four speakers, Elliot
Fishman, Edward Nickoloff, Bryan Westerman and Stanley Fox will discuss different
perspectives on to how to achieve this goal, which will be followed by question and
answer session.
