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.
