Computed Tomography (CT) was first introduced as a medical device in the 1970’s, and has since become a ubiquitous imaging tool. Recent technical advances including faster scan times, improved spatial resolution, and advanced multi-planar reconstruction techniques have led to the application of CT for the evaluation of numerous anatomic abnormalities and disease processes. Several strategies to reduce CT-associated radiation have been attempted. One strategy is to vet CT as the appropriate diagnostic test with preferential use of other imaging modalities such as ultrasound and MRI when able, particularly in pediatrics, and to limit the CT examination to the anatomic area in question. A second strategy involves optimizing scanning parameters (such as kVp, pitch and mA) in order to reduce exposure in all patient populations. If CT is felt to be necessary, applying optimized technical parameters and limiting the scan area can substantially reduce radiation exposure and result in dose reductions as high as 65%. These important techniques are described in this book.
