State of the art: technologies for computed tomography dose reduction

Review Article


The utilization of computed tomography (CT) in the emergency department has grown rapidly in the last decade, driven by strong evidence supporting its effectiveness in the rapid diagnosis of an increasing range of diseases. Concerns have been raised about potential cancer induction caused by the increased use of CT and the high radiation dose associated with some multidetector row CT examinations. Recent research into protocol design and new CT scanner technologies enable high-quality examinations to be performed with a significant reduction in radiation dose. These advances are discussed, with emphasis on their application to emergency radiology.
