Safety and Efficacy of Computed Tomography: A broad perspective (CT Safety and Efficacy), Final report

Project ID: 2388


Radiologists are able to visualise any part of the human body in three dimensions with exceptional quality by using the latest generation of computed tomography (CT) scanners. However, the increasing use of CT scanners also causes growing concern about the associated exposure of patients to X-rays. Are all CT scans really necessary? Are up-to-date protocols used to keep the radiation exposure of patients to X-rays as low as possible? Are further improvements in CT scanner design and engineering possible? How can CT scans of children be improved? What is the radiation exposure from the latest CT scanners and modern acquisition protocols? Such questions are being raised in the medical community but also in the popular press.
This EU research project aimed at answering all these questions. To achieve it, a scientific consortium consisting of well-known radiologists and physicists of 10 leading organizations was established (see Section 4, 'The CT Safety and Efficacy consortium'). The individual know-how of the scientists covered many scientific sub-specialties, such as paediatric radiology, radiation measurements, and advanced computer simulations.
The project was designed around four major scientific challenges in computed tomography: justification of CT scans, optimisation of CT technology, the proper application of CT scans of children, and assessment of patient exposure to X-rays during CT scans.
