Abstract
The principles of protecting the subject undergoing investigation by radiation are clear and well known: it is the responsibility of all radiological services to ensure the information required for the clinical management of the patient is obtained with the lowest practicable exposure to radiation. Within this clear objective, however, medical investigation operates in a constantly changing scenario influenced by increasing knowledge of disease processes and advancing technological development. This syndrome ensures that as time passes differing objectives and concerns come to the fore. Over the past few years the emergence of multidetector computed tomography (MDCT) has posed new challenges in radiological protection, to the extent that some now claim that this represents today’s greatest single challenge in clinical radiation protection. This book expounds the challenges posed by MDCT to scientists and physicians and in this chapter we provide an introduction to the main themes which are of concern.
