Abstract
Technical advancements in computed tomography (CT) have revolutionized the field of medical imaging. Originally invented for the sole purpose of head imaging, current generation CT systems are able of performing full-body examinations within seconds. Modern CT hardware, innovative image reconstruction techniques and improvements in computing power have resulted in a steady increase in the number of CT examinations in the last decades. Combined with efforts to reduce associated radiation exposure, CT imaging has emerged as the workhorse of modern-day (neuro-)radiology, especially in emergency setting. The following chapter provides an overview of the technical principles and modalities of CT as well as radiation exposure and associated risks.
