Modern medicine cannot be imagined without the diagnostic capabilities of computed
tomography (CT). Although the past decade witnessed a tremendous increase in scan …

Although radiation dose in computed tomography (CT) decreased and CT became safer
examinations than before, CT is the most significant source of the medical radiation …

Background Despite the prevalence of chest CT in the clinic, concerns about unoptimized
protocols delivering high radiation doses to patients still remain. This study aimed to assess …

Background Radiation dose in computed tomography (CT) has become a topic of high
interest due to the increasing numbers of CT examinations performed worldwide. Hence …

Fast chest CT scans with high-pitch factors are effective to reduce motion artifacts, but the
over-ranging effect may increase harmful radiation exposure to organs which are located …

Objectives Compare incidence of over-scanning in chest CT among six hospitals and impact
on effective and organ effective radiation dose. Methods Scout images of 600 chest CTs …

Introduction The purpose of this study was to develop a convolutional neural network (CNN)
to determine the extent of over-scanning in the Z-direction associated with lung computed …

Objectives To evaluate the radiation dose of the main body CT examinations performed
routinely in four regional diagnostic centres, the specific contribution of radiologists and …

During computed tomography (CT) examinations, radio-sensitive organs located outside the
field of view (FOV) are usually exposed to radiation caused by both direct and scattered X …

Purpose To assess the variability of radiation dose exposure in patients affected by
lymphoma undergoing repeat CT (computed tomography) examinations and to evaluate the …
