is commonly reported. This work systematically reviewed published articles on adult …

Introduction Computed tomography (CT) dose optimization is an important issue in
radiography because CT is the largest contributor to medical radiation dose and its use is …

Purpose To retrospectively evaluate radiation optimization efforts over 4 years for three
computed tomography (CT) protocols and to determine institutional (local) diagnostic …

Purpose. To explore doses from common adult computed tomography (CT) examinations
and propose national diagnostic reference levels (nDRLs) for Nigeria. Materials and …

PURPOSE We aimed to obtain typical values for head, neck, chest, and abdominal
computed tomography (CT) examinations from routine patients in 2018, and to review our …

Objectives To compare institutional dose levels based on clinical indication and BMI class to
anatomy-based national DRLs (NDRLs) in chest and abdomen CT examinations and to …

Purpose The aim of this work was to evaluate the dosimetric impact of high-resolution thorax
CT during COVID-19 outbreak in the University Hospital of Parma. In two months we have …

Purpose To determine diagnostic reference ranges on the basis of the size of a pediatric
patient's chest and to develop a method to estimate computed tomographic (CT) scanner …

Background and aim Spiral computed tomography (CT) scans, which are considered a high-
contrast resolution, quick and cross-sectional imaging technique, have grown in popularity …

Indication-based national diagnostic reference levels (DRLs) for a few most common
paediatric computed tomography (CT) examinations are proposed. Patient dose data …
