Diagnostic Reference Levels of CT Radiation Dose in Whole-Body PET/CT.
UNLABELLED The role of CT in PET/CT imaging includes acquisition techniques for diagnostic, anatomic localization, and attenuation correction purposes. Diagnostic reference levels of the volumetric CT dose index (CTDIvol) are available for dedicated CT procedures on selected body regions, but similar reference levels for whole-body CT used in PET/CT examinations are limited. This work reports C...
متن کاملLocal Diagnostic Reference Levels for Some Common Diagnostic X-Ray Examinations In Sabzevar County of Iran
Introduction: Diagnostic reference level (DRL) is a useful tool for the promotion of optimization. The national DRLs (NDRLs) are useful, brief, and robust guidelines for optimizing radiation protection in a country. The aim of this study was to extract the local DRLs (LDRLs) for some common radiologic examination in Sabzevar county. Materials and Methods: There are eight radiology departments ...
متن کاملAssessment and evaluation of patient doses in adult common CT examinations towards establishing national diagnostic reference levels
Background: Patient radiation doses from computed tomography (CT) are increasing due to the number of CT examinations performed every day. The aim of this study was assess and evaluate patient radiation doses for adult’s common CT examinations to derive local diagnostic guidance levels for common CT examinations. Materials and Methods: Volume and weighted computed tomography dose index (C...
