Radiation protection issues in PET/CT have been addressed adequately with significant progress being made in reducing occupational radiation doses in PET/CT facilities. Applied measurement techniques and variation in work practices increase the...
Abstract:
The number of installed PET/CT scanners is increasing and this will increase the workload which would result in higher extremity radiation dose. Thus, an effort should be made to review the recent practice of radiation protection in PET/...
Abstract
Accurate dose rate estimates is important for radiation protection specialists conducting risk assessments and performing dose reconstruction in cases of accidental exposures.
Objectives: The objectives of this work was to experimentally...
The number of installed PET/CT scanners is increasing leading to an increased workload which could result in higher radiation dose received by nuclear medicine workers responsible for conducting the imaging studies in clinical environment. An effort...
Introduction
Variations in FDG biodistribution and organ uptake levels are patient specific and vary with organs sizes and disease types. Radiation self-attenuation and scatter characteristics are assumed to be patient specific and may have...
The aim of this study was to test the feasibility of using Gafchromic XR-QA2 films in the measurements of patient entrance surface dose (ESD) during the micturating cystourethrogram (MCUG) examination in paediatric patients. Radiochromic films were...
The aim of the study was to measure the actual dose at 1 m from the patients per unit activity with the aim of providing a more accurate prediction of the dose levels around radioiodine patients in the hospital, as well as to compare our results...
Over the past decade, the number of positron emission tomography/computed tomography (PET/CT) imaging procedures has increased substantially. This imaging technique provides accurate functional and anatomical information, particularly for...
The calculated dose rate from the radioiodine therapy patient should normally include a factor accounting for the attenuation and scatter of patient body tissues. The attenuation factor is currently neglected, and not applied in operational...
Accurate dose rate estimates is important for radiation protection specialists conducting risk assessments and performing dose reconstruction in cases of accidental exposures.
Objectives: The objectives of this work was to experimentally evaluate...
The objectives of this work were to estimate the amount of fluorine-18 fluorodeoxyglucose (F-FDG) excreted (AFE) in the patient urine during the uptake phase as percentage of the injected activity and to examine the effect of blood glucose levels (...
