Factors affecting radiation exposure dose in nursing staff during (18)F-fluorodeoxyglucose positron emission tomography/computed tomography.
OBJECTIVES We evaluated factors associated with increased radiation exposure dose in nursing staff who assisted patients with (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography (PET)/computed tomography (CT) examinations. METHODS The Barthel Index and Mini-Mental State Examination (MMSE) score were obtained before PET/CT examinations in 193 patients (mean age ± SD, 77.7 ± 8.0 y...

The effect of fasting on Positron Emission Tomography (PET) imaging
As a nuclear approach, Positron Emission Tomography (PET) is a functional imaging technique which is based on the detection of gamma ray pairs emitted by a positron-emitting radionuclide. There are certain limitations to this technique such as normal tissue uptake. Therefore, it has been recommended that patients prepare before scanning. Fasting for a short while before PET imaging is an exampl...
متن کاملA Comparative Study of the Construction of Positron Emission Tomography/Computed Tomography Facilities in Three South African Hospitals
Introduction: Development of higher energy modalities such as positron emission tomography/computed tomography (PET/CT), has led to more complex shielding problems. This is due to several factors, such as the radiopharmaceutical relatively high-administered activity, high patient throughput, and high energies of 511 kilo-electron volt (keV) positron annihilation photon...
متن کاملBackground-Based Delineation of Internal Tumor Volumes on Static Positron Emission Tomography in a Phantom Study
Objective(s): Considering the fact that the standardized uptake value (SUV) of a normal lung tissue is expressed as x±SD, x+3×SD could be considered as the threshold value to outline the internal tumor volume (ITV) of a lung neoplasm. Methods: Three hollow models were filled with 55.0 kBq/mL fluorine18- fluorodeoxyglucose (18F-FDG) to represent tumors. The models were fixed to a barrel filled w...
