Radiation dosimetry of 18F-FDG PET/CT: incorporating exam-specific parameters in dose estimates

Radiation dosimetry of 18F-FDG PET/CT: incorporating exam-specific parameters in dose estimates

BACKGROUND Whole body fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) is the standard of care in oncologic diagnosis and staging, and patient radiation dose must be well understood to balance exam benefits with the risk from radiation exposure. Although reference PET/CT patient doses are available, the potential for widely varying total dose prompts eval...

18F-FDG PET in pregnancy and fetal radiation dose estimates.

UNLABELLED The purpose of this study was to estimate the fetal radiation exposure resulting from (18)F-FDG PET procedures performed in pregnant patients with malignancies. METHODS Five pregnant patients with a biopsy-proven diagnosis of malignancy who underwent (18)F-FDG PET studies were retrospectively reviewed. All patients underwent PET-only studies (and not PET/CT studies) with a reduced ...

Reduced-dose [F]-FDG PETCT scanning with current generation PETCT systems

Evaluation of Radiation Exposure to Staff and Environment Dose from [18F]-FDG in PET/CT and Cyclotron Center using Thermoluminescent Dosimetry

Background: PET/CT imaging using [18F]-FDG is utilized in clinical oncology for tumor detecting, staging and responding to therapy procedures. Essential consideration must be taken for radiation staff due to high gamma radiation in PET/CT and cyclotron center. The aim of this study was to assess the staff exposure regarding whole body and organ dose and to evaluate environment dose in PET/CT an...

FDG PETCT in colorectal cancer

Colorectal cancer represents the second most common malignancy worldwide, with approximately one million newly diagnosed cases each year, and is the fourth leading cause of cancer mortality. This article provides an overview of the role of FDG (fluorodeoxyglucose) PET (positron emission tomography) CT (computed tomography) for assessment in patients with colorectal cancer. A summary of key lear...
