A great deal of work has been done reconstructing doses from Nevada Test Site fallout, yet the unique exposures of Native American communities continue to be neglected. It is possible to estimate the exposures of these communities through a process of collaborative information gathering and analysis. This paper builds on a previous exercise that demonstrated the substantial doses received throu...

Background: Application of Dose-area product (DAP) quantity has been increased in the clinical practice. DAP is relatively easy to measure. DAP has been shown to correlate well with the total energy imparted to the patient, which is related to the effective dose. Material and Methods: In this study, measurements of DAP were carried out in a sample of 421 adult patients who underwent convention...

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 ...

This report provides estimates of the external radiation exposure and whole body effective dose received by residents of the continental U.S. during the period 1953-2000 from nuclear weapons tests. Doses were calculated for tests carried out in the Pacific by the U.S. and U.K. and by the U.S.S.R. at various sites in the former Soviet Union during the years 1952-62. Estimates are given on a coun...

The primary study objective was to assess radiation doses using a modified form of the Imaging Performance Assessment of Computed Tomography (CT) scanner (ImPACT) patient dosimetry for cardiac applications on an Aquilion ONE ViSION Edition scanner, including the Ca score, target computed tomography angiography (CTA), prospective CTA, continuous CTA/cardiac function analysis (CFA), and CTA/CFA m...

UNLABELLED Absorbed-dose calculations provide a scientific basis for evaluating the biologic effects associated with administered radiopharmaceuticals. In cancer therapy, radiation dosimetry supports treatment planning, dose-response analyses, predictions of therapy effectiveness, and completeness of patient medical records. In this study, we evaluated the organ radiation absorbed doses from in...

The exposure estimates used to date for the analysis of lung cancer mortality in the Colorado Plateau Uranium Miners cohort were developed from radon progeny measurements taken in mines beginning in 1951. Since uranium miners were often exposed over long periods of time and since mines were not continuously monitored, much extrapolation and/or interpolation of measured dose-rates was needed in ...

OBJECTIVE The purpose of this study is to show how to calculate effective dose in CT using size-specific dose estimates and to correct the current method using dose-length product (DLP). MATERIALS AND METHODS Data were analyzed from 352 chest and 241 abdominopelvic CT images. Size-specific dose estimate was used as a surrogate for organ dose in the chest and abdominopelvic regions. Organ dose...

Three models for the biodistribution and dosimetry of 82Rb-chloride were reviewed and a proposal is made for the best dosimetry for this agent to be adopted. Data from three proposed biokinetic models for 82Rb-chloride were used to calculate dose estimates for the compound, and the results were compared. The blood content-based model was found to produce dose estimates that were considered to b...
