Dosimetry Calculations of Radiopharmaceuticals
Abstract. The goal of this project is to determine the absorbed dose of radiation to a patient using 99mTc-MAA as a tracer for a lung scan using the MIRD formula accounting only for the radiation dose contributed by the target organ. The radiation dose for other organs to the target organ is considered negligible as the uptake of 99mTc-MAA from other organs is less than 1%. In addition to calcu...
متن کاملNew calculations for internal dosimetry of beta-emitting radiopharmaceuticals.
The calculation of absorbed dose from internally incorporated radionuclides is based on the so-called specific absorbed fractions (SAFs) which represent the fraction of energy emitted in a given source region that is absorbed per unit mass in a specific target organ. Until recently, photon SAFs were calculated using MIRD-type mathematical phantoms. For electrons, the energy released was assumed...
متن کاملUncertainties in internal dose calculations for radiopharmaceuticals.
This paper presents a systematic analysis of the inherent uncertainty in internal dose calculations for radiopharmaceuticals. A generic equation for internal dose is presented, and the uncertainty in each of the individual terms is analyzed, with the relative uncertainty of all terms compared. The combined uncertainties in most radiopharmaceutical dose estimates will be typically at least a fac...
متن کاملBreast milk excretion of radiopharmaceuticals: mechanisms, findings, and radiation dosimetry.
The excretion of radiopharmaceuticals in breast milk is studied to understand excretion mechanisms and to determine recommended breast feeding interruption times for many compounds based on the radiation absorbed dose estimated. A literature review is summarized, providing information on breast milk excretion of many radiopharmaceuticals, including the observed fractions of administered activit...
متن کاملRadiopharmaceuticals for nuclear cardiology: radiation dosimetry, uncertainties, and risk.
UNLABELLED The technical basis for the dose estimates for several radiopharmaceuticals used in nuclear cardiology is reviewed, and cases in which uncertainty has been encountered in the dosimetry of an agent are discussed. Also discussed is the issue of uncertainties in radiation dose estimates and how to compare the relative risks of studies. METHODS Radiation dose estimates (organ absorbed ...
