Evaluation of the dose received by women worker in the lung scan centers use 99mTC-MAA by experimental and simulation
One of the most important groups that can be exposed to nuclear radiation is pregnant women and their fetus. This group of people can be technicians at nuclear centers located in the patients undergoing treatment or nuclear medicine diagnostic centers. The purpose of the paper is to determine the rate of doses received by female technicians who are indirectly in the vicinity of nuclear radiatio...
متن کاملAbsent pulmonary uptake on 99mTc MAA perfusion lung scan due to severe right-to-left shunt.
c 5 XTRAPULMONARY accumulation of Tc macroaggregated albumin (MAA) is rarely een on perfusion lung scan, and has been reported n less than 4% of a study population of nearly 380 atients.1 It occurs when the agent bypasses the ungs due to a right-to-left (R-L) cardiac or pulonary shunt, when it is shunted to the portal vein efore reaching the right atrium and ventricle of he heart, and when the ...
متن کاملThree-dimensional fractal analysis of 99mTc-MAA SPECT images in chronic thromboembolic pulmonary hypertension for evaluation of response to balloon pulmonary angioplasty: association with pulmonary arterial pressure
OBJECTIVE Balloon pulmonary angioplasty (BPA) is used for inoperable chronic thromboembolic pulmonary hypertension (CTEPH), but its effect cannot be evaluated noninvasively. We devised a noninvasive quantitative index of response to BPA using three-dimensional fractal analysis (3D-FA) of technetium-99m-macroaggregated albumin (Tc-MAA) single-photon emission computed tomography (SPECT). PATIEN...
متن کاملPreclinical evaluation of 68Ga-MAA from commercial available 99mTc-MAA kit
99mTc-Macroaggregated Albumin (99mTc-MAA) has been used as a perfusion agent. This study described development of the 68Ga-MAA via commercially available kits from Pars-Isotopes Company as a 99mTc-MAA kit. 68Ge/68Ga generator was eluted with suprapure HCl (0.6 M, 6 mL) in 0.5 mL fractions. The two fractions with the highest 68GaCl3 activity were generally used for labeling purposes. After label...
