Technetium-99m diethylene triamine pentaacetic acid (Tc-99m DTPA) renal dynamic scintigraphy is a widely used imaging technique that evaluates renal function of patients with extrarenal abnormalities, but its clinical value in potentially offering us information on proliferation of liposarcoma has not yet been reported. (netlify.app)
This safety record is attributable to the very small fraction of the pulmonary vasculature that is occluded by the typical injection of Tc-MAA. (netlify.app)
Initial elevated uptake in kidneys decreased rapidly, and by 3 h post injection, the renal uptake (13 ± 3%ID/g) did not differ significantly from tumor uptake (9 ± 3%ID/g). (bvsalud.org)
100,0002
The typical adult dose for a lung imaging study is 40-150 Megabecquerels (1-4 mCi) (containing between 100,000 - 200,000 albumin particles). (wikipedia.org)
2020-08-19 Tc-99m MAA is enormous: the adverse reaction rate in the US for Tc-99m MAA is approximately 2/100,000 injections, an outstanding track record. (netlify.app)
Renal2
Characteristics photon energy: 140 KeV physical half life: 6 hours biological half life: 2-3 hours normal distribution: lungs, Tc-99m MAG3 (mercaptoacetyltriglycine) is one of the technetiumradiopharmaceuticals used in renal imaging. (netlify.app)
Due to favorable energy and dosimetric characteristics, MAG3 radiolabeled with technetium has replaced the iodide-131 Hippuran for the study of renal function (tubular secretion physiology) 7. (netlify.app)
Blood1
Upon intravenous administration, skeletal uptake of technetium Tc 99m methylene diphosphonate occurs as a function of skeletal blood flow and … Supply of Technetium-99m (Tc-99m) is a just-in-time activity requiring continuous production in a complicated and aging supply chain that combines a mix of governmental and commercial entities.

Normal1
After being allowed to react at room temperature for 15 minutes to ensure maximum labeling of the human albumin with 99mTc, the kit can then be diluted with sterile normal saline as needed. (wikipedia.org)
Radioactive1
A radioactive isotope of technetium having a half-life of 6 hr, in which the "m" means that it is a metastable isotope. (mhmedical.com)
Lungs2
Intravenous administration of Ga-68-particles to rats resulted in an average radiotracer uptake after 20 minutes, of more than 92% in the lungs, and less than 5% in the liver plus spleen or in the carcass. (atlasofscience.org)
The Ga-68 scan in Figure 1 clearly showed the lungs, it was superior to a Tc-99m-aggregated-albumin rat scan performed on another occasion. (atlasofscience.org)
Particles3
It consists of a sterile aqueous suspension of Technetium-99m (99mTc) labeled to human albumin aggregate particles. (wikipedia.org)
No less than 90% of the radioactivity present in the product must be tagged to albumin particles. (wikipedia.org)
The typical adult dose for a lung imaging study is 40-150 Megabecquerels (1-4 mCi) (containing between 100,000 - 200,000 albumin particles). (wikipedia.org)
Perfusion1
99m Tc is used in nuclear medicine for a wide variety of diagnostic tests and imaging studies, e.g., myocardial perfusion scans, bone scans, and V/Q scans. (mhmedical.com)
Nuclear medicine2
Technetium 99mTc albumin aggregated (99mTc-MAA) is an injectable radiopharmaceutical used in nuclear medicine. (wikipedia.org)
Its isotope, technetium-99, is used in nuclear medicine for a wide variety of diagnostic tests. (mhmedical.com)
Diagnostic2
Absence of uptake of the molecule by the brain is diagnostic of brain death. (mhmedical.com)
The low uptake by non-target organs did not interfere with the diagnostic quality, and there was pronounced lung uptake against a low background. (atlasofscience.org)
