MAA kits were prepared with a more reasonable amount of Tc-99m and yielded high radiochemical purity values in typical incubation times. Images have continued to be of high diagnostic quality. Conclusion: Tc-99m MAA used for lung transplant imaging can be readily prepared with high radiochemical purity to provide a dose of 3 mCi (111 GBq)/100,000 particles, which provides images of high

^ MacDonald A, Burrell S (September 2008). Tc-99m MAA SPECT has a predictive value in terms of response to radioembolization, PFS, and OS. Dosimetry based on Tc-99m MAA SPECT images can be used in the selection of patients and, Technetium Tc 99m Albumin Aggregated Injection. It is also not known whether Technetium Tc 99m Albumin Aggregated Injection can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. There have been no studies in pregnant women. Technetium Tc 99m Albumin Aggregated Injection Tc MAA) - primarily used for lung scanning; 90-95% of administered dose (3mCi/injected) is trapped in the capillary bed of the lungs within a few seconds after intravenous administration.

This is an imaging technology that enables a patient-specific plan before the treatment and is performed during diagnostic angiography.

Tc]-MAA may be induced by different drugs. 11 Aug 2011 Abstract Tc-99m macroaggregated albumin (MAA) hepatic perfusion study and hepatic angiography are routinely performed prior to yttrium-90 Background: To retrospectively analyze perilesional technetium Tc-99m MAA injection for intraoperative localization of atypical soft-tissue and bone lesions 1 Dec 2020 Technetium Tc 99m Albumin Aggregated Injection is a radioactive diagnostic agent indicated for: Lung scintigraphy as an adjunct in the 5 Feb 2021 Tc-MAA SPECT/CT is more appropriate in showing the functional status of a tumor, because it can show the masses of viable tumor, necrotic 15 Oct 2018 Abstract. Extra-pulmonary accumulation of Tc-99m-macroaggregated albumin ( MAA) is described as uptake areas out of the lung in perfusion. 26 Jan 1996 The thyroid uptake following the administration of Tc-99m macroaggregated albumin (MAA) was an unexpected finding. Investigating the Y-90 Sirsphere (SirTex) is similar in term of lung shunt estimate. Tc-99m MAA imaging is utilized to assess pulmonary shunting which will affect treatment dose.

Initial U.S. Approval: 1976 Technetium Tc 99m Albumin Aggregated Injection is a radioactive diagnostic agent indicated for: Pulmonary scan as a complement to pulmonary infusion evaluation in adults and kit for preparation of technetium Tc 99m albumin aggregated injection Each multiple-dose vial contains 2 mg of albumin aggregated as lyophilized powder Each 5-vial kit contains 5 multiple-dose Tc MAA) - primarily used for lung scanning; 90-95% of administered dose (3mCi/injected) is trapped in the capillary bed of the lungs within a few seconds after intravenous administration.

Tc-99m MAA (macroaggregated albumin) is one of the technetium radiopharmaceuticals used in lung perfusion imaging. Characteristics photon energy: 140 KeV physical half life: 6 hours biological half life: 2-3 hours normal distribution: lungs, 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. This safety record is attributable to the very small fraction of the pulmonary vasculature that is occluded by the typical injection of Tc-MAA. That number is typically quoted to be < 0.1%, or MAA kits were prepared with a more reasonable amount of Tc-99m and yielded high radiochemical purity values in typical incubation times.
