PULMOTECH MAA (technetium tc99m albumin aggregated)
Pulmotech MAA is a radioactive diagnostic agent used in medical imaging procedures for both adult and pediatric patients. After radiolabeling with technetium-99m, the agent is utilized as an adjunct in lung scintigraphy to evaluate pulmonary perfusion. In adult populations, it is also indicated for use in peritoneovenous shunt scintigraphy to assist in the assessment of shunt patency.
How PULMOTECH MAA Works
Following intravenous injection, more than 90 percent of the technetium Tc 99m albumin aggregated particles are trapped within the arterioles and capillaries of the lungs. For shunt evaluation, the agent is administered intraperitoneally where it mixes with peritoneal fluid. The rate at which the agent clears from the peritoneal cavity and enters systemic circulation indicates whether the peritoneovenous shunt is patent or blocked.
