What is the average recommended number of MAA particles to be administered?

The average recommended number of macroaggregated albumin (MAA) particles to be administered typically falls within the range of 350,000 particles. This dosing is crucial in certain diagnostic and therapeutic procedures, particularly in lung perfusion imaging and radioembolization.

The rationale for administering approximately 350,000 particles is rooted in ensuring adequate visualization and targeting during imaging studies or treatments. An optimal number allows for sufficient coverage of the targeted vascular regions while minimizing the risk of unwanted embolization elsewhere. The specific quantity is tailored to achieve the best balance between effective assessment of pulmonary blood flow and safety for the patient.

Other dosing options may not align with the standard protocols or the particulars of the procedural guidelines established in clinical practice, which prioritize accuracy and safety in the administration of radiotracers.
