Question

An MAA kit has 3,000,000 total particles, if a 5 mCi dose is needed at 1000 and the following information is provided

25 mCi/mL in 5 mL total volume at 0700
what approximate number of particles will be given to the patient?
a. 600,000
b. 120,000
c. 169,635
d. 134, 831

Answer 1

The patient would receive approximately 3000 particles. This is through calculating the ratio of dose to particles and multiplying it with the dose needed. The MAA kit is used in nuclear medicine dosing.

Step-by-step explanation:

To calculate the number of particles, we first need to find the ratio of dose to particles of the MAA kit. After which, we identify the required dose for the patient. The MAA kit has 3,000,000 particles and it is given in a 5 mCi dose, so the ratio is 600,000 particles/mCi. The 5 mCi dose required actually refers to 5 mCi per 1000 mL, so the actual dose needed is 0.005 mCi. Therefore, the dose to particles ratio is multiplied by this dose needed:

600,000 particles/mCi x 0.005 mCi = 3000 particles.

So none of the provided choices are correct. The patient would actually receive approximately 3000 particles. This method is based on the principles of nuclear medicine dosing, specifically regarding the use of Macroaggregated Albumin (MAA) kits in diagnostic procedures.
