Abstract
It is often difficult to compound a dose of technetium-99m (99mTc) macroaggregated albumin, which contains both a specified number of particles, as well as a specific dose in millicuries. This is further complicated by the fact that the commercial kit used contains many times more particles than is needed, particularly in the pediatric patient population. We have developed a set of simple formulas to facilitate calculating the number of millicuries and volume of sodium pertechnetate (99mTc) to be added to the kit.
