Reply: 99mTc-MAA–Based Dosimetry for Liver Cancer Treated Using 90Y-Loaded Microspheres: Known Proof of Effectiveness

REPLY: We thank Dr. Garin et al. for their expert insights into the complex topic of radioembolization dosimetry. For 90Y hepatic radioembolization, 99mTc-macroaggregated albumin (99mTc-MAA) administered as an intraarterial simulation imaging agent is primarily used for calculation of the lung shunt
