Table 1 99mTc-MAA and 90Y-microspheres injection sites, percentage of 99mTc-MAA activity administered through every artery (decided by IR based on liver and tumor volumes) and split of 90Y-microspheres prescribed by each artery (in up to 42% of patients according to CBCT volumetric information)

From: The joint use of 99mTc-MAA-SPECT/CT and cone-beam CT optimizes radioembolization planning
