Activity depends on the body surface area (BSA) and the extent of tumor liver involvement. BSA in square meters was calculated using standard nomograms. Tumor liver involvement was measured on CT or MRI. The activity was then calculated using the formula Activity (GBq) = (BSA - 0,2) + (tumor volume/total liver volume). The calculated activity was reduced for patients with lung shunt from 10% to 20% and treatment was contraindicated if the lung shunt was higher than 20%. For those patients receiving lobar therapy, the activity could be reduced proportionally to the relative volume of the treated lobe compared to whole liver volume. [Pg.109]
