Dose calculations for [¹³¹I] meta-iodobenzylguanidine-induced bystander effects

, 2014
Targeted radiotherapy is a potentially useful treatment for some cancers and may be potentiated by bystander effects. However, without estimation of absorbed dose, it is difficult to compare the effects with conventional external radiation treatment ...
