Biodistribution and dosimetry of free118Te, anin vivogenerator of the positron emitter118Sb for long-term positron emission tomography.
Objective. Tellurium-118 (118Te;t1/2= 6.00 ± 0.02 d) can act as anin vivogenerator of the positron emitter antimony-118 (118Sb;t1/2= 3.6 ± 0.3 min), enabling positron emission tomography (PET) over a week or longer. This work assessed absorbed doses associated with free118Te to establish a dosimetric safety basis for11...
