iodine I 124 iobenguane
A radioconjugate composed of the positron-emitting radioisotope iodine I 124 labeled to iobenguane, the synthetic aralkylguanidine analogue of the neurotransmitter norepinephrine (NE), with potential diagnostic imaging applications upon positron emitting tomography (PET) or computed tomography (CT). Upon administration, iodine I 124 iobenguane is taken up and accumulates in the granules of adrenal medullary chromaffin cells and in the pre-synaptic granules of adrenergic neurons in a manner almost identical with that of NE. In turn, tumor cells can be imaged upon PET or CT. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
