History of Radioiodine
 1937-
John Livingood and Glenn
Seaborg discovered iodine-131 and
cobalt-60.
 1946- Seidlin, Marinelli and Oshry
treated a patient with thyroid cancer
with iodine-131, an “atomic cocktail.”
 1950- Human serum albumin (RISA)
labeled with iodine-131 for imaging the
blood pool within the heart.

Other Significant Dates
 1958-
Hal Anger invented the
“scintillation camera.”
 1960- BNL advertises Tc-99m
generators.
 1962- David Kuhl introduced emission
reconstruction tomography – ultimately
became SPECT and PET and CT.
 1971- AMA officially recognized nuclear
medicine as a medical specialty.
