Positron ranges obtained from biomedically important positron-emitting radionuclides.

Abstract

Positron ranges were obtained experimentally for several nuclides used in scintigraphic imaging. The nuclides examined were 13C, 13N, 15O, 18F, 68Ga, and 82Rb. The results are discussed with respect to the ultimate spatial resolution obrained in a scintigraphic image.
