Gallium-68

特許 係属中 The shorter-lived gallium-68 (half-life 68 minutes) is a positron-emitting isotope which is generated from germanium-68 in gallium-68 generators, for use in a small minority of diagnostic PET scans. For this use, it is usually attached as a tracer to a carrier molecule, which gives the resulting radiopharmaceutical a different tissue-uptake specificity from the ionic Ga-67 radioisotope normally used in standard gallium scans.
