(Focused Ion Beam-Scanning Electron Microscope, NCI Thesaurus)
A nuclear imaging procedure in which gallium-67 is used as the radiopharmaceutical.
(Gallium scan, NCI Thesaurus)
The gallium is taken up by rapidly dividing cells in the bones, tissues, and organs and is detected by a scanner.
(Gallium scan, NCI Dictionary)
Although the mechanism is unknown, gallium Ga 67 concentrates in lysosomes and is bound to a soluble intracellular protein in certain viable primary and metastatic tumors and focal sites of inflammation, allowing scintigraphic localization.
