NCIt related terms : 18F-EF5;
NCIt definition : A radioconjugate consisting of EF5, a fluorinated derivative of etanidazole, conjugated
to fluorine F 18, a positron emitting isotope. EF5 binds to hypoxic tissue; conjugation
to Fluorine F 18 allows imaging of hypoxic regions within tumors. (NCI05);
Alternative definition : NCI-GLOSS: A substance being studied in positron emission tomography (PET) imaging
to detect tumor hypoxia (a low level of oxygen in the tumor). This may help predict
how the tumor will respond to treatment. It is a type of radiopharmaceutical.;
