Advances of research on PET-CT hypoxia imaging in lung cancer

PET-CT, as a single imaging modality for whole body providing both anatomic and biological information, offer, the possibility of in vivo mapping of regional tumor hypoxia with adequate anatomical resolution as well as monitoring therapy through follow-up mapping of hypoxia. Some new advances of research and clinical study on PET-CT hypoxia imaging in lung cancer were summarized briefly, including tracers, the detections of hypoxia, therapy planning, predictions and outcome.
