Tumor imaging with positron emission tomography (PET) may improve the diagnosis and subsequent treatment of lung cancer patients, according to a review published online November 27 in the Journal of the National Cancer Institute.Tumor imaging is frequently used in the diagnosis of lung cancer and is important for making treatment decisions. Standard imaging technologies, such as magnetic resonance imaging or computed tomography imaging, provide information on anatomical changes, but PET imaging is based on biochemical processes that may detect disease even before anatomical changes occur. Therefore, PET imaging may complement standard imaging in the diagnosis of lung cancer.
