Comparison of Imaging Characteristics of uEXPLORER and Conventional PET/CT in Patients With Lung Cancer, Lymphoma, and Melanoma

Study summary

To determine the minimum scan duration for fluorine-18 positron-emitting radioactive isotope-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/computed tomography (CT) scans performed on a total-body PET/CT scanner that results in non-inferior image quality to 18F-FDG PET/CT scans performed on a conventional PET/CT scanner. The subject population will be patients being staged for lung cancer, lymphoma, or melanoma.
