11C-Acetate Positron Emission Tomography Imaging for Lung Adenocarcinoma 1 to 3 cm in Size With Ground-Glass Opacity Images on Computed Tomography

AC-PET detected approximately one third of well-differentiated adenocarcinomas of the lung which were not identified by FDG-PET. AC-PET could be useful to diagnose pulmonary nodules with ground-glass opacity images which were not identified by FDG-PET.
