Case ReportsMetastatic colon cancer to the lung with no detectable primary tumor, mimicking advanced primary lung cancer on F-18 FDG PET/CT imaging.
An 83-year-old man was referred with a right lung mass on dynamic chest computed tomography (CT). F-18 fluoro-deoxy-glucose positron emission tomography (FDG PET)/CT showed intense FDG uptake in the right lung mass and bilateral hypermetabolic mediastinal lymph nodes. CT-guided biopsy of the right lung mass revealed metastatic adenocarcinoma from the colon, but a colon cancer lesion was not detected by dynamic abdominal CT and colonoscopy.

Comparative StudyComparative evaluation of F-18 FDOPA, F-18 FDG, and F-18 FLT-PET/CT for metabolic imaging of low grade gliomas.
We undertook this prospective study to compare amino acid metabolism, glucose metabolism, and proliferation in primary and recurrent low grade gliomas using positron emission tomography (PET)/computed tomography with F-18 FDOPA, F-18 FDG, and F-18 FLT. ⋯ F-18 FDOPA scan is superior to both F-18 FLT and F-18 FDG for visualization of primary and recurrent low grade gliomas. F-18-FLT should not be considered for evaluation of recurrent low grade gliomas.

Review Clinical TrialFDG PET-CT in the management of primary breast lymphoma.
Primary breast lymphoma (PBL) is a rare disease and its management differs from other breast cancers. The purpose of this study is to evaluate the role of FDG PET-CT in the management of PBL. We carried out 16 PET-CT scans and reviewed the literature. ⋯ FDG PET-CT has a definitive role in every step of management (diagnosis, staging, treatment response evaluation, and detection of recurrence) in patients with primary breast lymphoma.
