A rapidly emerging clinical application of positron emission tomography (PET) is the detection of cancer with radionuchde tracer, because it provides information unavailable by ultrasound, computed tomography or magnetic resonance imaging The most commonly used radiotracer for PET oncologic imaging is fluorme-18-labeled fluorodeoxyglucose (^<18>F-FDG) Early studies show PET has potential value in viewing the region of the tumor, detecting, staging, grading, monitoring response to anticancer therapy, and differentiating recurrent or residual disease from post treatment changes. However, limitations of FDG-PET in the head and neck region, namely, physiological FDG uptake in the salivary glands and palatine tonsils, have been reported, increasing the false-positive rates in image interpretation. This review was designed to address these distinctions of oral cancer PET imaging (1) Specialization of PET equipment, (2) Cancer cell metabolism, proliferation and tracers, (3) Clinical diagnosis of oral cancer with PET, (4) Pitfalls in oncologic diagnosis with FDG-PET imaging.
