Recently, a considerable amount of research has focused on the use of positron emission tomography (PET) using fluorine-18-labeled (18F) fluoro-2-deoxy-D-glucose (FDG) as an important oncologic imaging tool in the oral and maxillofacial region. PET using 18F-FDG is especially useful to differentiate benign or malignant primary tumors in oral cancer. However, the normal anatomy of the oral and maxillofacial region is very complex, and substantial variations in uptake are observed in and around the oral cavity. Therefore, there were some cases of oral cancer which were difficult for radiologists to diagnose precisely. In this review, we discuss why normal tissues, dental-related metal artifacts, and dental infections are considered to be the important pitfalls in the diagnosis of primary oral cancers using 18F-FDG-PET-CT.
