Positron emission tomography(PET) is a diagnostic method that creates high
resolution, 3-Dimentional tomographic images of the distribution of positron emitting
radionuclides in human body. Computed tomography(CT) and magnetic resonance
imaging(MRI) are routinely used to delineate the presence and extent of primary and
metastatic oral and maxillofacial malignancy. Because the CT and MRI criteria for
malignancy depend upon morphology, these imaging techniques have limitations in their
ability to identify malignant tissue when fascial planes are distorted or destroyed. PET
has the advantage of imaging metabolic changes that appear to be linked to malignancy.
Recently, PET has shown promise in the early detection of primary and metastatic oral
and maxillofacial canter and has been used to evaluate the tumor response to
chemotherapy and radiotherapy. We report cases of diagnosis of oral and maxillofacial
cancers and review the literatures to determine whether PET is effective in identifying
oral and maxillofacial tumors.
