Core Tip

Core tip: The 18-fluorodeoxygluocose positron emission tomography (18FDG-PET) scan has increasing clinical importance in the management of head and neck cancers. It has also proven useful in treatment planning for radiation therapy. PET scans have utility in tumor volume delineation, the identification of metastatic lymph nodes, the management of carcinoma of unknown primary, dental artifact reduction and high-risk postoperative radiation therapy. Many of these applications of 18FDG-PET scans are still in the preliminary stages of development and active investigations are ongoing to standardize these processes.
