چکیده

The fusion of 18-fluorodeoxyglucose (FDG) positron-emission tomography (PET) with computed tomography (CT) offers both anatomic and physiologic delineation of head and neck cancers. PET-CT is useful in the staging of head and neck carcinomas and may identify unsuspected distant metastasis that may alter treatment. PET-CT may also help in target volume delineation during radiotherapy (RT) treatment planning. Better characterization of the target may improve local control as well as spare normal tissues from RT sequelae.

Value of Dedicated Head and Neck 18F-FDG PET/CT Protocol in Detecting Recurrent and Metastatic Lesions in Post-surgical Differentiated Thyroid Carcinoma Patients with High Serum Thyroglobulin Level and Negative 131I Whole-body Scan

Objective(s): In clinical practice, approximately 10-25% of post-surgical differentiated thyroid carcinoma (DTC) patients with high serum thyroglobulin (Tg) and negative 131I whole-body scan (WBS) have poor prognosis due to recurrent or metastatic lesions after radioactive iodine treatment. The purpose of this study was to evaluate the value of 18F-FDG PET/CT scan in DTC patients with high seru...

Clinical Applications of FDG PET and PET/CT in Head and Neck Cancer

18F-FDG PET plays an increasing role in diagnosis and management planning of head and neck cancer. Hybrid PET/CT has promoted the field of molecular imaging in head and neck cancer. This modality is particular relevant in the head and neck region, given the complex anatomy and variable physiologic FDG uptake patterns. The vast majority of 18F-FDG PET and PET/CT applications in head and neck can...
