The application of radiopharmaceuticals in medico imaging along with PET and CT has increased surprisingly. This article is about a specific use of 18 F labeled fluoro-2-deoxyglucose ( 18 F-FDG) in combination with PET/CT for the oral and maxillofacial imaging. This will aid the learning of oral and maxillofacial radiology. PET is a functional imaging technique.
In this technique, an isotope or radiolabeled carrier molecule is injected into patient intravenously which gets distributed in different tissues and emits positrons or positively charged electron. The external detectors in PET positioned at different orientation detect the radiations or positrons emitted by radiopharmaceuticals. The most common positron emitting radiopharmaceuticals are 11 C, 13 N, 15 O, 18 F, and 68 Ga. However, most of the clinical applications associated with PET/CT have engaged 18 F-labeled…
