Physiologic oropharyngeal uptake is seen

Webb27 sep. 2024 · Oropharyngeal FDG uptake was asymmetrical in 57.3% of the cases. Uptake was more common in the tonsils (56.3%), followed by the tongue base (31.1%) and both sites (12.6%). In 41.7% of reports, appearance was described as likely physiological; however, 52.4% of reports advised direct visualisation, clinical correlation or ENT opinion. WebbPhysiologic uptake of FDG is frequently seen in the abdomen and can be related to variable bowel uptake or focal stasis of excreted radiotracer in the ureters [6–9]. Pathologic uptake of FDG in the intestine can present in a pattern that is focal (e.g., tumor or polyp), segmental (e.g., Crohn's disease or normal variant), or diffuse (e.g., colitis).
