Drinking Large Volume of Hot Water May Cause Increased 18 F-FDG Uptake in Esophagus

Clin Nucl Med. 2024 Jun 1;49(6):576-577. doi: 10.1097/RLU.0000000000005170. Epub 2024 Mar 18.

Abstract

We present 2 cases of diffuse FDG accumulation in the esophagus due to drinking hot water before an 18 F-FDG PET/CT scan. Drinking large volume of hot water immediately before the FDG PET/CT study may lead to challenges in the interpretation of the hypermetabolic esophagus.
