title: Potassium Chloride Infusion as the Cause of Altered Bio Distribution of18F-Fluorodeoxyglucose on Whole-Body Positron Emission Tomography-Computed Tomography Scan.
abstract: 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography-computed tomography is a standard diagnostic imaging tool in many types of cancer. Its physiologicalin vivodistribution includes the brain, liver, heart, kidneys, and urinary tract at 1 h after tracer injection. Skeletal muscle is known to show variable amounts of18F-FDG uptake because it has a relatively high-glucose metabolism. We report a case of a 20-year-old patient with gross18F-FDG uptake involving multiple muscle groups and its likely correlation to potassium chloride infusion before18F-FDG injection.
