Figure 5From: Preclinical evaluation of carbon-11 and fluorine-18 sulfonamide derivatives for in vivo radiolabeling of erythrocytes Time activity curves of [18 F]-(5) in various organs versus myocardial blood pool activity. Time activity curves of [18F]-(5) in the liver, spleen, and kidneys of a Wistar rat in comparison with the myocardial blood pool activity illustrating good retention of tracer in the blood pool compartment with excellent target-to-background ratios.Back to article page
