From: The Impact of Ageing on 11C-Hydroxyephedrine Uptake in the Rat Heart

Uptake of radioactivity in the rat heart of 4 different animals (at an age of 2 months) after injection of 11C-HED with different specific activities. (A) Representative axial PET images 25–30 min post-injection of 11C-HED. (B) Time-activity curves for the myocardium with different amount of cold doses. A dose-dependent reduction of cardiac 11C-HED uptake can be observed.
