Regadenoson Timing Protocols (A–E) Each row represents a different timing sequence, depicting time along the x-axis for 3 different components: regadenoson administration (top line), Rb-82 generator activation and radiotracer infusion (teal dot along middle line), and positron emission tomography (PET) imaging (bottom line). Thick black lines denote activity on the thin gray timelines. The regadenoson bolus lasted 10 s for all protocols, followed by a 5-ml saline flush. Typically, 10 to 15 s elapsed between generator activation and radiotracer injection, here denoted as a fixed 15-s interval. PET imaging began coincident with radiotracer infusion and occurred in 2 sequential components: a 2-min arterial phase followed immediately by a 5-min myocardial phase. The pink arrow and text for each sequence gives the time between starting the regadenoson bolus and activating the generator.
