Myocardial (myo) and blood pool (blood) T1 relaxation times before contrast application (native), after the first perfusion (half dose, 0.05 mmol/kg), and after the second perfusion (full dose, total of 0.1 mmol/kg). dT time between the perfusion scan and the T1 mapping scan, ECV extracellular volume, HR heart rate. Continuous values as mean ± standard deviation, nominal values as number and percentage. T1 mapping and ECV mean of both readers.
