Fig. 2From: The relative contributions of myocardial perfusion, blood volume and extracellular volume to native T1 and native T2 at rest and during adenosine stress in normal physiologyThe effect of adenosine stress on native T1, native T2, myocardial perfusion, MBV and ECV. All mean values of the respective parameters increased with adenosine stress. Three healthy subjects decreased in ECV during adenosine stress, which is likely due to low measurement precision affected by heart rate at stressBack to article page
