A technique is presented for the absolute quantification of myocardial perfusion in a 3D volume covering the whole ventricle using contrast-enhanced myocardial first-pass perfusion imaging. After the contrast agent injection, a highly accelerated 3D volume is acquired for each consecutive heartbeat using a saturation-recovery prepared FLASH sequence with a stack-of-spirals trajectory. After the acquisition, missing data are reconstructed by applying parallel imaging in all spatial dimensions. By applying a dual-bolus approach, an unsaturated arterial input function is determined, and absolute perfusion values are quantified in the entire myocardium.
