A fast computed tomographic imaging method for myocardial perfusion.
Fast x-ray computed tomography can be used to generate indicator dilution curves in perfused tissues following intravascular injection of roentgen contrast agent. These curves can be used to estimate regional parenchymal perfusion, intravascular blood volume, heterogeneity of these two parameters, and vascular bed transfer function.
