Abstract
Example apparatus and methods are provided to reconstruct under-sampled three-dimensional (3D) data associated with nuclear magnetic resonance (NMR) signals acquired from a liver. The data is reconstructed using a 3D through-time non-Cartesian generalized auto-calibrating partially parallel acquisitions (GRAPPA) approach to produce a quantized value for a contrast agent concentration in the liver from a signal intensity in the data based, at least in part, on a compartment model of the liver. The quantized value describes a perfusion parameter for the liver.
