Abstract

Systems and methods to determine a first map of a first parameter based on first signals acquired by a magnetic resonance imaging system, the first map associating each of a plurality of voxels with a respective value of the first parameter, the first parameter quantifying a first physical characteristic of an object represented by the plurality of voxels, determine a second map of a second parameter based on the first signals, the second map associating each of the plurality of voxels with a respective value of the second parameter, the second parameter quantifying a second physical characteristic of the object, and determine a dark-blood phase-sensitive inversion recovery late gadolinium enhancement image based on the first map of the first parameter and on the second map of the second parameter.
