Simultaneous magnetic resonance angiography and perfusion with nuclear magnetic resonance fingerprinting
Embodiments associated with combined magnetic resonance angiography and perfusion (MRAP) and nuclear magnetic resonance (NMR) fingerprinting are described. One example apparatus repetitively and variably samples a (k, t, E) space associated with an object to acquire a set of NMR signals that are associated with different points in the (k, t, E) space. Sampling is performed with t and/or E varying in a non-constant way. The apparatus includes a signal logic that produces an NMR signal evolution from the NMR signals and a characterization logic that characterizes a resonant species in the object as a result of comparing acquired signals to reference signals. The apparatus includes an MRAP logic that simultaneously performs MR angiography and produces quantitative perfusion maps. A multi-factor MR bio-imaging panel is produced from a combination of the data provided by the MRAP and NMR fingerprinting. Diagnoses may be made from the multi-factor MR bio-imaging panel.
