Magnetic resonance fingerprinting with steady state precession (MRF-FISP)

Example embodiments associated with NMR fingerprinting are described. One example NMR apparatus includes an NMR logic that 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. Sampling is performed in response to a fast imaging with steady state free precession (MRF-FISP) pulse sequence having an unbalanced gradient that dephases transverse magnetization. The NMR apparatus may also include 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 unbalanced gradient in the MRF-FISP pulse sequence reduces sensitivity to B0 in homogeneity.

Arterial spin labeling (ASL) with magnetic resonance fingerprinting (MRF)

Example apparatus and methods perform magnetic resonance fingerprinting (MRF) for arterial spin labeling (ASL) based parameter quantification. ASL with MRF produces a nuclear magnetic resonance signal time course from which simultaneous quantification of ASL perfusion-related parameters can be achieved. The parameters may include cerebral blood flow, transit time, T1, or other parameters. The quantification uses values from a dictionary of signal time courses that were generated or augmented using Bloch simulation, knowledge of the sequence, or previous observations. The dictionary may account for inflow or outflow of labeled spins and may model arterial input. An ASL-MRF pulse sequence may differ from conventional pulse sequences. For example, an ASL-MRF pulse sequence may include non-uniform control pulses, non-uniform label pulses, non-uniform post labeling delay time, non-uniform background suppression pulses, non-uniform acquisition repetition time, or non-uniform acquisition flip angle.
