Classification: CPC G | IPC G

Claim 9:
10. A magnetic resonance imaging (MRI) system comprising:
a magnet system configured to generate a static magnetic field (B0) about at least a portion of a subject arranged in the MRI system;
a plurality of gradient coils configured to apply magnetic gradients to the static magnetic field;
a radio frequency (RF) system configured to apply an excitation field to the subject and acquire MR image data from the subject;
a computer system programmed to:
control the plurality of gradient coils and the RF system to perform a gradient echo pulse sequence that includes a phase increment of an RF pulse of the gradient echo pulse sequence selected to encode diffusion information into a phase of MR signals;
control the plurality of gradient coils and the RF system to acquire the MR signals as MR data;
process the MR data to determine MR signals corresponding to diffusion in the subject when acquiring the MR signals; and
generate at least one of an image or a map of the subject indicating the diffusion in the subject from the MR data; and

wherein the MR data corresponding to a first of the multiple repetitions includes a fast imaging with steady-state precession (FISP) echo (S1+) and a second of the multiple repetitions includes a time reversed fast imaging with steady state precession (PSIF) echo (S1−).
