Abstract: Systems and methods capable of improving acquisition times associated with obtaining diffusion-weighted magnetic resonance imaging data are discussed. In aspects, multiple points in q-space can be sampled in a single repetition time (TR). Acquisition time can be further increased using other techniques, such as a radial raster or compressed sensing.

Abstract: A method for producing a magnetic resonance image using an ultra-short echo time. The method includes applying a pulse sequence to an object, detecting a spirally encoded and phase encoded magnetic resonance signal associated with the object, and reconstructing the magnetic resonance image based on the spirally encoded and phase encoded magnetic resonance signal. The pulse sequence includes a slab-selective radiofrequency pulse, a slab-selective gradient pulse, a plurality of variable duration slice encoding gradient pulses, a plurality of first spiral encoding gradient pulses, and a plurality of second spiral encoding gradient pulses. The detection of the spirally encoded and phase encoded magnetic resonance signal occurs concurrently with the application of one of the plurality of first spiral encoding gradient pulses and with the application of one of the plurality of second spiral encoding gradient pulses.
