摘要： Systems and methods for performing diffusion-weighted magnetic resonance imaging ("MRI"), including reconstructing and analyzing images, while preserving phase information that is traditionally discarded in such applications, are provided. For instance, background phase variations are eliminated, which enables complex-valued data analysis without the usual noise bias. As a result, the systems and methods described here provide an image reconstruction that enables true signal averaging, which increases signal-to-noise ratio ("SNR") and allows higher contrast in diffusion model reconstructions without a magnitude bias.

摘要： A system and method of obtaining diffusion weighted images uses a magnetic-resonance imaging system and includes, for at least a first slice, exciting spins of the slice, then: applying a diffusion weighting gradient in i'th direction of N diffusion- weighted directions; sweeping a readout gradient across an EPI short-axis blade oriented at a first angle, pulsing phase-encoding gradient, recording spin-echo signal magnitudes in k-space memory for the short-axis blade; and simultaneously rotating the diffusion gradient direction to a next direction of the N directions and rotating the short axis blade to another angle. Storing spin-echo signals in k-space memory is repeated for a rotated short-axis blade with the rotated diffusion gradient. Composite reconstruction is done by "training" the i th low-resolution image from Fourier transform of i th k-space blade with the i th high-resolution composite image from Fourier transform of collected k-space EPI blades of neighborhood diffusion directions.

摘要： A magnetic resonance imaging (MRI) system (500), the system includes at least one controller (510) which performs a modified rotated slab excitation (mROSE) sequence for volume selection to exclude portions of a subject under exam which are within the scanning volume and outside of a field-of-view (FOV) so as to reduce foldover artifacts which originate from the excluded portions of the subject under exam, where the mROSE sequence performs volume excitation based upon either optimized symmetrical, minimum-phase, or stretched minimum-phase radio- frequency (RF) pulses in a sagittal plane and encodes the scanning volume in a coronal plane. The controller also performs a chemical-shift sequence including a modified DIXON (mDIXON) sequence for substantially uniform fat/water separation within a FOV which lies within the scanning volume; and/or acquires echo information for reconstructing at least a part of an image.
