Patent ID: 7602184

Claim:
A method of magnetic resonance imaging comprising: applying to a sample at least one radio frequency (rf) pulse configured to produce a plurality of magnetic resonance echo signals from the sample, each echo signal corresponding to one of a plurality of echo times; applying to the sample magnetic field gradients configured to select for acquisition components of each of the magnetic resonance echo signals, the selected components corresponding to a plurality of groups of radial projections in a two-dimensional spatial frequency domain of the sample, each group associated with one of the plurality of echo times and defining a different plurality of projection angles in the spatial frequency domain, the groups interleaved to reduce streak artifacts in spectroscopic images associated with a resonance frequency; acquiring the selected magnetic resonance signals; and generating a plurality of images of the sample based on the acquired magnetic resonance signals, each image associated with one of the plurality of echo times, the image associated with a given echo time based at least in part on low spatial frequency components of the group of radial projections associated with the given echo time and high spatial frequency components of at least one other group of radial projections.
