Radio frequency (rf) pulses are applied to a sample to produce magnetic
resonance (MR) echo signals from the sample at multiple different echo
times. Magnetic field gradients are applied to the sample to select for
acquisition components of each MR echo signal. The selected components
correspond to groups of radial projections in k-space. Each group is
associated with one of the echo times. Each group defines a different set
of projection angles in the k-space, and the groups are interleaved to
reduce streak artifacts in spectroscopic images associated with a
resonance frequency. Images of the sample are generated based on acquired
MR signals. In some implementations, an echo time of eight microseconds
or less is included in the multiple different echo times.
