Magnetic Resonance Spectroscopic Imaging with Short Echo Times

摘要

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.
