Magnetic resonance imaging with high spatial and temporal resolution

摘要

Methods, systems, and apparatus for magnetic resonance imaging (MRI) are described. In one example, the method includes applying a sample-selective magnetic field gradient sequence along a slice direction to partition responses from a sample under magnetic resonance imaging into a plurality of different regions of slices in the k space, applying spiral readout gradients to the sample to obtain echo data from the sample, and applying a Time Resolved Imaging of Contrast Kinetics imaging technique to sample the different regions of slices in the k space.

1. A method for magnetic resonance imaging (MRI) of a sample, comprising:
obtaining sample information in a spiral readout trajectory in-plane in a k-space from a section of the sample; employing volume encoding along a slice direction in the k-space, wherein the slice direction is orthogonal to the in-plane; partitioning the encoded section into a plurality of regions in the k-space, the plurality of regions including a central region at the k-space center; acquiring sample information from the plurality of regions, wherein the sample information from the central region is acquired more often than the sample information from regions away from the k-space center; and causing the magnetic resonance imaging (MRI) of the sample acquired from the plurality of regions to be displayed on a display device.
