Abstract
Methods and systems perform magnetic resonance fingerprinting (MRF) by obtaining scan data of a sample at a low-resolution over a k-space and obtaining other scan data at a high-resolution over the k-space. This scan data may be captured over the same regions, different regions, or where one scan data is captured over a sub-region of the other. The low-resolution and high-resolution scanning is repeated according to a scanning ratio between the first scan data and the second scan data to generate interleaved low-resolution and high-resolution scan data. From that interleaved low-resolution and high-resolution scan data, high-resolution tissue property maps of the sample are generated.
