Hyperpolarized 13C magnetic resonance imaging is a non-invasive imaging tool to assess metabolic process in-vivo that has been most commonly applied to imaging cancer and heart disease. Spiral readout, as a rapid acquisition technique, is commonly used to acquire hyperpolarized metabolic data. However, the spiral readout is sensitive to the off-resonance effect and has blurring artifacts as a result. The blurring also affects the measurement of metabolism. In this project, we investigated two off-resonance correction methods with self-estimated field maps and applied them on different anatomies.
