Spiral Multiband Pulse Sequence Developed Resolved Hyperpolarized [1,4-¹³C₂]Fumarate Perfusing the Heart in Both Control and Infarcted Animals, 1 Day After Infarction

[1,4-¹³C₂]malate production was only visible in infarcted animals, and was localized to the anterior region of the chest wall, consistent with the location of the insult. The color axis is linear for the 4 hyperpolarized datasets, with the maximum level scaled down by the factor shown. Proton underlay images have been subject to a gamma correction ($\gamma =\frac{1}{2}$) to improve visualization of the cardiac structures.
