13C-fructose
has been recently proposed as a novel hyperpolarized 13C probe.
The short T1 of 13C-fructose could impose additional
challenges in designing data acquisition strategies. Here, we have optimized
an acquisition scheme using a specialized simulation tool and showed that a T1
compensated RF excitation scheme together with compressed sensing can yield
minimized spatial blurring with high SNR enough for in vivo 13C-fructose metabolic imaging.
