Fast dynamic 3D MR spectroscopic imaging with compressed sensing and multiband excitation pulses for hyperpolarized.

The article offers information on a cellular metabolism study that is conducted to develop a three-dimensional magnetic resonance spectroscopic imaging method to acquire hyperpolarized data, that combines excitation pulses which are effective in magnetization. It discusses the achievement of a two-second temporal resolution with a hyperpolarized pyruvate. It describes the creation of a random undersampling pattern and the customization of the excitation pulses.
