Parallel imaging can aid hyperpolarized 13C MRI in extracting more information in the limited time window of the hyperpolarized signal. Using a dedicated, flexible 13C receive coil design with coupling coefficients matched for both 13C and 23Na, sensitivity profiles for reconstruction can be acquired at the 23Na frequency. We demonstrate this method in two hyperpolarized in vivo experiments involving pig kidneys and human brain using a two-times accelerated 3D blipped stack-of-spirals sequence with dual-resolution. The results show good SNR, coverage, and resolution. The method is promising for
integrating and automating parallel imaging for hyperpolarized 13C MRI.
