Abstract

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.
