Metabolic imaging with hyperpolarized 13C substrates often detects signals only from small subregions within the prescribed FOV, primarily due to lacking background signals and limited perfusion or metabolic activities in the adjacent tissues. In this study, we propose an imaging method that provides flexible reconstruction options with variable FOV. The proposed pulse sequence was implemented, and the feasibility of the reconstruction method was validated with a 13C phantom.
