A previous hyperpolarized 1 H imaging experiment utilized in-phase magnetization generated from the PASADENA signal under J-coupling evolution during the echo time of the imaging scheme. In Singlet-Contrast MRI, the hyperpolarization is stored in a long-lived singlet state before imaging, and the method additionally overcomes some of the limitations of that approach; it is more general, as it can be combined with any imaging scheme without synchronizing the delays to the couplings of the hyperpolarized molecule. This allows one to easily acquire images of the hyperpolarized signal at different points in time, which makes real-time tracing of metabolic processes possible. Additionally, it does not require that the background and hyperpolarized 1 H signals have different relaxation properties for background suppression .
