Abstract
The presently disclosed subject matter demonstrates that a spin state which has zero magnetic resonance signal, but an extremely long lifetime, can be used to store magnetization, which can then be recovered into an observable transition. Coupled with hyperpolarization techniques, this permits the preparation of a wide range of contrast agent molecules for use in magnetic resonance imaging (MRI) techniques that have long effective relaxation time.
