ABSTRACT:
A method for chemical shift imaging is disclosed. A first radio frequency pulse at the resonance frequency of hydrogen and second radio frequency pulse at the resonance frequency of atoms to be examined are applied. Spatial resolution is obtained by phase encoding gradients. The repetition time is shorter than the spin-lattice relaxation time. The first radio frequency pulse at the resonance frequency of hydrogen causes a Nuclear Overhauser Effect enhancement of the resonance line of the atoms to be examined.
