摘要： A method for identifying nuclear magnetic spectra from spatially selectable regions of an examination subject obtains an optimally unattenuated FID signal by the steps of cancelling the magnetization present due to the fundamental magnetic field in volume regions of the examination subject which are not to be evaluated, subjecting the examination subject to a non-selective RF read-out pulse which deflects at least the nuclear spins in the examination regions to be selected, and reading out the resulting FID signal following the non-selective RF read-out pulse. The selected examination region is determined by the transmission/reception characteristics of the coil which receives the FID signal minus the selectively saturated volume region.

摘要： For improving the spectral resolution and/or the signal-to-noise ratio of a nuclear magnetic resonance apparatus for examining first types of atomic nuclei that are nuclear-magnetically coupled to second types of atomic nuclei, signals are additionally emitted on the resonant frequency of the second type of atomic nucleus during the examination of the first type of atomic nucleus. To this end, the nuclear magnetic resonance apparatus includes a reception channel and only one transmission channel for both resonant frequencies. The transmission channel contains a respective synthesizer for each resonant frequency, which define the transmission frequency and contains a modulator unit shared in common by both resonant frequencies.

摘要： 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.
