Abstract
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.
