Abstract
The invention relates to an imaging method for examining substances which contain atoms with an indirect nuclear spin-nuclear spin interaction. At least one excitation impulse produces a precession of at least several nuclear spins with an additional phase angle &Dgr;&phgr;=−&ggr; &Dgr;B &tgr; in relation to an already existing precession in an outer magnetic field so that a transversal magnetization spreads out perpendicularly in relation to the outer magnetic field whereby effecting a relaxation of the transversal magnetization with relaxation times T . The inventive method is characterized in that at least one rephasing pulse, which rephases the transversal magnetiztion, is applied after the excitation pulse and after a recording of at least one highly resolved image, and in that additional images are subsequently recorded with a lower resolution.
