发明名称 MAGNETIC RESONANCE IMAGING METHOD
摘要 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 DELTA phi = - gamma r DELTA Bz tau 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 T2. The inventive method is characterized in that at least one rephasing pulse, which rephases the transversal magnetization, 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.
