发明名称 Bildgebungsverfahren
摘要 The invention relates to an imaging method for examining substances, wherein a precession of at least one nuclear spin having an additional phase angle DELTA phi = - gamma r DELTA Bz tau relative to an already existing precession is generated by indirect nuclear spin-nuclear spin interaction in an external magnetic field with the purpose of spreading perpendicular magnetization vertical to the magnetic field so that relaxation of perpendicular magnetization occurs within a relaxation time T2*. According to the invention, the method is characterized in that the relaxation is recorded in the form of at least one high resolution image directly after the excitation pulse using echo-planar-imaging and in that more images are recorded at lower resolution thereafter.
