1. A magnetic resonance (MR) imaging method comprising the steps of:

  • applying a slice-selecting gradient field to a biological body under medical examination located in a static field;

    applying a spin excitation pulse to the biological body while said slice-selecting gradient field is being applied thereto;

    applying a refocusing pulse to the biological body after the application of said slice-selecting gradient field;

    applying to the biological body, a rephasing gradient field having the same polarity of that of said slice-selecting gradient field Just after the application of said refocusing pulse; and

    acquiring a spin echo signal induced in a slice of the biological body excited by said spin excitation pulse to obtain MR information of said excited slice.
