METHOD AND INSTRUMENT FOR MAGNETIC RESONANCE IMAGING

摘要

PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging method for excellently separating a moisture signal from a fat signal at high speed. SOLUTION: Echo signals 141 and 142 are obtained concerning one-time irradiation of an exciting pulse 101 by the polarity inversion of a reading inclination magnetic field pulse. Then the signals 141 and 142 are added/subtracted which are measured by the in-phase timing and the out-of-phase timing of phases in the signals of tissues 1 and 2 having different resonance frequencies.
