ABSTRACT:
A magnetic resonance imaging apparatus is provided which generates a plurality of echoes by applying a 90.degree. RF pulse for magnetically exciting spins and subsequently repetitively applying a 180.degree. RF pulse for inverting the phase of the magnetized spin. In this apparatus, a pulse sequence is so performed as to enable any specific interval, out of an interval from the application of a 90.degree. RF pulse until a first echo is obtained and intervals each-between sequential adjacent two echoes, to be made to correspond to a 3 or more odd multiple of any other intervals.
