A magnetic resonance imaging apparatus includes a scan section which
executes a diffusion weighted imaging pulse sequence on an imaging area
of a subject within a static magnetic field space thereby to acquire
magnetic resonance signals, an image generating part which generates an
image with respect to the imaging area, based on the magnetic resonance
signals acquired by the scan section, a display unit which displays the
image generated by the image generating part on a display screen thereof,
and a window setting part which sets a window level and a window width at
the time that the display unit displays the image, based on diffusion
parameters calculated from the magnetic resonance signals acquired by the
scan section. The display unit displays the image on the display screen
by the window level and the window width both set by the window setting
part.
