The present invention provides an MRI apparatus with selective saturation
without affection to the integral value of gradient magnetic field in
1TR. The MRI apparatus comprises a signal acquisition device for applying
static field, gradient magnetic field pulses and RF pulses to an object
to acquire magnetic resonance signals therefrom, an image reconstruction
device for reconstructing an image based on the magnetic resonance
signals acquired, and a controller device for controlling both device.
The controller device directs the signal acquisition device to apply
gradient magnetic field pulses and RF pulses for selective saturation for
a number of times prior to applying gradient magnetic field pulses and RF
pulses for signal acquisition.
