An MRI apparatus for imaging of a bodily fluid flowing inside a subject
includes a gradient coil which applies gradient pulses to the subject, a
transmission coil which transmits RF pulses to the subject, and a control
part which controls the gradient coil and the transmission coil. The
control part controls the gradient coil and the transmission coil in
order to: saturate longitudinal magnetization of the bodily fluid in a
field of saturation positioned on an upstream flow of the bodily fluid
during a saturation period, invert the direction of longitudinal
magnetization of the bodily fluid in an imaging field of view positioned
on an downstream flow of the bodily fluid during an inversion period
following the saturation period, and acquire MR signals from the bodily
fluid in the imaging field of view during a data acquisition period
following the inversion period.
