An MRI apparatus for imaging 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. |
