1. A magnetic resonance imaging apparatus comprising:
- an imaging data acquiring unit which acquires a plurality of 3-dimensional imaging data each corresponding to mutually different traveling time of inflowing blood flowing into an imaging region including myocardium in synchronization with a heartbeat without administration of a contrast medium, by applying a spatial selective excitation pulse plural times for distinguishably displaying the inflowing blood and by changing a time interval from application timing of the spatial selective excitation pulse to acquisition timing of the imaging data;
a blood flow image generating unit which generates a plurality of blood flow image data corresponding to the mutually different traveling time of the inflowing blood based on the plurality of imaging data; and
a cardiac function analysis unit which allows obtaining blood flow information indicative of cardiac function of the myocardium based on the plurality of blood flow image data.

Abstract
An MRI apparatus includes an imaging data acquiring unit and a blood flow information generating unit. The imaging data acquiring unit acquires imaging data from an imaging region including myocardium, without using a contrast medium, by applying a spatial selective excitation pulse to a region including at least a part of an ascending aorta for distinguishably displaying inflowing blood flowing into the imaging region. The blood flow information generating unit generates blood flow image data based on the imaging data.
