PROBLEM TO BE SOLVED: To provide an MRA which improves both of time resolution and space resolution without using a contrast agent. SOLUTION: Immediately after inverting a spin of an imaging area CS by a first inversion pulse, a second inversion pulse with a tag is applied together with a selectively-excited gradient of magnetic field. By this, the spin of a tag area RG<SB>A1</SB>as selected area is inverted and the tag is attached. Subsequently, after a fixed TI time elapses, scanning is started to receive an echo signal. The change of the space position of the tag area is ordered, and a series of the processing are repeated. A plurality of images (IM<SB>rec1</SB>-, IM<SB>int1</SB>-, IM<SB>fin1</SB>-) are generated from the echo signal collected associated with each scanning. The generation procedure includes a masking processing, a maximum intensity projection or the like. A high signal part from a blood flow with the tag is depicted on the plurality of images and these images are shown, for example, by a cine display. COPYRIGHT: (C)2011,JPO&INPIT
