<P>PROBLEM TO BE SOLVED: To make a visual mutual comparison of different images taking labor and inaccurate in detail unnecessary. <P>SOLUTION: In this magnetic resonance image evaluating method, especially the magnetic resonance image evaluating method for discriminating and demarcating critical cerebral tissue, a mismatch image is formed by superposing a perfusion-emphasized magnetic resonance image of the same body region on the diffusion-emphasized magnetic resonance image. <P>COPYRIGHT: (C)2005,JPO&NCIPI
