ABSTRACT:
A magnetic resonance imaging method and device (1) allow for automatic quantitative motion evaluation of a part of an object (4). The pulse and gradient sequence (tsq1, tsq2), which achieves a high contrast tagging grid, is a stimulated echo based tagging sequence, the tagging section (TAG) being applied before the imaging section (img) or being integrated (G.sub.9, G.sub.10) in the imaging section (img).
