Abstract

The invention is directed to a method for acquiring a magnetic resonance image dataset (10) of an object (U), using an imaging protocol in which several k-space lines (22) are acquired in one echo train (45), wherein an echo train may comprise one or several sub echo trains (42, 48), the imaging protocol comprising a plurality of echo trains (45). A set of additional k-space lines (24) within a central region (16) of k-space is acquired a number of times per echo train (45), wherein the number is greater than 1, in order to detect movement of the object (U) during the echo train. The sets of additional k-space lines (24) are acquired at pre-determined positions within the echo trains. The invention is also directed to a method for generating a motion-corrected magnetic resonance image dataset from the dataset (10) thus acquired, a magnetic resonance imaging apparatus (1) and a computer program.
