Additionally, reference navigators were distributed along the imaging echo train to test a within\u2010echo train correction (within\u2010ET) with contrast\u2010matched models, enabling more frequent geometry updates. The methods were evaluated in instructed motion experiments and in high\u2010resolution scans at 7T.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Artifacts caused by instructed abrupt motion were clearly reduced in scans with servo navigation for both sequences using the before\u2010prep correction.
