This study serves as a short\u2010term feasibility and system commissioning report, investigating the reliability and repeatability of two mobile 1.5 T MRI scanners compared to a stationary 1.5 T reference. To evaluate the technical impact of scanner relocation and mobile housing, a comprehensive protocol was implemented: five healthy subjects underwent 10 scans each (\n                    <jats:italic>N<\/jats:italic>\n                    \u2009=\u200950 total sessions) across three 1.5 T systems (one stationary; two mobile). The protocol employed a test\u2013retest design with participant repositioning on each measurement day. Stability was assessed through longitudinal fBIRN phantom scans and human imaging of magnetic field homogeneity (\u0394B\n                    <jats:sub>0<\/jats:sub>\n                    ), RF flip\u2010angle mapping (B\n                    <jats:sub>1<\/jats:sub>\n                    <jats:sup>+<\/jats:sup>\n                    ), structural MP\u2010RAGE, and functional EPI\u2010BOLD. Initial commissioning results demonstrated that short\u2010term relocation and mobile operation did not compromise hardware performance. Phantom QA showed stable tSNR and minimal signal drift. In human subjects, magnetic field stability (\u0394B\n                    <jats:sub>0<\/jats:sub>\n                    ) and B\n                    <jats:sub>1<\/jats:sub>\n                    <jats:sup>+<\/jats:sup>\n                    distributions were equivalent across systems, with Bland\u2013Altman plots confirming no systematic bias following transit. Structural MP\u2010RAGE voxel\u2010intensity distributions and tissue volumes were highly consistent, with ICCs between 0.99 and 1 for estimated WM and GM volumes. This technical validation study demonstrates the short\u2010term feasibility of utilizing mobile 1.5 T platforms for high\u2010quality neuroimaging. The results confirm that current mobile shielding and stabilization technologies effectively mitigate the environmental challenges of transit, establishing a reliable baseline for future longitudinal research in remote or underserved settings.\n                  <\/jats:p>","DOI":"10.1002\/nbm.70310","type":"journal-article","created":{"date-parts":[[2026,6,2]],"date-time":"2026-06-02T02:40:30Z","timestamp":1780368030000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["MRI Goes Mobile: Assessing the Reliability and Repeatability of a Mobile vs. Stationary 1.5 T MRI for Functional Neuroscience Studies"],"prefix":"10.1002","volume":"39","author":[{"given":"Christoph Stefan","family":"Aigner","sequence":"first","affiliation":[{"name":"Max Planck Research Group MR Physics Max Planck Institute for Human Development  Berlin Germany"},{"name":"Physikalisch\u2010Technische Bundesanstalt (PTB)  Berlin Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4709-7797","authenticated-orcid":false,"given":"Caroline Garcia","family":"Forlim","sequence":"additional","affiliation":[{"name":"Center for Environmental Neuroscience Max Planck Institute for Human Development  Berlin Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Davide","family":"Santoro","sequence":"additional","affiliation":[{"name":"Max Planck Research Group MR Physics Max Planck Institute for Human Development  Berlin Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nils C.","family":"Bodammer","sequence":"additional","affiliation":[{"name":"Max Planck Research Group MR Physics Max Planck Institute for Human Development  Berlin Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R\u00fcdiger","family":"Br\u00fchl","sequence":"additional","affiliation":[{"name":"Physikalisch\u2010Technische Bundesanstalt (PTB)  Berlin Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sonja","family":"Sudimac","sequence":"additional","affiliation":[{"name":"Center for Environmental Neuroscience Max Planck Institute for Human Development  Berlin Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katharina","family":"Schmalen","sequence":"additional","affiliation":[{"name":"Center for Environmental Neuroscience Max Planck Institute for Human Development  Berlin Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebastian","family":"Schr\u00f6der","sequence":"additional","affiliation":[{"name":"Scientific Technology &amp;
