Zusammenfassung
Motivation: To enable on-site environmental neuroscience, a mobile high-field MRI system is indispensable, and the stability of such mobile units is unclear.
Goals: To directly compare the reproducibility and reliability of a mobile 1.5T scanner, even after relocation, against a stationary 1.5T unit.
Approach: An in vivo study used seven subjects across four sessions, assessing B0/B1 homogeneity, structural (MP-RAGE) quality, and functional (EPI BOLD) tSNR and DMN consistency.
Results: The mobile system showed robust field stability and image quality comparable to the stationary unit. Variability from relocation was similar toinherent stationary variability, and the DMN was consistently extracted
