The purpose of this study was to determine which sequences can be immediately deployed for brain and spine imaging on a low-field 0.55T MRI system, with the goal of generating optimized protocols which can be used at other sites for routine clinical neuroimaging. The image quality of 174 brain and spine images was rated by two neuroradiologists. Almost all brain (T1w, T2w, FLAIR, DWI, MRA) and spine (T1w, T2w, DIXON) sequences received image quality scores corresponding to acceptable diagnostic image quality. These sequences form numerous neurological MRI protocols, which based on these results could be collected at 0.55T.
