Phase images of pass-band bSSFP were investigated at multiple phase cycling (PC) angles at high field. Contrast between white matter and gray matter in phase images of pass-band bSSFP changed significantly with PC angle and was twice as high as that of phase images of gradient recalled echo at a specific PC angle. Phase images of pass-band bSSFP clearly demonstrated white matter and small structures presumed to be fiber bundles, which may not be easily visualized in the conventional methods. Phase imaging with pass-band bSSFP at multiple phase cycling angles may be a good anatomical imaging method at ultrahigh field.
