Prospective motion correction enables highest resolution time-of-flight angiography at 7 T

摘要

PurposeHigher magnetic field strengths enable time-of-flight (ToF) angiography with higher resolution to depict small vessel pathologies. However, this potential is limited by the subject's ability to remain motionless. Even small-scale, involuntary motion can degrade the vessel depiction, thus limiting the effective resolution. The aim of this study was to overcome this resolution limit by deploying prospectively motion-corrected (PMC) ToF.
