Improved Detection of fMRI Activation in the Cerebellum at 7T with Dielectric Pads Extending the Imaging Region of a Commercial Head Coil

摘要

BACKGROUNDThere is growing interest in detecting cerebro-cerebellar circuits, which requires adequate BOLD contrast and signal-to-noise ratio (SNR) throughout the brain. Although 7T scanners offer increased SNR, coverage of commercial head coils is currently limited to the cerebrum.
