High dielectric materials based on calcium titanate suspensions in deuterated media can significantly improve clinically relevant scans at 7 Tesla with essentially zero background signal. Increases in the transmit field of up to 100% are measured in the cerebellum and temporal lobes. T1-weighted, FLAIR and especially T2-weighted scans show increased signal-to-noise and tissue contrast with thin dielectric pads surrounding the head.
