We present an analysis of the SNR gains produced in high-b-value diffusion-weighted imaging using a novel 3T system with ultra-high, 300 mT/m maximum gradient amplitude (MAGNETOM Skyra CONNECTOM, Siemens Healthcare). Results are presented for both human and phantom studies with b=10k and b=20k, comparing SNR increases as a function of maximum gradient strength ranging from 40 mT/m (standard on clinical systems) to 300 mT/m.
