High field MRI has introduced new challenges for DWIBS body imaging with respect to susceptibility artefacts, fat suppression, dielectric shading, and longer acquisition times. Dual-source parallel RF excitation has been shown to allow for a more homogeneous excitation. Therefore, we evaluated the effect of this technique on DWIBS in 40 patients. Shorter acquisition times by 33%, significantly improved signal homogeneity and fat suppression, and reduced dielectric shading without influencing ADC values was found by using parallel RF excitation in DWIBS at 3.0 T.
