Combining highly parallel array coils, magnetic field monitoring, and high gradient strength provide a complementary approach to enhance diffusion-weighted imaging (DWI). A 64-channel receive brain array with an incorporated 16-channel field camera system was developed to be used with 300 mT/m gradients from the 3T Connectom scanner. The increased signal-to-noise ratio (SNR) and implemented parallelism was highly beneficial, and will improve SNR-starved high-b value DWI acquisitions, while the magnetic field monitoring data successfully corrected the images from blurring, aliasing and distortions.
