Many developments in the field of fast preclinical imaging are based on EVI sequences. We propose here an optimized protocol designed for preclinical in vivo imaging combining a quadrature surface coil with a zoomed Spin Echo EVI sequence using two orthogonal slice-selective adiabatic pulses (designated as ZEVIA) for volume selection. Brain coverage and time resolution are improved substantially without any drawbacks in the mouse brain in vivo at 7T.
