'''Long scan times of 3D volumetric MR acquisitions usually necessitate ultrafast in vivo gradient-echo acquisitions, which are intrinsically susceptible to magnetic field inhomogeneities. This is especially problematic for contrast-enhanced (CE)-MRI ...'
'''The contrast properties and inherent insensitivity of spin echo based sequences to RF and magnetic field inhomogenities make them a particularly desirable addition to a clinical high field protocol, where susceptibility effects can be quite ...'
