Abstract:

At high magnetic fields, RF inhomogeneity becomes substantial and unavoidable at high magnetic fields due to its dependence on the sample. It leads to intensity/contrast nonuniformities, which cause difficulties in image interpretation and segmentation. In this paper, we report an interesting observation that the FLASH sequence can be insensitive to RF inhomogeneity when the same coil is used for both transmission and reception and a proper flip angle is used.
