KEYHOLE DIXON METHOD FOR FASTER FAT SUPPRESSION IN MRI

摘要

A method (10) of generating a magnetic resonance imaging (MRI) image by selectively suppressing one of two chemically shifted species. The method includes acquiring full data set (12) and a partial data set (14) with the TE set such that the magnetization of the second chemical species is 180° out of phase from its orientation in the first data set. The full (12) and partial (14) data sets are combined (16) to generate in MRI image that is perceptually equivalent to a multi-point Dixon image. The invention includes acquiring the minimum amount of data in the partial data set to generate an MRI image that is perceptually equivalent to a multi-point Dixon image.
