Abstract
The invention relates to a method of Dixon-type MR imaging of an object () placed in an examination volume of a MR device (). It is an object of the invention to provide a method that enables an improved Dixon water/fat separation in combination with a dual-acquisition gradient-echo imaging sequence. The method comprises the steps of: —subjecting the object () to a dual-acquisition gradient-echo imaging sequence comprising a series of temporally equidistant RF excitations, wherein one gradient echo is generated in each repetition time between successive RF excitations with the echo time alternating between a first and a second value (TE, TE), and wherein phase-encoding magnetic field gradients (P, S) are switched in each repetition time to sample a pre-defined region of k-space; —acquiring echo signals from the object (), wherein each gradient echo associated with either the first or the second echo time value (TE, TE) is sampled as a partial echo, and —reconstructing an MR image from the acquired echo signals, whereby signal contributions from water and fat are separated. Moreover the invention relates to an MR device () and to a computer program to be run on an MR device ().
