Zusammenfassung: | The invention relates to a method of MR imaging of at least a portion of a body (10) of a patient positioned in an examination volume of a MR device (1). It is an object of the invention to provide a method that enables improved fat saturation. The method of the invention comprises the steps of:-subjecting the portion of the body (10) to a calibration sequence comprising RF pulses and switched magnetic field gradients controlled in such a manner that a calibration signal data set is acquired by means of a multi-point Dixon technique at a first image resolution;-deriving calibration parameters from the calibration signal data set;-controlling the MR device (1) according to the derived calibration parameters;-subjecting the portion of the body (10) to an imaging sequence comprising RF pulses and switched magnetic field gradients controlled in such a manner that a diagnostic signal data set is acquired at a second image resolution which is higher than the first image resolution; and-reconstructing a diagnostic MR image from the diagnostic signal data set. Moreover, the invention relates to a MR device (1) for carrying out the method and to a computer program to be run on a MR device (1). |
