MAGNETIC RESONANCE TOMOGRAPHY WITH WATER AND FAT SEPARATION BY DICKSON METHOD Russian patent published in 2020 - IPC G01R33/48 

FIELD: magnetic resonance imaging.

SUBSTANCE: essence of the invention consists in the fact that the object is exposed to the first visualizing sequence containing a series of refocusing RF pulses, wherein in each time interval between two successive refocusing RF pulses a single echo signal is generated, echo signals are received from the object in the first received frequency band using unipolar gradients of the reading magnetic field, subjecting the object to a second rendering sequence which contains a series of refocusing RF pulses, wherein in each time interval between two successive refocusing RF pulses, generating a pair of echo signals, obtaining said pair of echo signals from object in second received frequency band using bipolar gradients of reading magnetic field, wherein the second received frequency band is higher than the first received frequency band, and performing the MR image reconstruction from the received echo signals, wherein contributions of signals from protons of water and fat protons are separated.

EFFECT: possibility of efficient separation of water and fat in combination with TSE-data collection.
