1025 Multi-echo dixon fat and water separation method for detecting fibro-fatty infiltration in the myocardium
Year: 2008
Type: article
Abstract: The ability of MRI to discriminate between water and fat is important in tissue characterization. Conventional approaches to fat and water discrimination based on fat suppression are commonly used to characterize masses, however, have reduced ability to characterize fatty infiltration due to the poor contrast of microscopic fat and partial volume effects. Multi-echo Dixon methods [ 1 , 2 ] for fat and water separation provide a sensitive means of detecting small concentrations of fat with improved contrast. These methods are applied to the detection of fibro-fatty infiltration observed in chronic MI [ 3 ] as well cases of suspected ARVC/D [ 4 ]. In the present study, fat and water separation has been implemented both pre-contrast as well as applied to late enhancement using a multi-echo PSIR-GRE sequence.
