Multiecho dixon fat and water separation method for detecting fibrofatty infiltration in the myocardium.
Conventional approaches for fat and water discrimination based on chemical-shift fat suppression have reduced ability to characterize fatty infiltration due to poor contrast of microscopic fat. The multiecho Dixon approach to water and fat separation has advantages over chemical-shift fat suppression: 1) water and fat images can be acquired in a single breathhold, avoiding misregistration; 2) f...
متن کاملCS-Dixon: Compressed Sensing for Water-Fat Dixon Reconstruction
Introduction: Water-fat separation is of interest in several MRI applications including fat suppression and fat quantification. Chemical shift imaging allows robust water-fat separation [1, 2], however the acquisition of multiple images results in prolonged scan time. Accelerated water-fat separation using compressed sensing (CS) was partly addressed in [3] by considering the separation as a sp...
متن کاملLinear phase-error correction for improved water and fat separation in dual-echo dixon techniques.
Large and spatially-linear phase errors along the frequency-encode direction may be induced by several common and hard-to-avoid system imperfections such as eddy currents. For data acquired in dual-echo Dixon techniques, the linear phase error can be more aggravated when compared to that acquired in a single echo and can pose challenges to a phase-correction algorithm necessary for successful D...
متن کاملRegularized iterative reconstruction for undersampled BLADE and its applications in three-point Dixon water-fat separation.
In MRI, the suppression of fat signal is very important for many applications. Multipoint Dixon based water-fat separation methods are commonly used due to its robustness to B(0) homogeneity compared with other fat suppression methods, such as spectral fat saturation. The traditional Cartesian k-space trajectory based multipoint Dixon technique is sensitive to motion, such as pulsatile blood fl...
متن کاملConsistent region-growing based Dixon water and fat separation for images with disconnected objects
Introduction: Successful water and fat separation in a Dixon technique [1] requires reliable and consistent correction of phase errors that are caused by the magnetic field inhomogeneity. Among different phase correction algorithms that have been published, region growing does not require a priori assumption on the spatial distribution of the field inhomogeneity and has been successful in many ...
