Compressed sensing for chemical shift-based water-fat separation.

Multi echo chemical shift-based water-fat separation methods allow for uniform fat suppression in the presence of main field inhomogeneities. However, these methods require additional scan time for chemical shift encoding. This work presents a method for water-fat separation from undersampled data (CS-WF), which combines compressed sensing and chemical shift-based water-fat separation. Undersam...

Chemical shift-based water/fat separation: comparison of fitting models

INTRODUCTION Quantitative water/fat separation in MRI requires careful modeling of the acquired signal. Multiple signal models have been proposed in recent years, but their relative performance has not yet been established. This abstract presents a comparative study of 12 signal models for water/fat separation. The models were selected according to three criteria: magnitude or complex fitting [...

Quantification of susceptibility-induced fat resonance shift on chemical shift-based water/fat separation of skeletal muscle

Introduction: The quantification of skeletal muscle fatty infiltration is important in assessing risk factors for metabolic abnormalities (like obesity and diabetes) [1] and in monitoring the progression of myopathies [2]. Muscular fat includes intramyocellular lipids (IMCLs) that are approximated as spherical droplets within myocytes and extramyocellular lipids (EMCLs) that are approximated as...

Cardiac Imaging with Chemical Shift Based Water-Fat Separation at 3T

Introduction Chemical shift based water-fat separation techniques have been demonstrated for 1.5T cardiac imaging of several pathologies, including fatty infiltration of chronic infarction; arrhythmogenic right ventricular cardiomyopathy (ARVC); fatty tumors; and conditions such as myocarditis and pericarditis [1-4]. Higher field strengths (3T) are now often used in cardiac MRI due to improved ...
