Measurement of fat/water ratios in rat liver using 3D three-point dixon MRI.
Hepatic steatosis, or fatty liver, is commonly observed during the animal phase of drug safety studies. A noninvasive three-dimensional (3D) three-point Dixon method was used to quantitatively evaluate the fatty livers of rats induced by an experimental microsomal transfer protein (MTP) inhibitor, in an effort to develop a safety biomarker that could be translated to human studies. The method w...
متن کاملQuantification of epicardial fat volume using cardiovascular magnetic resonance imaging
Background A growing body of data has demonstrated a direct relationship between epicardial fat volume(EFV) and cardiovascular diseases. In fact, EFV has been shown to be an independent predictor of coronary atherosclerosis and atrial fibrillation. Currently, there is no standard protocol for assessing EFV using cardiac magnetic resonance imaging (CMR). Quantification of peri-ventricular EFV ut...
متن کاملComparison of Dixon Methods for Fat Suppression in Single Breath-Hold 3D Gradient-Echo Abdominal MRI
Introduction A variety of Dixon methods has been proposed over the last years that permit a robust fat suppression in inhomogeneous magnetic fields [1-3]. Apart from different strategies to separate water and fat signal, the individual methods are mainly characterized by the number of echo times, or points, that they rely on and by the constraints that they impose on these echo times. In this w...
متن کاملCorrection of Fat-Water Swaps in Dixon MRI
The Dixon method is a popular and widely used technique for fat-water separation in magnetic resonance imaging, and today, nearly all scanner manufacturers are offering a Dixon-type pulse sequence that produces scans with four types of images: in-phase, out-of-phase, fatonly, and water-only. A natural ambiguity due to phase wrapping and local minima in the optimization problem cause a frequent ...
متن کامل3D-Dixon cardiac magnetic resonance detects an increased epicardial fat volume in hypertensive men with myocardial infarction
PURPOSE Using a three-dimensional ECG- and respiratory navigator gated magnetization prepared mDixon-sequence (3D-Dixon) we quantified epi- and pericardial fat volumes (EFV, PFV) in hypertensive men compared to a healthy control group and related the amount of fat volumes in hypertensive men to the presence of coronary artery disease (CAD) and myocardial infarction (MI). MATERIALS AND METHODS...
