Self-navigated IDEAL Water-Fat Separation
Introduction: IDEAL (Iterative Decomposition of water and fat with Echo Asymmetry and Least squares estimation) has proven to be a robust method to achieve uniform water-fat separation [1]. Recently, it has been adopted in quantitative analysis of adiposity as well [2]. However, the three-point acquisition prolongs the scan time, which leads to increased susceptibility to motion. The presence o...
متن کاملPreliminary results of IDEAL fat/water separation at 9.4T
Introduction An iterative Dixon algorithm (IDEAL) [1] was established for efficient fat/water-separation during the last years. Here the method was executed invivo on a dead rat on 9.4T in order to verify the high-field performance of IDEAL. Data were acquired with a vendor supplied 3D multigradientecho sequence. Method Experiments were performed on a 9.4T Bruker Biospec 94/20 small animal scan...
متن کاملSingle-image water/fat separation
Introduction In MRI, fat can be hard to distinguish visually from pathology or contrast agent, due to its high signal intensity in many imaging sequences. Water and fat separation techniques provide an alternative to conventional fat suppression, and are also of interest in body composition applications. Dixon techniques [1] utilize the property of chemical shift to separate water and fat with ...
متن کاملMulti-echo IDEAL Cardiac Water-Fat Imaging
Introduction In cardiac magnetic resonance imaging, separation of water and fat signals is important for improved visualization of enhancing myocardium and pericardial disease, as well as direct visualization of fat in pathologies such as arrythmogenic right ventricular cardiomyopathy (ARVC), fatty tumors, and fatty infiltration of chronic myocardial infarctions. Fat can appear similar to slow ...
