Webcohorts of fat and water that are the root of chemical-shift artifacts and the basis for fat-water separation techniques [3]. Fat-Water Separation In 1984, Dixon [4] proposed a new tech-nique for fat saturation based on the differing frequencies of fat and water. Because of their slightly differing local magnetic fields, fat WebJun 18, 2024 · Fat-water swapping is an artifact specific to chemical shift encoded MRI and so-called Dixon methods. It is more frequent using the 2-point than the multi-point (> 2) Dixon method. Actually, fat-water swapping on the 2-point Dixon sequences partly triggered the development of the multi-point techniques. how tall is 5 ft 4 inches in cm
