방사선사나라 Radiographer Nara
[MRI] (영/한) chemical shift artifact/ 화학적 이동 인공물
(영어/영문/English) Chemical shift artifact? The chemical structure of fat and water is different, and the difference in precession frequency is proportional to the intensity of the main magnetic field. Fat and water have a chemical shift of 3.5 part per million (ppm) and fat resonates at a lower frequency than water. At a frequency of 0.5 Tesla, it resonates at a frequency with a difference of 74 H..
