Magnetic resonance method and device for suppressing a signal from a chemical shift component in a longitudinal relaxation time weighted magnetic resonance image

摘要

An improved MRI sequence for suppressing a signal from a chemical shift component avoids image artifacts due to relatively large rf fields inhomogeneities as may be caused by using linearly polarized rf fields by selectively inverting the chemical shift component by means of an adiabatic fast passage rf pulse prior to spin echo excitation.
