The magnetic susceptibility effect often obtained in clinical NMR imaging is
analysed and a measurement method of the magnetic susceptibility effect is proposed. The
method of extraction of the susceptibility effect alone in high-field NMR imaging where
usually the chemical shift and main magnetic field inhomogeneity effects are intermingled
with the susceptibility effect is discussed. The proposed susceptibility measurement uses
the susceptibility weighted echo-time encoding technique (SWEET) to modulate the NMR
signal as a function of echo time with which the image intensity can be weighted. Both
phantom-oriented physical experiments and human volunteer experiments were performed
to demonstrate the usefulness of the technique for human imaging.
