Influence and Compensation of Fat Signal Dephasing and Decay in Two-Point Dixon Imaging

Fat has a complex spectral composition, which causes its signal to dephase and decay noticeably even over short intervals. The influence of these effects on the extent of fat suppression reached in two-point Dixon imaging is evaluated in this work and is found to strongly depend on the choice of echo times. Moreover, it is shown how more complex spectral models of fat may be incorporated into a generalized two-point Dixon method, with which a more uniform degree of fat suppression is achieved across a range of relevant echo times.
