Fat quantification by use of phase change in dual-echo magnetic resonance imaging.

The demand for measurement of visceral fat in medical checkups is increasing because of attention to central obesity. Computed tomography is widely used for this purpose, but carries risks associated with radiation exposure. Fast imaging with a dual-echo technique acquiring water and fat signals both in-phase and out-of-phase using magnetic resonance imaging is desirable, but not all scanners are capable of this technique.
