Of all the various techniques used for imaging just water and fat, the most common one is based on selective frequency excitation of water and fat tissues. This technique is known as Fat Saturation. Esaote’s continuous research for more specialized sequences together with high-speed acquisition, has consequently led to developing a technique for separating water and fat in a single scanning, combined with an appropriately optimized correction of the static magnetic field inhomogeneity. This sequence has been called XBone.
