Abstract
It is also referred to as chemical shift imaging. Varying the TE of T1-w GRE sequence in-phase (fat and water protons in phase) and out-of-phase (net cancellation of signal: drop of signal intensity in fat-containing areas/lesions) images may be obtained which provide information on parenchymal and lesion fat content (Fig. 1). Opposed-phase images have a shorter TE, normal liver is brighter, and fat-containing areas/lesions demonstrate decrease in signal intensity.
