Abstract

A new algorithm is presented that provides separate water, fat, and B~0~ images utilizing the in‐phase and opposed‐phase acquisitions of the two‐point Dixon (2PD) method. The accuracy of the extended method (E2PD) compares favorably with the three‐point Dixon (3PD) method, and the acquisition requires 2/3 the 3PD scan time. Slightly increased mismapping may occur in pixels containing an admixture of water and fat due to reduced SNR in the B~0~ field map compared with the 3PD method.

## Abstract A two‐point Dixon technique using a novel phase‐correction algorithm and commercially available dual‐echo fast gradient‐echo pulse sequence is presented. The phase‐correction algorithm determines the directional rather than phase distribution of signals due to field inhomogeneities. Spe
