Accordingly, interecho spacing is increased, which entails increased image blurring and, in multislice imaging, a significant reduction in the slice coverage for a given imaging time. In this work, a new method is developed by which the echo shift is induced by \u201csandwiching\u201d in time the readout gradient with a pair of small gradients of equal area and of opposite polarity. While data with non\u2010zero phase shifts between water and fat signals are collected as fractional echoes, no increase in echo spacing is necessary with the modified acquisition strategy, and increased time efficiency is therefore achieved. In order to generate separate water\u2010only and fat\u2010only images in data processing, a set of low\u2010resolution images are first reconstructed from the central symmetric portion (either 128 \u00d7 128 or 64 \u00d7 64) of the acquired multipoint Dixon data. High\u2010resolution images using all the acquired data, including some partial Fourier\u2010reconstructed images, are then phase demodulated using the phase errors determined from the low\u2010resolution images. The feasibility of the technique is demonstrated using a water and fat phantom as well as in clinical patient imaging.
