Abstract
A water and fat image are acquired using a pulse sequence in which NMR signals for one image data set are acquired with a readout gradient of one polarity and NMR signals for the other image data set are acquired with a readout gradient of the opposite polarity. A misalignment of fat signals caused by chemical shift is corrected by calculating separate water and fat image data sets in k-space and then transforming them to real space images.
