Abstract
A single sequence for the formation of a plurality of images of the same selected nuclei but with each image having a different contrast characteristic is disclosed. MRI signals are acquired during the first time interval which comprises a plurality of first intervals with each of the first intervals being substantially the same. During the first time interval, the selected nuclei are phase encoded by a different magnetic phase encoding gradient. The sequence continues to acquire a second plurality of MRI signals from the same plurality of selected nuclei. The second time interval comprises a plurality of second intervals different from the first intervals. During the second interval, the selected nuclei are phase encoded by a different magnetic phase encoding gradient but with the magnetic phase encoding gradient being the same as or a subset of those during the first time interval. The data from the first and second plurality of MRI signals are regrouped and portions are reused to form a plurality of regrouped data sets. Each of the regrouped data sets is then fourier transformed to produce a plurality of images of the selected nuclei. Each image is of the same plurality of selected nuclei but with different contrast characteristics.
