1. A method for acquiring data from a subject with a magnetic resonance imaging (MRI) system, the steps comprising: a) performing a three-dimensional pulse sequence with the MRI system to acquire NMR data which samples points in a line of k-space; b) repeating step a) a plurality of times to acquire NMR data that samples points throughout a three-dimensional region of k-space; c) repeating step a) a plurality of times to acquire NMR data that samples points in a two-dimensional plane within the three-dimensional region of k-space; d) reconstructing a two-dimensional image from the NMR data that samples points in the two-dimensional plane; and e) reconstructing a three-dimensional image from the NMR data that samples points throughout the three-dimensional region of k-space.
