Patent ID: 7148685

Claim:
A method for producing an image with an MRI system, the steps comprising: a) performing a projection reconstruction pulse sequence with the MRI system which produces an rf excitation pulse at a frequency between the resonant frequencies of fat and water to acquire a first NMR signal that samples a first radial trajectory in k-space and to acquire a second NMR signal that samples a second radial trajectory in k-space; b) repeating step a) a plurality of times to sample a corresponding plurality of different radial trajectories in k-space; c) forming a first k-space data set with the acquired first NMR signals; d) forming a second k-space data set with the acquired second NMR signals; e) rotating the phase of k-space samples in one of said k-space data sets to form a phase shifted k-space data set; f) combining the phase shifted k-space data set with the other k-space data set to form a combined k-space data set; and g) reconstructing an image from the combined k-space data set.
