ABSTRACT:
A 3DFT gradient-recalled echo pulse sequence is employed to acquire NMR data from which an MR angiogram is produced. A thin slab excitation is employed and this thin slab is incremented in slice-thickness steps through the volume of interest as the NMR data is acquired. Navigator echoes are acquired at each thin slab location to correct the NMR data for phase errors produced by the sliding slab technique.
