Fast volume scanning with frequency-shifted BURST MRI.
We introduce a modified BURST imaging technique with reduced saturation effects and improved signal-to-noise ratio. The method applies a frequency shift to the RF excitation pulse on successive repetitions. It allows collection of 3D datasets of human brain within a few seconds, on a standard clinical scanner at 1.5 Tesla.
