ABSTRACT:
In an MRI system a diffusion weighted fast spin echo (FSE) pulse sequence is employed to acquire data for producing an image. Each FSE pulse sequence is prefaced by a diffusion weighting pulse sequence, and components of the diffusion weighted spin magnetization that produce image artifacts are suppressed by a combination of gradient pulses and an RF pulse applied before the FSE pulse sequence is performed.
