Synopsis

Keywords: Parallel Imaging, Parallel ImagingThree different models to reconstruct fat and water spiral images with parallel acquisition are compared in terms of computational efficiency and reconstruction quality. The best reconstruction is obtained with a full model requiring the most computational time, while the model with the fastest computational time results in some degradation of image quality. A third, preferred model preserves most of the image quality of the first model, with nearly the same speedup as the latter model.
