Susceptibility Weighted Imaging (SWI) uses susceptibility differences between tissues, (i.e. phase image) to enhance the contrast of the magnitude image, such as venography. However, quantitative value of image phase is hard to estimate due to its non-local and orientation dependent properties. Limitations such as restriction of resolution to achieve optimum phase shift in SWI arise from these reasons.
