Susceptibility Weighted Imaging (SWI) method is commonly used for Magnetic Resonance (MR) venography. The difference between SWI and conventional GRE imaging is that phase information of signal is incorporated to enhance contrast of image. The phase can provide excellent contrast between venous blood vessels and other tissues with susceptibilities that are different from the background tissue. Although SWI is very powerful technique, SWI technique still has some weaknesses, regarding a trade-off between the gain of venous contrast and the loss of SNR. In this study, we propose a new approach to obtain high-contrast and high-SNR SWI venography with multiple echo datasets.
