[Abstract] Susceptibility-weighted imaging is a high-spatial-resolution 3D MR imaging technique that is different from spin density, T1-, or T2-weighted imaging. SWI combines magnitude and phase images from the high-resolution, fully velocity compensated 3D gradient echo sequence based on the T2* weighted gradient echo sequence. It is particularly useful for detecting intravascular venous deoxygenated blood as well as extravascular blood products, it is superior to conventional gradient echo sequence in showing small cerebral veins or hemorrhage. In this article, we present a review focus on the principles and postprocessing techniques of susceptibility weighted imaging.
