The post-processing of susceptibility weighted imaging and clinical application

Susceptibility weighted imaging(SWI)is a new imaging technology based on the susceptibility difference of different tissues,it can make better contrast between different tissues.Compared with the traditional magnetic resonance imaging(MRI),SWI provides the unique superiority for the vein imaging,and can be used on the research of cerebral tumor,cerebral hemorrhage or other nidus with veins and improve the diagnosis on these diseases effectively.In order to show the vein blood vessel clearly using SWI,complicated image post-processing technology is needed.This review focuses on SWI,its clinical application and the related image post-processing technology.
