Susceptibility weighted imaging(SWI) is a method using magnetizable rate differences between different organizations to attain image contrast. The deoxidizing hemoglobin of the vein is paramagnetic and is a good endogenous enhancement contrast agent, so SWI has special sensitivity for the veins. SWI can detect less than an individual element of the venule (200~300μm). The application of this new technology will improve the detection rate of delitescent brain diseases greatly. Understanding of the normal anatomy structure is necessary for disease diagnosis.This article reviews the principle and technology of the SWI for the venous system and the related clinical research, combined with the results of microvascular perfusion method and magnetic resonance venography (MRV) technology on the internal cerebral vein (ICV) and its tributaries, in order to explore the feasibility of using SWI to establish the atlas of ICV and its tributaries and to provide guidance for clinical diagnosis and treatment
