objective: to explore the clinic and application value of susceptibility weighted imaging(SWI). Methods: Recent domestic and foreign relative literatures on clinical value of SWI were retrospectively analyzed. Result: As a kind of new clinical noninvasively magnetic resonance imaging(MRI) examination technique which was extremely sensitive to magnetic susceptibility, SWI played an important role in diagnosis of various diseases,especially had a more particular clinical value in diagnosis of cerebral vascular disease,trauma,cerebral tumors,and degenerative nerve disease,with a large potential in functional MRI. Conclusion: SWI is a type of MRI examination technique,which is sensitive to paramagnets,such as deoxygenated blood,iron and calcium,and used in neurological disorders widely.
