Use of magnetic susceptibility effect as an image contrast is relatively new technique that has proven useful for evaluation iron containing tissues, cerebral microvasculature, and pathologic processes resulting in susceptibility changes (hemorrhage, metastasis, traumatic brain injury, metabolic disorders). The purpose of this work is to evaluate SWAN (T2Star Weighted ANgiography) a new susceptibility enhanced imaging sequence [1], and compare this technique to conventional gradient echo imaging.
