SWI - Susceptibility Weighted Imaging

Susceptibility Weighted Imaging (SWI) is a specialized MRI technique that enhances the visibility of certain tissues and structures within the brain, particularly those containing blood products or mineral deposits. It takes advantage of the magnetic susceptibility differences between tissues to create high-resolution images that are sensitive to blood, iron, and other substances with paramagnetic properties. SWI is particularly useful for detecting small hemorrhages, microbleeds, venous structures, and calcifications in the brain. It can aid in the diagnosis and evaluation of various neurological conditions, including traumatic brain injury, stroke, cerebral microangiopathy, and neurodegenerative diseases.
