Swi susceptibility weighted imaging

Splet08. jul. 2024 · Susceptibility-weighted imaging (SWI) is a newly developed MRI technique. SWI can differentiate the magnetic susceptibility effect of different components like blood products, deoxygenated blood, calcium, and iron. SpletSusceptibility Weighted Imaging (SWI)* We have developed a new type of contrast in MRI different from spin density, T1, or T2 imaging. This new method exploits the susceptibility differences between tissues. We refer to this method as Susceptibility Weighted Imaging*.
