Density-weighted methods
WebSusceptibility-weighted imaging (SWI) is a new type of contrast in MRI different from spin density, T1, or T2 imaging. This method exploits the susceptibility differences between tissues and uses a fully velocity-compensated, three-dimensional, RF-spoiled, high-resolution, 3D-gradient echo scan. WebA weight function is a mathematical device used when performing a sum, integral, or average to give some elements more "weight" or influence on the result than other …
