Susceptibility Weighted Imaging FAQs
- What is susceptibility weighted imaging?
- How do I acquire susceptibility weighted images and mIPs in humans on GE 3.0T?
- What are the latest updates on the SWI processing software?
Susceptibility Weighted Imaging (SWI) is a relatively new data acquisition and processing technique that provides the high resolution mapping of the brain’s venous vasculature.
It combines the phase and magnitude data to generate an image whose contrast is sensitive to deoxygenated blood and iron content.
The data acquisition and post processing steps needed to generate SWI images and the minimum Intensity Projection (mIP) are available on this page as beta.
The mIP is a two-dimensional top down view of a stack of processed SWI images where each pixel corresponds to the minimum signal intensity.
The following figure is an example mIP generated by the in-house SWI post processing program.
The SWI protocol is available both on 3TE and 3TW scanners.
The protocol is under site/head/SWI-CFMRI.
A detailed instruction manual is available here.
