Learning objectives
Susceptibility-Weighted Imaging (SWI) is a relatively new magnetic resonance imaging(MRI) sequence relying on susceptibility differences between adjacent tissues to produce an image.
It is extremely sensitive for detection of blood products (hemosiderin,
ferritin),deoxygenated blood,
calcium,
iron,
and small vein depiction.
Little information is available in the literature to describe common findings seen using this imaging sequence.
This presentation is an comprehensive review of appearances across the spectrum of brain pathology encountered in routine clinical practice.
1) To review the history and development of SWI
2) Demonstrate the sequence technique,
physics behind the technique
3) Composition of the SWI final image
4) Review application of this novel technique in various CNS pathologies,
in particular vascular disorders.
5) SWI at 3T and its future applications
