High-Resolution Susceptibility-Weighted Imaging at 3 T With a 32-Channel Head Coil: Technique and Clinical Applications

OBJECTIVE. The purpose of this article is to illustrate the utility of susceptibility-weighted imaging (SWI) as an adjunct to routine MRI of the brain in neurologic disorders. CONCLUSION. SWI is a 3D spoiled gradient-echo sequence that combines phase and magnitude information to provide a high sensitivity for the detection of blood degradation products, calcifications, and iron deposits.
