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.
