title: Susceptibility weighted imaging: data acquisition, image reconstruction and clinical applications.
abstract: Susceptibility-weighted imaging (SWI) is a novel method, that combines magnitude and phase information from a high-resolution, fully velocity compensated 3D T2-weighted gradient echo sequence. Phase images are unwrapped and high pass filtered to highlight phase changes associated with venous vessels and converted into a mask that is multiplied with the corresponding phase image. This technique has been applied thus far to the imaging of tumors, vascular malformations, trauma, stroke, micro-hemorrhages, and as a functional imaging method. The purpose of this paper is to present an overview of the current status of the technique and to illustrate its potential.
