Susceptibility-weighted Imaging: Technical Essentials and Clinical Neurologic Applications
Radiology. 2021 Feb 23:203071. doi: 10.1148/radiol.2021203071. Online ahead of print.ABSTRACTSusceptibility-weighted imaging (SWI) evolved from simple two-dimensional T2*-weighted sequences to three-dimensional sequences with improved spatial resolution and enhanced susceptibility contrast. SWI is an MRI sequence sensitive to compounds that distort the local magnetic field (eg, calcium and iron), in which the phase information can differentiate. But the term SWI is colloquially ... read more
