Designed for excellent visualization of vasculature and blood products.


SWAN helps clearly delineate small blood vessels, microbleeds, and large vascular structures in the brain. SWAN is also designed to visualize iron and calcium deposits. SWAN is also designed to visualize iron and calcium deposits by providing both phase and magnitude images to aid in an easier diagnosis.

SWAN applies a multi-TE readout technique that generates more than double signal-to-noise ratio and is inherently less affected by the chemical shift compared to conventional SWI techniques. The end result is a clear, high resolution 3D dataset that integrates a broad range of distinct tissue contrasts with significantly enhanced susceptibility information, and signal-to-noise ratio. Typical whole brain acquisition with 3D, sub-millimeter resolution takes about four minutes, and image reconstruction is virtually instantaneous.

"SWAN consistently generates very conspicuous images of microbleeds, with dramatic contrast. In the past the referring physicians at times questioned radiologist's diagnosis, now with SWAN they can see them across the room!"
