GE Healthcare announced today the FDA clearance of GSI Xtream on Revolution CT, the first volume spectral CT technology designed for better visualization and simplified workflow.

The new technology improves the detection of small lesions and can differentiate between tissue with similar densities better than conventional CT systems, while reducing metal artifacts and playing friendly with image-viewing software.

“The workflow has been designed to be similar to a single energy acquisition with faster image reconstruction, clinical identifiers and direct transfer to PACS,” Sonia Sahney, premium CT global product marketing manager, told HCB News.
With metal artifact reduction, GSI (Gemstone spectral imaging) Xtream also maintains spatial resolution so that clinicians are able to properly image patients with metal implants.



Built into the spectral imaging solution are GSI Assist and Clinical ID, smart technologies designed to help physicians simplify their workflow, inform decision-making on dose neutrality and quickly generate image reconstructions.

The field of view of GSI Xtream is 50 centimeters and allows for fast kV switching, so patients can be scanned in a more efficient manner while reducing the effects of their movement during imaging.

It has a contrast-to-noise ratio that is 60 percent higher than single energy CT at 120 kV.

Units of the GSI Xtream on Revolution CT have already been installed at Duke University Medical Center, Robarts Research Institute, and The First Affiliated Hospital of Dalian Medical University.

“Spectral CT/dual energy CT has always been seen as a research application because of the advanced nature of-post processing and interpretation,” said Sahney. “GSI Xtream on Revolution CT introduces intuitive workflow so it can be used routinely on angiography exams, patients with metal implants, oncology patients, gout assessment, and more.”
