GE Healthcare Announces FDA Clearance of GSI Xtream on Revolution CT


GE Healthcare has announced U.S. FDA 510(k) clearance of GSI Xtream on Revolution CT, complete with a series of clinical images and first installations at Duke University Medical Center (USA), Robarts Research Institute (Canada) and The First Affiliated Hospital of Dalian Medical University (China).

GSI Xtream on Revolution CT is the first volume spectral CT technology designed to improve small lesion detection, tissue characterization and metal artifact reduction, with a simplified workflow.

From setup to post processing, GSI Xtream is as intuitive as a single energy exam. GSI Assist and Clinical ID help standardize and automate protocol selection with images directly transferred to PACS and/or AW. These improvements, combined with native GSI reconstruction, deliver spectral CT workflow that’s twice as fast.
Spectral CT allows clinicians to go beyond anatomy visualization to tissue characterization, allowing for differentiation between similar HU densities such as cysts and enhancing lesions. With a contrast-to-noise ratio 60 percent higher at 120 kV than single energy CT, monochromatic images improve lesion detection and enhance contrast.

“Our design goal for the Revolution CT was to deliver outstanding clinical capabilities in spatial resolution, temporal resolution and wide coverage. With GSI Xtream, we’ve extended the platform with volume spectral CT that’s upgradable for all Revolution CT users,” says Scott Schubert, General Manager, Global Premium CT. GSI Xtream enhances Revolution CT’s platform with wide collimation and 50 cm FOV to deliver the only volume spectral CT. Enabled by ultrafast kV switching, clinicians can scan more challenging patients and reduce the effects of motion. The Gemstone Clarity detector combined with ASiR-VTM delivers dose neutral exams for patients of any size.
