August 15, 2019 — United Imaging announced that its uExplorer total-body positron emission tomography/computed tomography (PET/CT) system is now in use.
United Imaging developed uExplorer in partnership with the Explorer Consortium led by Simon Cherry, Ph.D., and Ramsey Badawi, Ph.D., from the University of California Davis. UC Davis Health has now completed installation of the uEexplorer and is actively using the technology for patient scans.
Part of United Imaging's all-digital PET/CT portfolio, uExplorer accomplishes total-body imaging in a single bed position in as little as 20 to 30 seconds. It also allows for fast and continuous tracking of tracer distribution in blood, organs and tissues throughout the body. With these capabilities, the uExplorer opens new research opportunities that have not been possible with traditional PET/CT technology. More specifically, the system offers support for pharmacokinetic studies and radiation dose evaluation.
"We're very proud that UC Davis Health is the site of the first uExplorer installation in North America," said Badawi, chief of nuclear medicine at UC Davis. "The images we're seeing with uExplorer are unprecedented. We're capturing detail we have never seen before, and I am sure this is going to positively affect patient care."
Added Cherry, professor of biomedical engineering and radiology, "We can now capture the dynamic distribution of our tracers at incredibly high temporal resolution, opening up new opportunities for innovative research using this powerful technology platform."
The first clinical patient in the U.S. to be scanned using the uExplorer was Magdalena Gonzalez, 49, a mother of seven who was scanned for the purpose of better staging her lymphoma.
