New Technology Allows CT Scans to Be Done with a Fraction of the Conventional Radiation Dose

University of Michigan Health System is first U.S. academic site to put GE’s Veo into clinical use


A technological breakthrough is allowing the University of Michigan Health System to be the first teaching hospital in the U.S. to perform some CT scans using a fraction of the radiation dose required for a conventional CT image.
Over the past decade, U-M scientists have contributed to the research behind the new GE Healthcare technology, known as Veo.

“Reducing patients’ radiation exposure is a high priority for us,” says Ella Kazerooni, M.D., M.S., professor of radiology at the U-M Medical School. “The radiation dose for a standard chest CT is equal to about 70 chest x-rays. In comparison, a chest CT using Veo can use a radiation dose equivalent to just one or two chest x-rays."

Doses for scans using Veo, however, will vary depending on factors like the size of the patient, the part of the body being scanned, and the diagnostic task, Kazerooni notes.
