U.S. Air Force Lt. Col. (Dr.) David Gover and Maj. (Dr.) Jason Hoskins, 60th Medical Group interventional radiologists at David Grant U.S. Air Force Medical Center conduct an Yttrium-90 radioembolization procedure on a patient with liver cancer, Sept. 7, 2018, Travis Air Force Base, Calif. The Y-90 radioembolization is an advanced and minimally invasive method utilized for this disease by delivering millions of tiny radioactive beads inside the blood vessels that feed a tumor. The high dose of targeted radiation prospectively kills the tumor while sparing normal tissue. This was the first time the treatment was performed at DGMC.
