With the goal of minimizing risk while preserving personal protective equipment, radiologists at the University of Utah are implementing a new technique for taking x-rays of patients, according to ABC News 4 in Salt Lake City.

Technicians are using portable x-ray machines to take chest x-rays through the glass of observation rooms with suspected or confirmed COVID-19 patients inside. Limiting interaction between radiologist and patient means medical personnel don’t have to suit up in personal protective equipment.

“We are making sure it is the same as when we are imaging patients while inside the room,” says [Phuong-Anh Thi] Duong, MD, with the University of Utah.

Dr. Duong says this new practice saves nurses and x-ray radiologist from changing into one to two new PPE sets.
