‘Dem Bones’

David Yawitz, executive officer of the Community Outreach Program of the Division of Geriatrics and Nutritional Science, explains results of a peripheral dual energy X-ray absorptiometry (pDEXA) screening that measures Pauline Vivater’s bone density. The X-ray equipment is connected to a laptop computer, which shows a color-coded image of the person’s forearm showing areas of high and low bone density. The screening took place at the Brentmoor retirement community in University City.
