The combination of the images and the health data could reveal interesting findings about the conditions of the body before diseases are diagnosed. Take dementia, for example. If some of the patients involved in the imaging study eventually develop the disease, the researchers can look back at the brain scans and other data collected before dementia set in. If they can figure out what those patients had in common, researchers might be able to see what might be causing the disease and potentially find new ways to treat it. The researchers plan to look at the brain scans for insights into other conditions like Alzheimer’s, depression, and stroke. Bone scans might shed light on osteoporosis and its relationship to other health conditions; detailed images of the heart might show signs of damage before a heart attack occurs. Other scans will look at the distribution of body fat compared to muscle in patient’s bodies which, combined with lifestyle and genetic markers for conditions like obesity, high cholesterol, and high blood pressure.
