CT scans of the lungs of smokers with chronic obstructive pulmonary disease—when analyzed by a mathematical function called airway fractal dimension—can estimate increased risk of death for a group of people who are not otherwise identified as high-risk by conventional tests.

Even patients who have a family history of Alzheimer’s but have no symptoms show these […]
