Showing patients their medical images might encourage them to take a more proactive approach to their health, according to new research published in PLOS Medicine. 

The meta-analysis of more than 9,000 participants revealed that when patients who undergo medical imaging are shown their results alongside a personalized review of their own disease risk, they are more likely to reduce risky behaviors, including following a healthier diet and routinely exercising. 

“There is ongoing clinical and research interest in determining whether providing personalized risk information could motivate risk-reducing health behaviors,” corresponding author Garreth J. Hollands, with the behavior and health research unit at the University of Cambridge, and colleagues explained. “One such intervention involves feeding back images generated via medical imaging technologies that assess an individual’s current disease status or risk.” 

The meta-analysis included controlled trials of adults who had undergone medical imaging procedures to assess health status and disease risk, for which personal risk may be reduced by changing their lifestyles. Monitored behaviors included smoking, medication use, physical activity, diet, oral hygiene habits, sun protection, tanning booth use, blood glucose testing, skin self-examination and foot care.
