ORFAN is a study that looks at how different factors affect health using CT scans (a special kind of X-ray) and other health information. It aims to find new ways to predict and understand diseases, especially those affecting the heart and metabolism (how the body uses energy). The study involves collecting CT scans from both current and past patients, alongside their health information, to test new methods of analyzing these images. This helps doctors understand disease risks better and improves diagnosis. Participants will have their CT scans matched with blood tests, genetic info, and follow-up health data to track disease progression.

• Study includes people aged 18-99, but excludes those with active cancer or who can't/won't consent.
• Participation involves linking CT scans with health data, and there are no treatments given.
• No monetary compensation is mentioned, but you'll contribute to valuable medical research.
