This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This research study is testing whether a special type of heart imaging called PET-CT can detect early signs of heart damage from radiation therapy used to treat lung or esophageal cancer. Researchers want to understand if these imaging changes can help predict which patients might develop heart problems or have better or worse survival outcomes. If successful, this imaging could help doctors design safer radiation treatment plans in the future.
Radiation therapy is an important treatment for lung and esophageal cancer, but it can sometimes damage the heart. Right now, doctors don't have a good way to detect this damage early or predict which patients will be affected. This study aims to fill that gap by testing whether advanced imaging can spot these changes before they cause serious problems.

You will have heart imaging scans at three time points: before your radiation therapy starts, sometime during your treatment, and after your radiation is complete. Each scan involves lying still in an imaging machine for a short period. After your treatment ends, you'll have follow-up appointments at 12 months and 24 months to see how your heart is doing. The entire study lasts about 2 years.
