PET/CT Imaging to Evaluate Cardiac Radiation Damage in Patients With Lung or Esophageal Cancer, EUCLID Trial

This clinical trial examines positron emission tomography (PET)/computed tomography (CT) in evaluating cardiac radiation damage in patients with lung or esophageal cancer. As part of the treatment for lung or esophageal cancer, patients will undergo radiation therapy. Sometimes, during this treatment, the heart is also subjected to some radiation which could affect its function, either increasing or decreasing the function. It is not known the consequences of this change nor is it known if doctors can detect the changes associated with the radiation. Sarcoidosis FDG positron emission tomography (PET)-computed tomography (CT) scans are a common way to image cardiac inflammation and myocardial viability. This study may help doctors image the heart before, during and after radiotherapy to monitor any changes.
