New scan could reveal hidden heart damage from cancer radiation
NCT ID NCT06373497
First seen Jun 25, 2026 · Last updated Aug 07, 2026 · Updated 3 times
Summary
This pilot study will test whether a special PET/MRI scan can detect real-time artery inflammation in the heart after chest radiation therapy. Ten adults with stage II-III or limited stage IV cancer who are at high risk for heart problems will be scanned before and 6 months after radiation. The goal is to see if this imaging method is feasible for spotting early signs of heart damage.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to better ways to monitor and predict heart damage from chest radiation in cancer patients.
- What could go wrong
- This is a very small, early-phase study with only 10 participants, so results may not apply to everyone. It is designed to test feasibility, not to prove a treatment works.

Inclusion Criteria * Age ≥ 18 years. * Have clinical stage II-III or oligo-metastatic stage IV malignancy (any histology) planned to be treated with thoracic radiotherapy (≥30 Gy) where the heart is in the treatment field. * Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0-2. * Planning to receive standard of care radiotherapy treatment. * Written informed consent obtained from subject and ability for subject to comply with the requirements of the study. * Ability to read, write, and understand English Exclusion Criteria * Estimated glomerular filtration rate (eGFR) \<45 mL/min/m2 or serum creatinine ≥1.5 mg/dL. * Patients with a known or previous allergy to iodinated contrast, gadolinium contrast, and/or 18F-NaF tracer. * Inability to receive PET tracer. * Inability to receive MRI, requiring sedation for MRI, or prohibitive implant and/or device, including ferromagnetic implants and ferromagnetic foreign bodies. * Subjects with claustrophobia, problems being in enclosed spaces, or inability to lie supine. * Subjects that are pregnant or breastfeeding. * Subjects unable to comply with visit instructions, including inability to lie still, hold breathe, or follow procedure instructions. * Allergy to animal dander or animal-instigated asthma. * Any other condition which, in the opinion of the investigator, may make the patient a poor candidate for participation in a clinical trial
