Smart scans aim to spare healthy lungs during cancer treatment
NCT ID NCT06925295
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether special MRI scans with xenon gas can show which parts of the lung work best. Doctors then aim to aim radiation away from those healthy areas during lung cancer treatment. The goal is to learn if this approach reduces lung damage and helps breathing. About 15 adults with lung cancer who are scheduled for radiation therapy will take part.

Willing and able to provide informed consent and adhere to visit/protocol schedules (Consent must be given before any study procedures are performed.) 3. Clinical diagnosis of lung cancer made by a board-certified oncologist with intent to treat with stereotactic body radiation therapy. We will not exclude individuals based on cancer type or severity of disease with the exception of the below criteria Exclusion Criteria: Subjects presenting with any of the following will not be included in the trial: 1. Subject is less than 18 years old or incarcerated 2. MRI is contraindicated based on responses to MRI screening questionnaire 3. Subject is pregnant or lactating 4. Resting oxygen saturation \<90% on supplemental oxygen 5. Respiratory illness of bacterial or viral etiology within 30 days of planned treatment 6. Subject has history of any known ventricular cardiac arrhythmia 7. Subject has history of cardiac arrest within the last year 8. Subject has prior history of cancer treatment with radiation therapy to the lung 9. Subject has concurrent cancer treatment with agents associated with increased risk of radiation pneumonitis (e.g. immunotherapy, chemotherapy) 10. Subject does not fit into 129Xe vest coil used for MRI 11. Subject cannot hold his/her breath for 15 seconds 12. Subject deemed unlikely to be able to comply with instructions during imaging 13. Medical or psychological conditions which, in the opinion of the investigator, might create undue risk to the subject or interfere with the subject's ability to comply with the protocol requirements
