Lung Functional Avoidance Radiotherapy Using Hyperpolarized Xenon MRI

Starting soon · Phase 1/Phase 2

Conditions studied: Carcinoma, Non-Small-Cell Lung

In brief

Cancer radiation treatment plans that employ lung functional avoidance methods require 3D maps that differentiate regions of healthy lung function from regions of functional compromised tissue to deliver sufficient dose to the tumor while preserving as much functioning lung as possible. Hyperpolarized xenon-129 MRI can provide maps of ventilatory function and gas exchange to the bloodstream. Improving treatment plans based on this novel imaging modality could reduce risk or severity of radiation pneumonitis and improve post-treatment quality of life.

Who can join

Age: 18 and older, up to 85. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Patients over 18 years with a diagnosis of non-small lung cancer and planned for a definitive course of radiation therapy.
• Preferred patients will have had successful radiation therapy for a prior lung cancer and developed a secondary lung cancer for which are to be treated.
• Other de-nuovo lung cancer patients planned for radiation therapy with lung heterogeneity from natural co-morbidities (e.g., COPD stage 3+).

You may not qualify if…

• Patients less than 18 years old
• Patients known to be pregnant - a positive pregnancy test will be used to respectively exclude pregnant patients,
• Any known contraindication to MRI examination
• Anyone with an implanted metal device
• Inability to provide informed consent
• A language, communication, cognitive or behavioral impairment that might interfere with fully informed participation in the study.
• History of uncompensated organ failure (i.e. organ failure that is not stabilized through medical intervention), which will be assessed by the PI.
• Homelessness or other unstable living situation
• Active drug or alcohol dependence
• Claustrophobia
• Subjects weighting more than 300 pounds.
• Subjects with chest size larger than the bore of MRI machine can accommodate
