Functional and Structural Assessment of Endobronchial Valve Recipients Using Dynamic Hyperpolarized Xenon-129 MRI

Description

This study proposes to use hyperpolarized xenon-129 Magnetic Resonance Imaging (MRI) to study lung function of COPD patients who will receive endobronchial valve (EBV) therapy as part of their clinical standard-of-care. Once inhaled, HP xenon can provide information to imagers regarding functionality across specific regions of the lungs through the assessment of the replacement of air during the normal breathing cycle, how much oxygen is in the airspaces, and if the normal spongy tissue structure has been compromised by lung disease. Pre- (baseline) and post-EBV (follow-up) lung function imaging with HPXe will potentially lead to be better understand disease progression and treatment mechanism.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * COPD patients scheduled to receive endobronchial valve therapy
  • * Patient is conscious, cooperative and agrees to return for scheduled visits and tests
  • * 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 from the study.
