RECRUITING

Quantitation and Spatial Registration of Airways Dysfunction With Dynamic 19F MRI in Cystic Fibrosis

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

The purpose of this study is to look at lung ventilation in people with cystic fibrosis over time (1 year) using magnetic resonance imaging (MRI) with an inhaled contrast gas, and compare these measures to lung function assessed by spirometry and multiple breath nitrogen washout. This study also looks at how these measures change in response to a pulmonary exacerbation and treatment (if applicable). Over the span of a year, participants would be asked to complete 3-5 visits to the University of North Carolina at Chapel Hill (UNC). with each lasting up to 4 hours. If participants do not have a pulmonary exacerbation during the year they would be asked to complete 3 visits (one at enrollment, a second roughly 2 weeks later, and the third approximately a year later). If participants do experience a CF pulmonary exacerbation they would complete 5 visits (Visit 1, Visit 2, two exacerbation visits with one before treatment and the other after, and Visit 3 at one year after Visit 1). Only one exacerbation per participant will be tracked. Participants are eligible for this study if they are 18 years old or older, have Cystic Fibrosis (CF) with mild lung disease (FEV1 \>/= 60%), and can undergo an MRI. There are no known benefits for participating in this study.

  1. 1. Active or past smokers or vapers with less than 1 year since quitting or \>10 pack-year smoking history
  2. 2. Unable to undergo a 3.0-Tesla MRI exam of the lungs and chest because of contraindications including
  3. 1. Occupation (past or present) of machinist, welder, or grinder;
  4. 2. Injury to the eye involving a metallic object
  5. 3. Injury to the body by a metallic object (bullet, bullet ball, shrapnel)
  6. 4. Presence of a cardiac pacemaker or defibrillator
  7. 5. Presence of aneurysm clips
  8. 6. Presence of carotid artery vascular clamp
  9. 7. Presence of neurostimulator
  10. 8. Presence of insulin or infusion pump
  11. 9. Presence of implanted drug infusion device that is not known to be MRI compatible (i.e., was placed outside of UNC or is older than 10 years)
  12. 10. Bone growth or fusion simulator
  13. 11. Presence of cochlear, otologic or ear implant
  14. 12. Any type of prosthesis (eye, penile, etc.)
  15. 13. Artificial limb or joint
  16. 14. Non-removable electrodes (on body, head or brain)

  20. 18. Any implant held in place by a magnet
  21. 19. Transdermal delivery system (e.g. Nitro)
  22. 20. An intrauterine device or diaphragm that is not MRI compatible
  23. 21. Tattooed makeup (eyeliner, lips, etc.) or tattoos covering \>25% of body surface area
  24. 22. Body piercings (must be removed before MRI)
  25. 23. Any metal fragments

  28. 26. Hearing aid (remove before MRI) aa. Dentures (remove before MRI) bb. Claustrophobia
  29. 3. Unable to tolerate inhalation of gas mixture
  30. 4. Presence of facial hair that may interfere with the fit of the mask (and unwillingness to shave prior to each MRI)
  31. 5. Any changes in medications that may affect CF lung disease in the past 28 days, including any experimental therapies
  32. 6. Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with trial participation or may interfere with the interpretation of trial results and, in the judgment of the investigator, would make the subject inappropriate for entry into this trial.
  33. 7. Pregnancy; women of childbearing potential must have a confirmed negative urine pregnancy test on the day of the MR scan, prior to the MRI scan.
