Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Group 1: First degree relatives of a family member with pulmonary fibrosis (n=8)
- Age greater than 40 years
- Have the ability to give written informed consent
- First degree relative of a family member with pulmonary fibrosis
- No known history of interstitial lung disease
- No tobacco use within the prior 6 months. Group 2: Subjects with interstitial lung abnormalities (ILAs) or interstitial lung disease (ILD) (n=22)
- Age greater than 40 years
- Have the ability to give written informed consent
- ILAs or early ILD (defined by presence of reticular markings and / or traction bronchiectasis but absence of a definite UIP pattern)
- No tobacco use within the prior 6 months.
Exclusion criteria
- Electrical implants such as cardiac pacemaker or perfusion pump
- Ferromagnetic implants such as aneurysm clips, surgical clips, prostheses, artificial hearts, valves with steel parts, metal fragments, shrapnel, metallic tattoos anywhere on the body, tattoos near the eye, or steel implants ferromagnetic objects such as jewelry or metal clips in clothing
- Historical eGFR of less than 30 mL/min/1.73 m2
- Pregnant or breastfeeding (a negative quantitative serum hCG pregnancy test is required for females having child-bearing potential before the subject can participate)
- Claustrophobic reactions
- Research-related radiation exposure exceeds current Radiology Department guidelines (i.e. 50 mSv in the prior 12 months)
- Unable to lie comfortably on a bed inside the MR-PET
- BMI \> 33 (limit of the PET-MRI table)
- Determined by the investigator(s) to be clinically unsuitable for the study (e.g. based on screening visit and/or during study procedures)
- Pneumonia or other acute respiratory illness within 6 weeks of study entry
- Parenchymal lung disease except for ILD/ILAs or emphysema
- Acute exacerbation of ILD within the prior 6 months
- VATS within the prior 6 months
- Prior radiation therapy to the thorax
- Known allergy to gadolinium.
Where
- Boston, Massachusetts
Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
