Summary

This trial aims to study how 3 biomarkers change when people respond to treatments. It's funded by the US National Institutes of Health.

Who is the study for?
This trial is for adults over 18 with interstitial lung disease, thromboembolic pulmonary hypertension, or who are healthy volunteers. Participants must be able to give consent and follow the study plan. Smokers or those with recent respiratory illness, certain heart conditions, low oxygen levels, MRI contraindications, inability to hold breath for 10 seconds, pregnancy or lactation are excluded.
What is being tested?
The study tests how three biomarkers from a special type of MRI using hyperpolarized Xenon gas (129Xe) change in response to interventions like oxygen administration. It aims to improve understanding of various lung diseases and their treatment.
What are the potential side effects?
While not explicitly listed in the provided information, potential side effects may include discomfort from wearing the MRI vest coil and holding one's breath during imaging. Oxygen administration can sometimes cause dryness of nasal passages or mild headache.

Trial Design

3Treatment groups
Active Control
Group I: Transfusion and Phlebotomy PatientsActive Control1 Intervention
Individuals receiving treatment for their blood hemoglobin levels or are a healthy volunteer who is planning to donate blood.
Group II: Oxygen Administration PatientsActive Control2 Interventions
Individuals diagnosed with a chronic blood clot in their lungs and are planning on having surgery to remove it (CTEPH), or have an interstitial lung disease (ILD), or have dyspnea, or are a healthy volunteer.
Group III: Acute or Chronic Pulmonary Embolism PatientsActive Control1 Intervention
Individuals recently diagnosed with a blood clot in their lungs.
