  • "Hyper polarized Xenon-129 MRI will be directly compared to a radioactive Xe-133 scintigraphy to detect defects in lung ventilation from airflow limitation."
  • "Hyperpolarized Xenon-129 MRI has been developed by a number of techniques for imaging the lung that provide information about various aspects of lung function and structure."
  • "We will directly compare human ventilation lung images in subjects with COPD, using nuclear medicine ventilation imaging with Xenon-133 gas scintigraphy versus hyperpolarized xenon-129 gas MRI."

Not stated
  • Study-related exams and procedures are typically provided at no cost. This is how many trials work in general — confirm the details for this study with the study team.
  • Participants are monitored closely by the research team throughout the study.
  • Some participants may receive access to an investigational treatment, which is still being studied.
  • Your participation helps researchers learn whether this approach could help future patients.

About this study

Hyper polarized Xenon-129 MRI will be directly compared to a radioactive Xe-133 scintigraphy to detect defects in lung ventilation from airflow limitation. This study is conducted as a pilot study with intention to conduct a larger clinical trial.

Compensation is read from the study's own description and may be missing — always confirm with the study team.
