Hyperpolarized 129Xe MRI Lung Health Cohort
Hyperpolarized 129Xe MRI to Identify Structural Determinants of Low Lung Function and Respiratory Symptoms in Young Adults From the Lung Health Cohort
University of Kansas Medical Center
260 participants
Nov 30, 2023
OBSERVATIONAL
Conditions
Summary
A subset of young adults participating in the American Lung Association (ALA) Lung Health Cohort (LHC) will be imaged using Hyperpolarized 129Xe MRI to assess lung structure and function. Images will be used to improve the understanding of lung health and early lung abnormalities that may lead to chronic lung disease.
Eligibility
Inclusion Criteria2
- Is enrolled in the American Lung Association Lung Health Cohort Study.
- Has completed CT imaging for the LHC study within 2 years of the scheduled Xe-MRI date.
Exclusion Criteria3
- Pacemaker, internal defibrillator or other implanted electronic devices or any standard MRI contraindications (e.g., claustrophobia, > 140 cm shoulder circumference, dependent on weight distribution).
- Is pregnant or breastfeeding
- Oxygen saturation (SpO2) <88% on room air or with supplemental oxygen.
