Study Summary

This study proposes to use hyperpolarized xenon-129 Magnetic Resonance Imaging (MRI) to study lung function of COPD patients who will receive endobronchial valve (EBV) therapy as part of their clinical standard-of-care. Once inhaled, HP xenon can provide information to imagers regarding functionality across specific regions of the lungs through the assessment of the replacement of air during the normal breathing cycle, how much oxygen is in the airspaces, and if the normal spongy tissue structure has been compromised by lung disease. Pre- (baseline) and post-EBV (follow-up) lung function imaging with HPXe will potentially lead to be better understand disease progression and treatment mechanism.

Primary Outcome

Endobronchial valve receiving patients will have HPXe MRI sessions for assessing lung function parameters as measured from inhaled hyperpolarized xenon distribution inside the lungs. Fractional ventilation will be obtained based on the signal build up for dynamic breathing of HP 129Xe and room air. TV and FRC will be determined based on the signal build up at inhalation and the gas remaining in the lung at exhalation. τ will be determined by the signal intensity reaching other parts of the lung
