Lung volume reduction surgery (LVRS) treats emphysema by removing severely emphysematous regions of the lung. Techniques that can better identify which regions of the lung to remove as well as assess the resultant changes in lung function could lead to better surgical outcomes. Here, we explored the feasibility of using hyperpolarized xenon-129 (HXe) MRI for this purpose. Xenon polarization Transfer Contrast (XTC) imaging was used to quantify gas exchange as a metric for assessing the severity and distribution of emphysematous lung regions before and after LVRS.
