Hyperpolarization shows emphysema in rat model
This hyperpolarized 83Kr MRI of excised rat lung shows a healthy control lung on the left and a lung that serves as a model of emphysema on the right. The dominance of the green color in the right image indicates a reduction in the lung's surface-to-volume ratio caused by alveolar degradation in this emphysema model.
