Quantification of Pulmonary Ventilation using Hyperpolarized 3He Magnetic Resonance Imaging
… derived from these images, specifically the ventilation defect volume (VDV) and ventilation defect percent (VDP) have the potential to provide new sensitive measures of lung function. Here, we evaluate the reproducibility of VDV, and explore the sensitivity of these measurements in healthy …

Eosinophilic Asthma Response to Therapy: 129Xe Magnetic Resonance Imaging and Computed Tomography
… the in vivo visualization and quantification of ventilation abnormalities, which are thought to reflect airway abnormalities such as airway inflammation and mucus plugging. Therefore, CT and MRI are poised to non-invasively evaluate the pulmonary structural and functional changes in eosinophilic …

Improved Visualization and Quantification for Hyperpolarized 129Xe MRI
… of the lung. Nuclear medicine, employing 133Xe ventilation and 99Tcm-macroaggregated albumin perfusion scan (ventilation/perfusion V/Q scan) can assess the inequality of airflow and blood flow in the lung. However, this V/Q scan evolves the usage of radioactive tracers and is limited by both …
