Distribution of Regional Lung Function, as Determined by the Vibration Response Image Generated by the VRI-2000 System as Compared With Standard Radio-nuclear Method
In Brief
An observational study evaluating Observational study - no intervention for Emphysema and COPD. Completed, enrolled 25 participants across 1 site.
Detailed Summary
Assessment of regional contribution of different areas of the lung to its integrated function is often required, such as prior to lung resection in the presence of tumor or emphysema. This assessment is derived from the proportion of zonal radionuclear perfusion or ventilation. The investigators hypothesized that lung VRI may provide an alternative approach to assess regional lung function.
