Distribution of Regional Lung Function by Vibration Response Imaging

Status Completed

Clinical Trial 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.

Clinical Trial Description

Patients diagnosed with moderate-to-severe COPD by lung function studies and clinical evaluation presented in stable clinical condition and were evaluated by lung sound recordings and quantitative V/Q lung scintigraphy. Regional signals (percentage of lung sounds) for left and right lungs were compared with the corresponding regional count percentages of each radionuclide scan, by V/Q scan regions of interest. ;
