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
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.
Observational
Observational Model: Cohort, Time Perspective: Prospective
Comparison of regional lung vibration energy with regional lung function
To map regional lung vibration energy in patients with emphysema by using the lung image generated by the VRI system and compare findings to distibution of perfusion and ventilation in standard V/Q scans
