Vibration Response Imaging (VRI) in Management and Evaluation in Patients With Pleural Effusion

Completed

Conditions studied: Pleural Effusion

In brief

The primary purpose of this study is evaluate the VRI device's accuracy in diagnosis of pleural effusion (in comparison to chest x-ray and ultrasonography), and to assess the pleural effusion location and size. The VRI system uses pressure sensors (electronic stethoscopes) to record the energy created by the airflow in the lungs during breathing.
