PURPOSE:After positive experience in interventional bronchoscopy in a feasibility study we investigated the usefulness in patients with respiratory symptoms in an general internal medical office.
METHODS:The VRI provides dynamic images of the lungs and quantitative data by recording vibrations during respiration from the chest wall, using 40 piezoelectric acoustic sensors and converts the signals to a dynamic grey scale image of the lung.
RESULTS:25 patients with respiratory symptoms (e.g. dyspnea, chronic cough, chest pain and haemoptyis)were investigated by the VRI.
CONCLUSION:The application was easy and could be performed during routine conditions by medical staff without complications. In several cases we could document the effect of antiobstructive treatment in asthma, pleural residuals after pneumonia and one case of central lung cancer that had escaped radiological exploration. In cases without clinical abnormalities also the VRI was normal.
CLINICAL IMPLICATIONS:VRI can be applied in a general internal practice as non-invasive, radiation free and readily repeatible technology in patients with respiratory symptoms and might become a screening tool for those patients for the practitioner.
