【摘要】Background Although chest radiography is a useful examination tool,it has limitations.Because not all chest conditions can be detected on a radiograph,radiography cannot necessarily rule out all irregularities in the chest.Therefore,further imaging studies may be required to clarify the results of a chest radiograph,or to identify abnormalities that are not readily visible.The aim of this study was to compare traditional chest radiography with acoustic-based imaging (vibration response imaging) for the detection of lung abnormalities in patients with acute dyspnea.Methods The current investigation was a pilot study.Respiratory sounds throughout the respiratory cycle were captured using an acoustic-based imaging technique.Consecutive patients who presented to the emergency department with acute dyspnea and a normal chest radiograph on admission were enrolled and underwent imaging at the time of presentation.Dynamic and static images of vibration (breath sounds) and a dynamic image score were generated,and assessments were made using an evaluation form.Results In healthy volunteer controls (n=61),the mean dynamic image score was
