- W3028682335 abstract "Objective To discuss the value of vibration response imagine (VRI) on evaluating the pulmonary function of interstitial lung disease (ILD).Methods 80 patients who were diagnosed as ILD from June 2010 to September 2011 enrolled in this study.Then,all the patients took the VRIxp pulmonary function test so as to make a comparison with the traditional pulmonary function test.This paper analyzed the advantage and disadvantage of VRIxp and the traditional pulmonary function teat in evaluating the pulmonary function of ILD by observing the changes of patients' condition after the test respectively.Results The changes and significance of the main VRIxp parameters:①By observing airflow distribution map and maximum vibration energy diagram,a variety of abnormities were discovered such as the out-sync of the images and the size difference in all patients.②It is found that 69 patients had abnormal energy distribution.According to grouping of the various disease types and CT scan,the energy values were compared which indicated that the abnormities had no statistical significance.③ The energy curve had some abnormities such as the platform and curve separation.④The study showed that VRIxp could qualitatively,quantificationally detect the abnormal breath sounds and VRIxp was more sensitive than that of traditional auscultation (the positive rate were 90.00% vs 82.50%,respectively).⑤VRIxp could locate the lesion directly by combining air distribution figure with regional energy distribution.The accuracy rate was as high as 91.25% compared with CT scan.Comparing with traditional pulmonary function technology,there were some advantages of VRI.①For some patients,their ventilatory functions were detected as normal by traditional pulmonary function technology,while through VRI test,the results were abnormal.And the lesions were consistent with HRCT.② By evaluating conditions of patients before and after pulmonary function test,VRIxp was less secondary effects than traditional pulmonary function technology (the positive rate were 0.32 vs 6.59,respectively).Conclusions VRIxp,as a new method,can test the pulmonary function of subjects in normal breathing state.VRIxp has many advantages over traditional pulmonary function technology,such as displaying the volume change of lung in a dynamic,direct,fast,and accurate way.It also can detect the lesion and the abnormal breath sounds more sensitively.More importantly,it has no side effect on the patients' condition.It is especially suitable for the patients of ILD who have serious dyspnea.Key words: Vibration Response Imaging; Interstitial lung disease; Pulmonary function test" @default.
