Abstract Objective: To discuss the relationship between pulmonary ultrasound score and function of lung in patients with interstitial lung disease(ILD). Methods: Forty-three patients with ILD who had complete clinical data underwent HRCT, pulmonary ultrasound and lung function within a week. They were graded by pulmonary ultrasound according to the lung sonography image characteristics(pleural thickness, pleural surface, subpleural nodules, B lines in a section that shows the maximum number). The correlation analysis of pulmonary ultrasound score, index of lung function(FEV1, FVC, TLC, RV, DLCO, DLCO/VA) and chest HRCT image was performed. Results: A negative correlation was found between total score of lung ultrasound, pleural score, B line score and some index of lung function(FVC, FEV1, DLCO, DLCO/VA), and there was the most significant relationship between DLCO and total score of lung ultrasound(r=-0.570, P<0.000), pleural score(r=-0.563, P<0.000), B line score(r=-0.594, P<0.000). The difference between early and late images of ultrasound score in HRCT interstitial lung disease was statistically significant(P<0.05). Conclusion: A negative correlation is found between lung ultrasound score and the main indicators of lung function. The difference between early and late images of ultrasound score in HRCT interstitial lung disease is statistically significant(P<0.05). Pulmonary ultrasound score can reflect the severity of lung to some extent.
