Abstract Objective To compare the sensitivity of lung ultrasound (LUS) with high-resolution computed tomography (HRCT) in the diagnosis of interstitial lung disease (ILD). Methods A retrospective analysis of 30 patients with clinically diagnosed ILD who were hospitalized in Binzhou Medical University Hospital from June 2018 to June 2019. All patients underwent bilateral LUS examination and chest high-resolution CT (HRCT) scan with informed consent. The interval between inspection and HRCT is no more than 24 hours.Record the pleural and lung parenchymal sonograms, observe the number of B lines, the thickness of the pleural line, whether the pleural line is regular, whether there is a hypoechoic area under the pleura, and whether there is fluid in the chest. The sensitivity of LUS and HRCT in the diagnosis of ILD was calculated by clinical diagnosis as the gold standard. Results Of the 30 patients with ILD, 4 patients (13.3%) had false negative for LUS and 3 (10%) had false negative for HRCT. No false positive cases were found. All patients were ILD, so the specificity of the examination could not be counted. With the clinical diagnosis of ILD as the gold standard, the sensitivity of LUS and HRCT for the diagnosis of ILD was 0.87 (0.69-0.96) and 0.90 (0.73-0.98), respectively. There was no significant difference in sensitivity between the two groups (P=1.00). Conclusion LUS is not inferior to HRCT in the diagnosis of ILD. Considering its safety, low cost, portability and practicability, LUS can be used as a potential imaging tool to replace HRCT screening ILD.
