Our aim was to develop a lung graph-based machine learning model to identify f-ILD. A total of 417 HRCTs from 279 patients with confirmed ILD (156 f-ILD and 123 non-f-ILD) were included in this study. A lung graph-based machine learning model based on HRCT was developed for aiding clinician to diagnose f-ILD. In this approach, local radiomics features were extracted from an automatically generated geometric atlas of the lung and used to build a series of specific lung graph models. Encoding these lung graphs, a lung descriptor was gained and became as a characterization of global radiomics feature distribution to diagnose f-ILD. The Weighted Ensemble model showed the best predictive performance in cross-validation. The classification accuracy of the model was significantly higher than that of the three radiologists at both the CT sequence level and the patient level. At the patient level, the diagnostic accuracy of the model versus radiologists A, B, and C was 0.986 (95% CI 0.959 to 1.000), 0.918 (95% CI 0.849 to 0.973), 0.822 (95% CI 0.726 to 0.904), and 0.904 (95% CI 0.836 to 0.973), respectively. There was a statistically significant difference in AUC values between the model and 3 physicians (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). The lung graph-based machine learning model could identify f-ILD, and the diagnostic performance exceeded radiologists which could aid clinicians to assess ILD objectively.<\/jats:p>\n                <jats:p><jats:bold>Graphical Abstract<\/jats:bold><\/jats:p>\n                \n                <jats:p>Given a sequence of HRCT slices from a patient, the lung field is first automatically extracted. Next, this lung region is divided into 36 sub-regions using geometric rules, obtaining a lung atlas. And then, the lung graph is built based on 3D radiomics features of each sub-region of the lung atlas. Finally, the model\u2019s predictions were compared to the physicians\u2019 assessment results.<\/jats:p>","DOI":"10.1007\/s10278-023-00909-7","type":"journal-article","created":{"date-parts":[[2024,1,16]],"date-time":"2024-01-16T19:02:52Z","timestamp":1705431772000},"page":"268-279","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Developing the Lung Graph-Based Machine Learning Model for Identification of Fibrotic Interstitial Lung Diseases"],"prefix":"10.1007","volume":"37","author":[{"given":"Haishuang","family":"Sun","sequence":"first","affiliation":[]},{"given":"Min","family":"Liu","sequence":"additional","affiliation":[]},{"given":"Anqi","family":"Liu","sequence":"additional","affiliation":[]},{"given":"Mei","family":"Deng","sequence":"additional","affiliation":[]},{"given":"Xiaoyan","family":"Yang","sequence":"additional","affiliation":[]},{"given":"Han","family":"Kang","sequence":"additional","affiliation":[]},{"given":"Ling","family":"Zhao","sequence":"additional","affiliation":[]},{"given":"Yanhong","family":"Ren","sequence":"additional","affiliation":[]},{"given":"Bingbing","family":"Xie","sequence":"additional","affiliation":[]},{"given":"Rongguo","family":"Zhang","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0427-1460","authenticated-orcid":false,"given":"Huaping","family":"Dai","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2024,1,16]]},"reference":[{"issue":"6","key":"909_CR1","doi-asserted-by":"publisher","first-page":"733","DOI":"10.1164\/rccm.201308-1483ST","volume":"188","author":"WD Travis","year":"2013","unstructured":"Travis W D, Costabel U, Hansell D M, et al.
