The dataset was divided into a training cohort and a validation cohort in a 7:3 ratio. Additionally, patients from medical center 2 were collected for external test. A radiomics model was constructed using five machine learning algorithms: Logistic Regression (LR), Random Forest (RF), Quadratic Discriminant Analysis (QDA), YeoJohnson_LR, and YeoJohnson_LR (LDA). Receiver operating characteristic (ROC) and area under the curve (AUC) were used to evaluate the diagnostic efficacy of the five models, and the optimal prediction model was obtained. The optimal model was compared with three radiologists in the testing cohort.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 1,512 cases were included, including 1,407 cases from Center 1 (NTM-LD: 547; PTB: 860) and 105 patients from Center 2 (NTM-LD: 32; PTB: 73). Patients in the NTM-LD group were significantly older than those in the PTB group (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.001).

By comparing the five models, it was found that the YeoJohnson_LR (LDA) model was the best-performing prediction model, with an accuracy of 0.8286 in the external test. The AUCs of the YeoJohnson_LR (LDA) model on the training, validation, and test cohort were 0.8421, 0.8037, and 0.8233, respectively. In comparison with radiologists, the YeoJohnson_LR (LDA) model demonstrated gains of 3.12\u202f~\u202f15.62% in sensitivity and 6.85\u202f~\u202f12.33% in specificity.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The YeoJohnson_LR (LDA) model can be used to distinguish NTM-LD from PTB, assisting in rapid clinical diagnosis and benefiting patients with NTM-LD.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fmed.2026.1721949","type":"journal-article","created":{"date-parts":[[2026,1,21]],"date-time":"2026-01-21T06:45:05Z","timestamp":1768977905000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Distinguishing nontuberculous mycobacterial lung disease from pulmonary tuberculosis using radiomics machine learning models from CT images"],"prefix":"10.3389","volume":"13","author":[{"given":"Jiaofeng","family":"Zheng","sequence":"first","affiliation":[{"name":"Department of Radiology, Chongqing Public Health Medical Center","place":["Chongqing, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fang","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Research and Development, Shanghai United Imaging Intelligence","place":["Shanghai, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiangxin","family":"Zeng","sequence":"additional","affiliation":[{"name":"Department of Radiology, Chongqing Public Health Medical Center","place":["Chongqing, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weiqiang","family":"Shu","sequence":"additional","affiliation":[{"name":"Department of Radiology, Chongqing Public Health Medical Center","place":["Chongqing, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhiyang","family":"He","sequence":"additional","affiliation":[{"name":"Department of Radiology, Chongqing Public Health Medical Center","place":["Chongqing, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yurui","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Radiology, Chongqing Public Health Medical Center","place":["Chongqing, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yueqin","family":"Gao","sequence":"additional","affiliation":[{"name":"Department of Radiology, Public Health Clinical Center of Chengdu","place":["Chengdu, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shengxiu","family":"Lv","sequence":"additional","affiliation":[{"name":"Department of Radiology, Chongqing Public Health Medical Center","place":["Chongqing, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xueyan","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Radiology, Chongqing Public Health Medical Center","place":["Chongqing, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2026,1,21]]},"reference":[{"key":"ref1","volume-title":"World Health Organization.
