The Parkinson's Progression Markers Initiative (PPMI) served as the training set, with control group and PD patients (HC: 102 and PD: 102) from 24 global sites. Our institution's data was utilized as the test set (HC: 91 and PD: 79). Machine learning was employed to establish multiple models for PD diagnosis based on texture features of the cerebellum's gray and white matter. Results underwent evaluation through 5-fold cross-validation analysis, calculating the area under the receiver operating characteristic curve (AUC) for each model. The performance of each model was compared using the Delong test, and the interpretability of the optimized model was further augmented by employing Shapley additive explanations (SHAP).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The AUCs for all pipelines in the validation dataset were compared using FeAture Explorer (FAE) software. Among the models established by Kruskal-Wallis (KW) and logistic regression via Lasso (LRLasso), the AUC was highest using the \u201cone-standard error\u201d rule. 'WM_original_glrlm_GrayLevelNonUniformity' was considered the most stable and predictive feature.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The texture features of cerebellar gray matter and white matter combined with machine learning may have potential value in the diagnosis of Parkinson's disease, in which the heterogeneity of white matter may be a more valuable imaging marker.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fnagi.2024.1393841","type":"journal-article","created":{"date-parts":[[2024,6,11]],"date-time":"2024-06-11T18:08:49Z","timestamp":1718129329000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":12,"title":["A more objective PD diagnostic model: integrating texture feature markers of cerebellar gray matter and white matter through machine learning"],"prefix":"10.3389","volume":"16","author":[{"given":"Yini","family":"Chen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yiwei","family":"Qi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tianbai","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andong","family":"Lin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Ni","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Renwang","family":"Pu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bo","family":"Sun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,6,7]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"45347","DOI":"10.1038\/srep45347","article-title":"Discriminating cognitive status in Parkinson's disease through functional connectomics and machine learning","volume":"7","author":"Ab\u00f3s","year":"2017","journal-title":"Sci.
