To evaluate the role of radiomics based on magnetic resonance imaging (MRI) in the biological activity of hepatic alveolar echinococcosis (HAE). <jats:italic>Methods<\/jats:italic>. In this study, 90 active and 46 inactive cases of HAE patients were analyzed retrospectively. All the subjects underwent MRI and positron emission tomography computed tomography (PET\u2010CT) before surgery. A total of 1409 three\u2010dimensional radiomics features were extracted from the T2\u2010weighted MR images (T2WI). The inactive group in the training cohort was balanced via the synthetic minority oversampling technique (SMOTE) method. The least absolute shrinkage and selection operator (LASSO) regression method was used for feature selection. The machine learning (ML) classifiers were logistic regression (LR), multilayer perceptron (MLP), and support vector machine (SVM). We used a fivefold cross\u2010validation strategy in the training cohorts. The classification performance of the radiomics signature was evaluated using receiver operating characteristic curve (ROC) analysis in the training and test cohorts. <jats:italic>Results<\/jats:italic>. The radiomics features were significantly associated with the biological activity, and 10 features were selected to construct the radiomics model. The best performance of the radiomics model for the biological activity prediction was obtained by MLP (AUC = 0.830 \u00b1 0.053; accuracy = 0.817; sensitivity = 0.822; specificity = 0.811). <jats:italic>Conclusions<\/jats:italic>. We developed and validated a radiomics model as an adjunct tool to predict the HAE biological activity by combining T2WI images, which achieved results nearly equal to the PET\u2010CT findings.<\/jats:p>","DOI":"10.1155\/2021\/6681092","type":"journal-article","created":{"date-parts":[[2021,4,9]],"date-time":"2021-04-09T21:21:37Z","timestamp":1618003297000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Hepatic Alveolar Echinococcosis: Predictive Biological Activity Based on Radiomics of MRI"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8787-6405","authenticated-orcid":false,"given":"Bo","family":"Ren","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhoulin","family":"Miao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuwei","family":"Xia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5021-0968","authenticated-orcid":false,"given":"Wenya","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tieliang","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aierken","family":"Aikebaier","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,4,9]]},"reference":[{"key":"e_1_2_13_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(03)14573-4"},{"key":"e_1_2_13_2_2","doi-asserted-by":"publisher","DOI":"10.5152\/dir.2015.15456"},{"key":"e_1_2_13_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.actatropica.2009.11.001"},{"key":"e_1_2_13_4_2","doi-asserted-by":"publisher","DOI":"10.1051\/parasite\/2014073"},{"key":"e_1_2_13_5_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00436-019-06416-5"},{"key":"e_1_2_13_6_2","doi-asserted-by":"publisher","DOI":"10.1051\/parasite\/2014072"},{"key":"e_1_2_13_7_2","first-page":"2824","article-title":"Alveolar echinococcosis: correlation of imaging type with PNM stage and diameter of lesions","volume":"124","author":"Wang J.","year":"2011","journal-title":"Chinese Medical Journal"},{"key":"e_1_2_13_8_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0149440"},{"key":"e_1_2_13_9_2","doi-asserted-by":"publisher","DOI":"10.12659\/MSM.903929"},{"key":"e_1_2_13_10_2","doi-asserted-by":"publisher","DOI":"10.2967\/jnumed.112.109942"},{"key":"e_1_2_13_11_2","doi-asserted-by":"publisher","DOI":"10.1038\/srep11075"},{"key":"e_1_2_13_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejca.2011.11.036"},{"key":"e_1_2_13_13_2","doi-asserted-by":"publisher","DOI":"10.1002\/cam4.3185"},{"key":"e_1_2_13_14_2","doi-asserted-by":"publisher","DOI":"10.1093\/cvr\/cvaa021"},{"key":"e_1_2_13_15_2","doi-asserted-by":"publisher","DOI":"10.21037\/jtd.2019.05.32"},{"key":"e_1_2_13_16_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00330-019-06427-x"},{"key":"e_1_2_13_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.acra.2018.09.025"},{"key":"e_1_2_13_18_2","doi-asserted-by":"publisher","DOI":"10.1002\/jmri.26224"},{"key":"e_1_2_13_19_2","doi-asserted-by":"crossref","unstructured":"ZwanenburgA.
