To explore the value of machine learning-based magnetic resonance imaging (MRI) liver acceleration volume acquisition (LAVA) dynamic enhanced scanning for diagnosing hilar lesions. Methods. A total of 90 patients with hilar lesions and 130 patients without hilar lesions who underwent multiphase dynamic enhanced MRI LAVA were retrospectively selected as the study subjects. The 10-fold crossover method was used to establish the data set, 7\/10 (154 cases) data were used to establish the training set, and 3\/10 (66 cases) data were used to establish the validation set to verify the model. The region of interest was extracted from MRI images using radiomics, and the hilar lesion model was constructed based on a convolutional neural network. Results. There were significant differences in respiration and pulse frequency between patients with hilar lesions and without hilar lesions (P\u2009&lt;0.05). The subjective scores of the images in the first three phases of dynamic enhanced scanning in the training set were higher than those in the validation set (<jats:inline-formula>\n                     <a:math xmlns:a=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\">\n                        <a:mi>P<\/a:mi>\n                        <a:mo>&lt;<\/a:mo>\n                        <a:mn>0.05<\/a:mn>\n                     <\/a:math>\n                  <\/jats:inline-formula>). There was no significant difference between the training and validation set in the last three phases of dynamic enhanced scanning. Conclusion. Machine learn-based MRI LAVA dynamic enhanced scanning for diagnosing hilar lesions has high diagnostic efficiency and can be used as an auxiliary diagnostic method.<\/jats:p>","DOI":"10.1155\/2022\/9592970","type":"journal-article","created":{"date-parts":[[2022,2,25]],"date-time":"2022-02-25T02:35:20Z","timestamp":1645756520000},"page":"1-7","source":"Crossref","is-referenced-by-count":0,"title":["Machine Learning-Based MRI LAVA Dynamic Enhanced Scanning for the Diagnosis of Hilar Lesions"],"prefix":"10.1155","volume":"2022","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0213-1173","authenticated-orcid":true,"given":"Haijin","family":"Wang","sequence":"first","affiliation":[{"name":"School of Nursing, Anhui Medical University, Hefei, 230032, China"},{"name":"Department of Hepatobiliary and Pancreatic Surgery, The First Affiliated Hospital of Anhui Medical University, Hefei, 230022, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7294-9627","authenticated-orcid":true,"given":"Song","family":"Wang","sequence":"additional","affiliation":[{"name":"Medical imaging center, The Fourth Affiliated Hospital of Anhui Medical University, Hefei, 230002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6792-9901","authenticated-orcid":true,"given":"Lihua","family":"Zhou","sequence":"additional","affiliation":[{"name":"School of Nursing, Anhui Medical University, Hefei, 230032, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1002\/jmri.26239"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/bs.irn.2018.08.008"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1002\/jmri.25381"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1016\/j.urology.2018.08.044"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.2015151169"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1186\/s41747-018-0068-z"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1038\/nrclinonc.2017.141"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1007\/s11548-016-1467-3"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1109\/JBHI.2020.2967546"},{"key":"10","article-title":"Onlinear tribo-dynamic model and experimental verification of a spur gear drive under loss-of-lubrication condition","volume":"153, article 107509","author":"B.
