One dataset included 77 normal samples, and the other included 154 samples (77 normal and 77 abnormal). A total of 20 samples that contained normal and abnormal cochleae in three CT types (GE 64, GE 256, and SE-DS) were tested on the three models. The Dice similarity coefficient (DSC) and Hausdorff distance (HD) were used to assess the models.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The segmentation performances of the three models improved after adding abnormal cochlear images for training. SegResNet achieved the best performance. The average DSC on the test set was 0.94, and the HD was 0.16\u2005mm; the performance was higher than those obtained by the 3D U-Net and UNETR models. The DSCs obtained using the GE 256 CT, SE-DS CT, and GE 64 CT models were 0.95, 0.94, and 0.93, respectively, and the HDs were 0.15, 0.18, and 0.12\u2005mm, respectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The SegResNet model is feasible and accurate for automated cochlear segmentation of temporal bone CT images.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/02841851241307333","type":"journal-article","created":{"date-parts":[[2025,1,22]],"date-time":"2025-01-22T06:21:31Z","timestamp":1737526891000},"page":"305-311","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Utilizing deep learning for automatic segmentation of the cochleae in temporal bone computed tomography"],"prefix":"10.1177","volume":"66","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3230-9208","authenticated-orcid":false,"given":"Zhenhua","family":"Li","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology-Head and Neck Surgery, Hunan Provincial People's Hospital, The First Affiliated Hospital of Hunan Normal University, Changsha, Hunan, PR China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Langtao","family":"Zhou","sequence":"additional","affiliation":[{"name":"School of Computer Science and Cyber Engineering, Guangzhou University, Guangzhou, PR China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Songhua","family":"Tan","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Head and Neck Surgery, The First Affiliated Hospital of Guangxi Medical University, Nanning, Guangxi, PR China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bin","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology-Head and Neck Surgery, Hunan Provincial People's Hospital, The First Affiliated Hospital of Hunan Normal University, Changsha, Hunan, PR China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Xiao","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology-Head and Neck Surgery, Hunan Provincial People's Hospital, The First Affiliated Hospital of Hunan Normal University, Changsha, Hunan, PR China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anzhou","family":"Tang","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Head and Neck Surgery, The First Affiliated Hospital of Guangxi Medical University, Nanning, Guangxi, PR China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,1,22]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1186\/2051-5960-1-63"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0b013e31818a08e8"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/ar.24136"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-017-4842-y"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0000000000001189"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0000000000002127"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature14539"},{"key":"e_1_3_3_9_2","first-page":"10574","article-title":"Automatic detection of the inner ears in head CT images using deep convolutional neural networks","author":"Zhang D","year":"2018","unstructured":"Zhang D, Noble JH, Dawant BM.
