Cervical LN metastases in 17 patients with CUP and cervical LN involvement in 17 patients with ML were assessed by 18F-FDG PET/CT. The texture features were obtained in the total cross-sectional area (CSA) of the targeted LN, following the contour of the largest cervical LN on unenhanced CT. Values for the max standardized uptake value (SUVmax) and the mean SUV value (SUVmean), and 34 texture features were compared using a Mann-Whitney U test. The diagnostic accuracy and area under the curve (AUC) of the combination of the texture features were evaluated by support vector machine (SVM) with nested cross-validation. The SUVmax and SUVmean did not differ significantly between cervical LN metastases from CUP and cervical LN involvement from ML. However, significant differences of 9 texture features of the total CSA were observed (p = 0.001 – 0.05). The best AUC value of 0.851 for the texture feature of the total CSA were obtained from the correlation in the gray-level co-occurrence matrix features. SVM had the best AUC and diagnostic accuracy of 0.930 and 84.8%. Radiomics analysis appears to be useful for differentiating cervical LN metastasis from CUP and cervical LN involvement of ML on unenhanced CT.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_9_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/nagjms.84.2.269", "subitem_identifier_reg_type": "JaLC"}]}, "item_9_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Nagoya University Graduate School of Medicine, School of Medicine", "subitem_publisher_language": "en"}]}, "item_9_relation_43": {"attribute_name": "関連情報", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://www.med.nagoya-u.ac.jp/medlib/nagoya_j_med_sci/842.html", "subitem_relation_type_select": "URI"}}]}, "item_9_rights_12": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International", "subitem_rights_language": "en", "subitem_rights_resource": "http://creativecommons.org/licenses/by-nc-nd/4.0/"}]}, "item_9_source_id_7": {"attribute_name": "収録物識別子", "attribute_value_mlt": [{"subitem_source_identifier": "0027-7622", "subitem_source_identifier_type": "PISSN"}, {"subitem_source_identifier": "2186-3326", "subitem_source_identifier_type": "EISSN"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Tomita, Hayato", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Yamashiro, Tsuneo", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Iida, Gyo", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Tsubakimoto, Maho", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Mimura, Hidefumi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Murayama, Sadayuki", "creatorNameLang": "en"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2022-05-27"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "06_Tomita.pdf", "filesize": [{"value": "4.4 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_5", "mimetype": "application/pdf", "size": 4400000.0, "url": {"objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/2002878/files/06_Tomita.pdf"}, "version_id": "deafc8ac-ed85-4d5e-8383-2841efbe77d7"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "texture", "subitem_subject_scheme": "Other"}, {"subitem_subject": "cancer of unknown primary", "subitem_subject_scheme": "Other"}, {"subitem_subject": "malignant lymphoma", "subitem_subject_scheme": "Other"}, {"subitem_subject": "cervical lymphadenopathy", "subitem_subject_scheme": "Other"}, {"subitem_subject": "machine learning", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Radiomics analysis for differentiating of cervical lymphadenopathy between cancer of unknown primary and malignant lymphoma on unenhanced computed tomography", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Radiomics analysis for differentiating of cervical lymphadenopathy between cancer of unknown primary and malignant lymphoma on unenhanced computed tomography", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1653611787117"], "permalink_uri": "https://doi.org/10.18999/nagjms.84.2.269", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2022-05-27"}, "publish_date": "2022-05-27", "publish_status": "0", "recid": "2002878", "relation": {}, "relation_version_is_last": true, "title": ["Radiomics analysis for differentiating of cervical lymphadenopathy between cancer of unknown primary and malignant lymphoma on unenhanced computed tomography"], "weko_shared_id": -1}
