This study aimed to quantitatively evaluate the aneurysm wall characteristics.\nMethods: In 15 unruptured cerebral aneurysms, the surface color of cerebral aneurysms, parent arteries and branches were measured using Commission International del’Eclairage L*a*b*. The values of L* (perceptual lightness), a* (red-green color characteristics) and b* (blue-yellow color characteristics) were compared with color discrimination by two independent neurosurgeons, which was classified into ‘‘red”, ‘‘yellow”, ‘‘white” and ‘‘unjudged”.\nResults: Significantly lower L* and higher a* values were shown in red wall points consistently judged by both neurosurgeons compared with yellow or white wall points, while b* values had no significant differences. Based on these results, a novel index, aneurysm red indicator (ARI) was developed as a ratio of a* to L* values. The ARI had a high sensitivity and specificity to discriminate red walls (0.984 and 0.986, respectively).\nConclusions: ARI could be useful for evaluating thin red walls of cerebral aneurysms. The novel approach using colorimetry may contribute to future hemodynamics analyses related to the aneurysm wall characteristics.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_7_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"本文/Department of Internal Medicine, Kinan Hospital, Minamimuro-gun, Mie, Japan","subitem_description_type":"Other"},{"subitem_description":"5p","subitem_description_type":"Other"}]},"item_7_dissertation_number_60":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲医学第2238号"}]},"item_7_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学"}]},"item_7_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.hest.2021.10.002","subitem_relation_type_select":"DOI"}}]},"item_7_text_31":{"attribute_name":"出版者（ヨミ）","attribute_value_mlt":[{"subitem_text_value":"ミエダイガク"}]},"item_7_text_63":{"attribute_name":"ノート","attribute_value_mlt":[{"subitem_text_value":"Brain Hemorrhages 2022;3(2):57-61に掲載"}]},"item_7_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Doctoral Dissertation / 博士論文"}]},"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":"佐藤, 丈典","creatorNameLang":"ja"},{"creatorName":"サトウ, タケノリ","creatorNameLang":"ja-Kana"},{"creatorName":"Sato, Takenori","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":"2024-05-10"}],"filename":"2023DM0312.pdf","filesize":[{"value":"869 KB"}],"format":"application/pdf","url":{"label":"2023DM0312.pdf","objectType":"fulltext","url":"https://mie-u.repo.nii.ac.jp/record/2000765/files/2023DM0312.pdf"},"version_id":"db58efdd-dfba-4ddf-b430-e7d32afd27e3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Cerebral aneurysm","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Aneurysm wall characteristics","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Colorimetry","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"CIE L*a*b*","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Digital Color Meter","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Aneurysm Red Indicator","subitem_subject_language":"en","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":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Colorimetry for wall appearance study of cerebral aneurysms","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Colorimetry for wall appearance study of cerebral aneurysms","subitem_title_language":"en"}]},"item_type_id":"7","owner":"15","path":["1694066935734"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-05-10"},"publish_date":"2024-05-10","publish_status":"0","recid":"2000765","relation_version_is_last":true,"title":["Colorimetry for wall appearance study of cerebral aneurysms"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2024-05-10T06:27:03.571009+00:00"}
