To 36 patients with ischemic cerebrovascular disease, we performed both MRA and CA. MRA was performed on a 1.5T Shimazu SMT-150X. We divided the findings of the main trunk of the intracranial major arteries into four categories based on stenosis; 0～15%, normal; 16～49%, mild; 50～99%, severe; and totally occluded. Three neurologists read each angiograms independently without clinical data, and assessed the correlation of each findings. Basilar and vertebral arteries were excluded due to inadequate imaging by MRA. 59 internal carotid arteries (ICA), 55 anterior cerebral arteries (ACA), 55 middle cerebral arteries (MCA), and 40 posterior cerebral arteries (PCA) were examined. The entire accuracy was 90.4 % (209 vessels), the overestimation 8.6 % (18 vessels), and the underestimation 1% (2 vessels). The accuracy of MRA in each categories was 95% in normal, 44% in mild, 82% in severe, and 100 % in total occlusion. The accuracy in each arteries was 88% in ICA, 91% in ACA, 89% in MCA, and 95% in PCA. Our study suggest that MRA is useful for the finding the state of the main trunk of the intracranial major arteries, but we have to be careful with overestimation.","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"120195","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Onishi, Yoji"}]},{"nameIdentifiers":[{"nameIdentifier":"120196","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sato, Aki"}]},{"nameIdentifiers":[{"nameIdentifier":"120197","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Onoda, Kurazou"}]},{"nameIdentifiers":[{"nameIdentifier":"120198","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yamazaki, Motoyoshi"}]},{"nameIdentifiers":[{"nameIdentifier":"120199","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Oyake, Mutsuo"}]}]},"item_7_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟医学会"}]},"item_7_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_7_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00182415","subitem_source_identifier_type":"NCID"}]},"item_7_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00290440","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"大西, 洋司"}],"nameIdentifiers":[{"nameIdentifier":"120190","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"佐藤, 晶"}],"nameIdentifiers":[{"nameIdentifier":"120191","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小野田, 倉三"}],"nameIdentifiers":[{"nameIdentifier":"120192","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山崎, 元義"}],"nameIdentifiers":[{"nameIdentifier":"120193","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小宅, 睦郎"}],"nameIdentifiers":[{"nameIdentifier":"120194","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-08-08"}],"displaytype":"detail","filename":"108(6)_411-414.pdf","filesize":[{"value":"727.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"108(6)_411-414.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/19302/files/108(6)_411-414.pdf"},"version_id":"e5ad8842-3a6e-44fe-b35a-e9421afa5613"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Cerebral angiography","subitem_subject_scheme":"Other"},{"subitem_subject":"Magnetic resonance angiography","subitem_subject_scheme":"Other"},{"subitem_subject":"Ischemic cerebrovascular disease","subitem_subject_scheme":"Other"},{"subitem_subject":"MR アンギオグラフィー","subitem_subject_scheme":"Other"},{"subitem_subject":"脳血管撮影","subitem_subject_scheme":"Other"},{"subitem_subject":"脳梗塞","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"2)脳梗塞のMRI : Conventional angiographyとの比較(シンポジウム 画像診断の最近の進歩と問題点, 第490回新潟医学会)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"2)脳梗塞のMRI : Conventional angiographyとの比較(シンポジウム 画像診断の最近の進歩と問題点, 第490回新潟医学会)"},{"subitem_title":"2)脳梗塞のMRI : Conventional angiographyとの比較(シンポジウム 画像診断の最近の進歩と問題点, 第490回新潟医学会)","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1149"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-02-10"},"publish_date":"2016-02-10","publish_status":"0","recid":"19302","relation_version_is_last":true,"title":["2)脳梗塞のMRI : Conventional angiographyとの比較(シンポジウム 画像診断の最近の進歩と問題点, 第490回新潟医学会)"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:50:15.637201+00:00"}
