Eleven patients with vertebrobasilar ischemia underwent dynamic CT on admission and/or during the follow-up period. The time of appearance (TA) and time to peak (TTP) were mapped and differences in TA (ΔTA) and TTP (ΔTTP) between the bilateral middle cerebral artery and posterior cerebral artery (PGA) territories were calculated. Conventional angiography and brain imaging including CT and magnetic resonance imaging were also performed. The TA and TTP maps obtained within 48 hours after onset exhibited time delay in eight of nine patients in the bilateral PGA territories. ΔTA and ΔTTP were greater in patients with stenosis or occlusion of the bilateral vertebral arteries or the basilar artery, and in patients without collateral circulation via the posterior communicating arteries than in control subjects. Furthermore, TA and TTP normalized dramatically in patients with recanalization of the arteries. ΔTA and ΔTTP were also normalized. ΔTA and ΔTTP were negatively correlated with the time from onset to examination. Dynamic CT can provide important information in patients with vertebrobasilar ischemic stroke, and may allow the diagnosis of acute ischemia and monitoring of the course.","subitem_description_type":"Abstract"}]},"item_2_description_40":{"attribute_name":"資源タイプ(DSpace)","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本脳神経外科学会"}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"rights: 本文データは日本脳神経外科学会の許諾に基づきCiNiiから複製したものである"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00358613","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"04708105","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Nagahori, Takeshi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hirashima, Yutaka"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Umemura, Kimiko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nishijima, Michiharu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kuwayama, Naoya"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kubo, Michiya"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Endo, Shunro"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-15"}],"displaytype":"detail","filename":"shinkeigeka04-105.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"shinkeigeka04-105.pdf","url":"https://toyama.repo.nii.ac.jp/record/2243/files/shinkeigeka04-105.pdf"},"version_id":"1800014e-99b9-4d33-8aac-55dacab3b76b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"dynamic computed tomography","subitem_subject_scheme":"Other"},{"subitem_subject":"vertebrobasilar ischemic stroke","subitem_subject_scheme":"Other"},{"subitem_subject":"basilar artery occlusion","subitem_subject_scheme":"Other"},{"subitem_subject":"collateral circulation","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Supratentorial Dynamic Computed Tomography for the Diagnosis of Vertebrobasilar Ischemic Stroke","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Supratentorial Dynamic Computed Tomography for the Diagnosis of Vertebrobasilar Ischemic Stroke"}]},"item_type_id":"2","owner":"3","path":["442"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-01-30"},"publish_date":"2008-01-30","publish_status":"0","recid":"2243","relation_version_is_last":true,"title":["Supratentorial Dynamic Computed Tomography for the Diagnosis of Vertebrobasilar Ischemic Stroke"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-25T13:54:46.563277+00:00"}
