We found that (1) use of spiral acquisition reduced artifact on DENSE MRI and allows for reproducible quantification of circumferential and radial strain, (2) longitudinal myocardial strain of the right ventricle can be accurately assessed with SENC MRI and (3) speckle tracking of cine MRI and DENSE MRI demonstrated an excellent agreement and moderate agreement for global and regional myocardial strain, respectively, in patients with myocardial infarction.","subitem_description_type":"Abstract"}]},"item_8_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"2011年度～2013年度科学研究費補助金(基盤研究(C))研究成果報告書","subitem_description_type":"Other"}]},"item_8_description_64":{"attribute_name":"科研費番号","attribute_value_mlt":[{"subitem_description":"23591762","subitem_description_type":"Other"}]},"item_8_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学"}]},"item_8_text_18":{"attribute_name":"その他のタイトル","attribute_value_mlt":[{"subitem_text_value":"Assessment of Myocardial Strain with DENSE MRI"}]},"item_8_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Kaken / 科研費報告書"}]},"item_8_version_type_15":{"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":"佐久間, 肇","creatorNameLang":"ja"},{"creatorName":"SAKUMA, Hajime","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"北川, 覚也","creatorNameLang":"ja"},{"creatorName":"KITAGAWA, Kakuya","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"永田, 幹紀","creatorNameLang":"ja"}],"familyNames":[{"familyName":"NAGATA, Motonori","familyNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-18"}],"displaytype":"detail","filename":"30K17529.pdf","filesize":[{"value":"555.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"30K17529.pdf","url":"https://mie-u.repo.nii.ac.jp/record/8058/files/30K17529.pdf"},"version_id":"eae33e7d-d79f-466f-ab52-cf0fad2ca2a9"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"MRI","subitem_subject_scheme":"Other"},{"subitem_subject":"Myocardial Strain","subitem_subject_scheme":"Other"},{"subitem_subject":"DENSE MRI","subitem_subject_scheme":"Other"},{"subitem_subject":"SENC MRI","subitem_subject_scheme":"Other"},{"subitem_subject":"Ischemic Heart Disease","subitem_subject_scheme":"Other"},{"subitem_subject":"Myocardial Infarction","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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"３テスラＤＥＮＳＥ　ＭＲＩによる左室壁内心筋ストレインの定量的評価","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"３テスラＤＥＮＳＥ　ＭＲＩによる左室壁内心筋ストレインの定量的評価","subitem_title_language":"ja"}]},"item_type_id":"8","owner":"15","path":["1692670356714"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2016-01-15"},"publish_date":"2016-01-15","publish_status":"0","recid":"8058","relation_version_is_last":true,"title":["３テスラＤＥＮＳＥ　ＭＲＩによる左室壁内心筋ストレインの定量的評価"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-11-07T04:16:28.646707+00:00"}
