The aim of our study was to assess the relationship between contrast signal intensity(CI)of ultrasonography(US)and concentration of a perflubutane contrast-agent. Concentrations of the perflubutane solutions in spherically-shaped US phantom filled with pure water were varied with 0, 1.91, 3.81, 7.63, 30.52, 488.28, 1953.13, 7812.5×10-6L/L. Phantom images in each solution were obtained using multi-frequency linear probes with low mechanical-index(MI), i.e., MI of 0.2 at 3.5 and MI of 0.6 at 10 MHz. Then we evaluated the linearity between CIs and the concentrations with double logarithm scale, and time variability of the CI during the scan in each concentration. CIs in dB at each frequency had strong linear correlations with concentration in dB within the actual concentration range of the agent in human body. The CIs were temporally stable during the scan with each condition. The linear and temporally-stable characteristics under above mentioned conditions make it possible to obtain more detailed and quantitative hemodynamic analysis of the tissue.","subitem_description_type":"Abstract"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"医用画像情報学会 = MII: Japan Society of Medical Imaging and Information Sciences"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.11318/mii.28.83","subitem_relation_type_select":"DOI"}}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.jstage.jst.go.jp/browse/mii/-char/ja/","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.mii-sci.jp/","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright © 医用画像情報学会 MII: Japan Society of Medical Imaging and Information Sciences"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN10156808","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0910-1543","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"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":"伊吹, 真紀子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"宮地, 利明"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"形川, 真由"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田島, 尚美"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"沢田, 恵子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"角田, 清志"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"林, 則夫"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"ME-PR-MIYATI-T-83.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ME-PR-MIYATI-T-83.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/13804/files/ME-PR-MIYATI-T-83.pdf"},"version_id":"647c24bf-4637-4ec9-a04b-1a524e8ab818"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ペルフルブタン超音波イメージングによる血流解析の基礎検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ペルフルブタン超音波イメージングによる血流解析の基礎検討"},{"subitem_title":"Phantom study for quantitative measurement of tissue perfusion using perflubutane dynamic contrast-enhanced ultrasonography with low mechanical-index","subitem_title_language":"en"}]},"item_type_id":"4","owner":"3","path":["1134"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"13804","relation_version_is_last":true,"title":["ペルフルブタン超音波イメージングによる血流解析の基礎検討"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T00:58:21.025166+00:00"}
