On a 1.5-T MRI, modulus images of 7-9 gradient-echoes were obtained by MRM-GRE sequence at a time. A real part of the first echo image was also reconstructed to differentiate below and above the 50 percent fat fraction. The fat fraction and R2* were obtained from the parameters of a theoretically fitted formula with each echo signal. R2* and fat fraction were measured with MRM-GRE in the phantom and the liver in normal volunteers (n=6) and patients with fatty liver (n=4) . MRI-derived fat fraction of the phantom was in good agreement with the actual value, and R2* of the phantom showed a strongly positive correlation with the actual iron content. MRI-derived fat fraction in fatty liver was significantly higher than that in the normal volunteers. However, no significant difference in R2* was found between fatty liver and normal volunteers. These results show that the MRM-GRE enables to differentiate the causes of signal reduction whether increasing R2*or increasing fat fraction. The MRM-GRE method makes it possible to simply and accurately assess the fat content and the iron content.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学医薬保健研究域保健学系","subitem_description_type":"Other"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"医用画象情報学会"}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.mii-sci.jp/","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/130000138572","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.jstage.jst.go.jp/article/mii/26/3/26_64/_article","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright (c) 2009 by 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":"小野, 絵理"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"宮地, 利明"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"大野, 直樹"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"笠井, 治昌"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"原, 真咲"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"芝本, 雄太"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"川野, 誠"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"朝日, 美幸"}],"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-64.pdf","filesize":[{"value":"731.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ME-PR-MIYATI-T-64.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/13378/files/ME-PR-MIYATI-T-64.pdf"},"version_id":"0e3b44d8-36a2-45d7-a98c-1fcad5cb000f"}]},"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":"MRM-GRE法を用いた肝臓の鉄含有量および脂肪含有率の同時測定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"MRM-GRE法を用いた肝臓の鉄含有量および脂肪含有率の同時測定"},{"subitem_title":"Simultaneous R2* and Fat Fraction Determination of the Liver with Modulus and Real Multiple Gradient-echo MRI","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":"13378","relation_version_is_last":true,"title":["MRM-GRE法を用いた肝臓の鉄含有量および脂肪含有率の同時測定"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T01:06:10.642390+00:00"}
