77.2±53.6 cm3, BTV; 58.0±48.0 cm3となり、BTVがGTVより統計学的に有意な低値となった (p< 0.001)。GTVとBTVの間には強い相関を認めた(r=0.952,\np<0.001)。\n\\n直腸癌局所再発症例では、放射線腫瘍医間の標的体積には明らかな差は認めなかった　(F(2, 18)=0.654, MSe=5220.046, p=0.532)、modalityに有意な主効果が見られた\n(F(1, 18)=28.252, MSe=137.496, p<0.001)。\n\\n[結論]直腸癌の局所再発症例でも機能画像(PET/CT)によるtarget volumeと形態画像(CT)による標的体積で有意な差を認めた。","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1040-9564","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"神宮, 啓一"}],"nameIdentifiers":[{"nameIdentifier":"450339","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"武田, 賢"}],"nameIdentifiers":[{"nameIdentifier":"450340","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"目時, 隆博"}],"nameIdentifiers":[{"nameIdentifier":"450341","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小川, 芳弘"}],"nameIdentifiers":[{"nameIdentifier":"450342","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"有賀, 久哲"}],"nameIdentifiers":[{"nameIdentifier":"450343","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山田, 章吾"}],"nameIdentifiers":[{"nameIdentifier":"450344","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高井, 良尋"}],"nameIdentifiers":[{"nameIdentifier":"450345","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"細貝, 良行"}],"nameIdentifiers":[{"nameIdentifier":"450346","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"金田, 朋洋"}],"nameIdentifiers":[{"nameIdentifier":"450347","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"三津谷, 正俊"}],"nameIdentifiers":[{"nameIdentifier":"450348","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"渡邉, 暁"}],"nameIdentifiers":[{"nameIdentifier":"450349","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"神宮 啓一","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"450350","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"武田 賢","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"450351","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小川 芳弘","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"450352","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"有賀 久哲","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"450353","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山田 章吾","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"450354","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高井 良尋","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"450355","nameIdentifierScheme":"WEKO"}]}]},"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":"直腸癌術後再発に対するＰＥＴ／ＣＴ　planningに関する初期研究　〜ＧＴＶとＢＴＶの相違〜","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"直腸癌術後再発に対するＰＥＴ／ＣＴ　planningに関する初期研究　〜ＧＴＶとＢＴＶの相違〜"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-12-01"},"publish_date":"2008-12-01","publish_status":"0","recid":"45331","relation_version_is_last":true,"title":["直腸癌術後再発に対するＰＥＴ／ＣＴ　planningに関する初期研究　〜ＧＴＶとＢＴＶの相違〜"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:04:58.754372+00:00"}
