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\u003c 0.001)。GTVとBTVの間には強い相関を認めた(r=0.952,\np\u003c0.001)。\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\u003c0.001)。\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"], "permalink_uri": "https://repo.qst.go.jp/records/45331", "pubdate": {"attribute_name": "公開日", "attribute_value": "2008-12-01"}, "publish_date": "2008-12-01", "publish_status": "0", "recid": "45331", "relation": {}, "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_shared_id": -1}
