In DCE-MRI analysis, two parameters, SIe and Rdown, were measured. SIe is a median value for the degree of signal intensity change in all selected pixels in the tumor at 1-2 min after contrast agent injection. Rdown is the ratio of the number of down-sloped pixels to that of all selected pixels 3-7 min after injection. The tumor volume reduction rate (TVRR) was measured by MRI-based volumetry in pre- and post-radiotherapy transverse T2-weighted images.\n[Results]\nOverall, TVRR was significantly correlated to both SIe (r=0.37, P=.015) and Rdown (r=0.73, P<.0001). In the separate patient groups, SIe but not Rdown was significantly different between the adenocarcinoma and SCC patients (t=3.64, P<.001). TVRR was not correlated to SIe in any group. TVRR was significantly correlated to Rdown in adenocarcinoma patients (r=0.78, P<.001) but not in SCC patients.\n[Conclusion]\nSIe may reflect differences in histological characteristics. Rdown may be useful for predicting the response to radiotherapy of uterine carcinoma.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.mri.2008.07.007","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0730-725X","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":"Takayama, Yukihisa"}],"nameIdentifiers":[{"nameIdentifier":"464783","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohno, Tatsuya"}],"nameIdentifiers":[{"nameIdentifier":"464784","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kishimoto, Riwa"}],"nameIdentifiers":[{"nameIdentifier":"464785","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kato, Shingo"}],"nameIdentifiers":[{"nameIdentifier":"464786","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoneyama, Ryuichi"}],"nameIdentifiers":[{"nameIdentifier":"464787","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kandatsu, Susumu"}],"nameIdentifiers":[{"nameIdentifier":"464788","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsujii, Hirohiko"}],"nameIdentifiers":[{"nameIdentifier":"464789","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Obata, Takayuki"}],"nameIdentifiers":[{"nameIdentifier":"464790","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高山 幸久","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"464791","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大野 達也","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"464792","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"岸本 理和","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"464793","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"加藤 眞吾","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"464794","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"米山 隆一","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"464795","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"神立 進","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"464796","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"辻井 博彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"464797","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小畠 隆行","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"464798","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Prediction of early response to radiotherapy of uterine carcinoma with dynamic contrast-enhanced MR imaging using pixel analysis of MR perfusion imaging","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Prediction of early response to radiotherapy of uterine carcinoma with dynamic contrast-enhanced MR imaging using pixel analysis of MR perfusion imaging"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-11-25"},"publish_date":"2013-11-25","publish_status":"0","recid":"46622","relation_version_is_last":true,"title":["Prediction of early response to radiotherapy of uterine carcinoma with dynamic contrast-enhanced MR imaging using pixel analysis of MR perfusion imaging"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:49:34.966355+00:00"}
