Dual-phase (the arterial and venous phases) contrast-enhanced computed tomography was performed in 45 consecutive patients (39 men and 6 women;\nage range, 47Y84 years) with 47 lesions of esophageal carcinoma who underwent surgical intervention. Two radiologists independently evaluated the T-staging of esophageal carcinoma on both phases. The Tstaging on both the arterial and venous phase images was compared with the T-staging at histologic evaluation by means of a resected specimen (as the reference standard). Differences in the overall accuracy and sensitivity for the T-staging between the 2 phases were analyzed with the\nMcNemar test.\nResults: The analysis of the interobserver agreement for T-staging showed almost perfect agreement (J = 0.85 on the arterial phase and J = 0.93 on the venous phase). The overall accuracy in the arterial phase was significantly better than that in the venous phase (68% vs 51%,\nP < 0.01). The sensitivity values of the T-staging in the arterial phase were 0% in T1a, 71.4% in T1b, 12.5% in T2, 89.5% in T3, and 100% in T4. The sensitivity values in the venous phase were 0% in T1a, 14.3% in T1b, 0% in T2, 94.7% in T3, and 100% in T4. Statistical significance was apparent in the sensitivity of the T1b lesions.\nConclusion: The arterial phase can improve the accuracy of T-staging of esophageal carcinomas, especially early-staged lesions.","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0363-8715","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":"Umeoka, Shigeaki"}],"nameIdentifiers":[{"nameIdentifier":"456032","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koyama, Takashi"}],"nameIdentifiers":[{"nameIdentifier":"456033","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Watanabe, Go"}],"nameIdentifiers":[{"nameIdentifier":"456034","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Saga, Tsuneo"}],"nameIdentifiers":[{"nameIdentifier":"456035","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kataoka, Masako"}],"nameIdentifiers":[{"nameIdentifier":"456036","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Togashi, Kaori"}],"nameIdentifiers":[{"nameIdentifier":"456037","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hatabu, Hiroto"}],"nameIdentifiers":[{"nameIdentifier":"456038","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"佐賀 恒夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"456039","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":"Preoperative local staging of esophageal carcinoma using dual-phase contrast-enhanced imaging with multi-detector row computed tomography: value of the arterial phase images.","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Preoperative local staging of esophageal carcinoma using dual-phase contrast-enhanced imaging with multi-detector row computed tomography: value of the arterial phase images."}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-07-12"},"publish_date":"2010-07-12","publish_status":"0","recid":"45852","relation_version_is_last":true,"title":["Preoperative local staging of esophageal carcinoma using dual-phase contrast-enhanced imaging with multi-detector row computed tomography: value of the arterial phase images."],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:58:50.999528+00:00"}
