We aimed to evaluate the imaging findings of hepatic metastases from pancreatic carcinomas, especially wedge-shaped enhancement and its etiology.\nMATERIALS AND METHOD. Dynamic CT and MR images were performed in 87 patients with liver metastases from pancreatic carcinomas, and CT during arterial portography (CTAP) and CT during hepatic arteriography (CTHA) in 51 patients.\nRESULTS. In 37 patients, more than one metastatic lesions accompanied with wedge-shaped enhancement on dynamic studies and CHTA, and wedge shaped perfusion defect on CTAP. Six patients showed multiple wedge-shaped enhancement which was initially diagnosed as multiple arterioportal shunts (AP shunts). However, metastatic tumors appeared within the area of wedge-shaped enhancement on follow-up CT and/or MR images After all, 43 of 87 patients (49%) had AP shunt like contrast enhancement adjacent to liver metastases.\nCONCLUSION. Liver metastases from pancreatic carcinomas frequently show transient wedge-shaped enhancement, and should not be misdiagnosed as nontumorous arterioportal shunts.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:16591191, 研究期間(年度):2004-2005","subitem_description_type":"Other"},{"subitem_description":"出典：「膵癌肝転移の画像的特徴の解明: 臨床病理組織学的検討との対比」研究成果報告書　課題番号16591191\n  (KAKEN：科学研究費助成事業データベース（国立情報学研究所）)\n　　　本文データは著者版報告書より作成","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00051135","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_17":{"attribute_name":"公開者","attribute_value_mlt":[{"subitem_publisher":"金沢大学医薬保健研究域医学系"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=00169806"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=00169806","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-16591191/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-16591191/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-16591191/165911912005kenkyu_seika_hokoku_gaiyo/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-16591191/165911912005kenkyu_seika_hokoku_gaiyo/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"蒲田, 敏文"}],"nameIdentifiers":[{"nameIdentifier":"404","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"00169806","nameIdentifierScheme":"金沢大学研究者情報","nameIdentifierURI":"http://ridb.kanazawa-u.ac.jp/public/detail.php?kaken=00169806"},{"nameIdentifier":"00169806","nameIdentifierScheme":"研究者番号","nameIdentifierURI":"https://nrid.nii.ac.jp/nrid/1000000169806"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-06-21"}],"displaytype":"detail","filename":"ME-PR-GABATA-T-kaken 2006-7p.pdf","filesize":[{"value":"367.0 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"ME-PR-GABATA-T-kaken 2006-7p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/44796/files/ME-PR-GABATA-T-kaken 2006-7p.pdf"},"version_id":"77be576e-3783-4612-83f4-23799a2cab50"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"膵癌肝転移の画像的特徴の解明: 臨床病理組織学的検討との対比","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"膵癌肝転移の画像的特徴の解明: 臨床病理組織学的検討との対比"},{"subitem_title":"Imaging Diagnosis of Hepatic Metastases of Pancreatic Carcinomas : Significance of Transient Wedge-shaped Contrast Enhancement Mimicking Arterioportal Shunt","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2828"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-06-21"},"publish_date":"2018-06-21","publish_status":"0","recid":"44796","relation_version_is_last":true,"title":["膵癌肝転移の画像的特徴の解明: 臨床病理組織学的検討との対比"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-07-01T06:20:13.530680+00:00"}
