For each rabbit, two or three RFA sessions were performed using an electrode needle. Ablation time, temperature around the tip of RFA needle at the end of RFA, ablation volume on fat-suppressed T1-weighted image in the hepatobiliary phase, and coagulative necrosis area on histopathology were measured and compared between the three groups using the Kruskal-Wallis paired Mann-Whitney U tests. \n\nResults:\nIn 43 RFA sessions (group 1, 15; group 2, 14; group 3, 14), mean tissue temperature in group 3 (77.0 °C ± 7.7 °C) was significantly higher compared to groups 1 (59.2 °C ± 18.8 °C; P = 0.010) and 2 (67.5 °C ± 9.9 °C; P = 0.010). In addition, mean ablation volume and coagulative necrosis in group 3 (2.10 ± 1.37 mm3 and 0.86 ± 0.28 mm2, respectively) were larger compared to groups 1 (0.84 ± 0.30 mm3; P < 0.001 and 0.55 ± 0.26 mm2; P = 0.020, respectively) and 2 (0.89 ± 0.59 mm3; P = 0.002 and 0.60 ± 0.22 mm2; P = 0.024, respectively). \n\nConclusion:\nPortal vein occlusion potentially boosts tissue temperature, ablation volume, and area of histopathologically proven coagulative necrosis during hepatic RFA in the non-cirrhotic liver.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_4_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer Nature","subitem_publisher_language":"en"}]},"item_4_relation_10":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"34231011","subitem_relation_type_select":"PMID"}}]},"item_4_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1007/s00270-021-02822-4","subitem_relation_type_select":"DOI"}}]},"item_4_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2021, Springer Science Business Media, LLC, part of Springer Nature and the Cardiovascular and Interventional Radiological Society of Europe (CIRSE)","subitem_rights_language":"en"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1432-086X","subitem_source_identifier_type":"EISSN"}]},"item_4_version_type_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"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":"INOUE, Akitoshi","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"NITTA, Norihisa","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"IMAI, Yugo","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"TAKAKI, Kai","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"TAKAHASHI, Hiroaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OTA, Shinichi","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"MUKAISHO, Ken-ichi","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"WATANABE, Yoshiyuki","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Radiofrequency ablation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Balloon occlusion","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Portal vein","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Hepatocellular carcinoma","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Liver neoplasms","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"Effect of Portal Vein and Hepatic Artery Occlusion on Radiofrequency Ablation : Animal Experiment Comparing MR and Histology Measurements of the Ablation Zones.","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effect of Portal Vein and Hepatic Artery Occlusion on Radiofrequency Ablation : Animal Experiment Comparing MR and Histology Measurements of the Ablation Zones.","subitem_title_language":"en"}]},"item_type_id":"4","owner":"11","path":["218","262"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-07-13"},"publish_date":"2021-07-13","publish_status":"0","recid":"3941","relation_version_is_last":true,"title":["Effect of Portal Vein and Hepatic Artery Occlusion on Radiofrequency Ablation : Animal Experiment Comparing MR and Histology Measurements of the Ablation Zones."],"weko_creator_id":"11","weko_shared_id":-1},"updated":"2023-10-05T01:48:03.220817+00:00"}
