It is essential to assess liver reserve capacity and follow-up post-CIRT value for the long term. In this study, we evaluated the usefulness of 99mTc-GSA dynamic scintigraphy for the follow-up assessment of liver reserve capacity in patients before and after CIRT.\n[Materials and Methods]\nEleven patients who received 99mTc-GSA scintigraphy imaging before CIRT, and twice during 3-18 months after CIRT were enrolled in this investigation. After intravenous injection of 99mTc-GSA, dynamic and SPECT imaging were performed using a gamma camera. The maximal GSA removal rate (GSA-Rmax), GSA-Rmax of the predicted residual liver after CIRT (GSA-RL) were calculated by applying 99mTc-GSA dynamics of heart and liver to a five-compartment model. GSA-Rmax was followed before CIRT and twice after CIRT. \n[Results]\nGSA-RL before CIRT and GSA-Rmax of first post-CIRT (3-12 months after CIRT), GSA-Rmax of second post-CIRT (6-18 months after CIRT) were 0.45 ± 0.17, 0.38 ± 0.12, 0.44 ± 0.16 mg/min, respectively (n.s.). The residual liver reserve after first and second post-CIRT may reflect long-term liver reserve.\n[Conclusion] \n99mTc-GSA scintigraphy was useful for the follow-up assessment of liver reserve capacity in patients before and after CIRT for liver tumors.\n","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"第80回日本医学放射線学会総会","subitem_description_type":"Other"}]},"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":"山崎, 香奈"}],"nameIdentifiers":[{"nameIdentifier":"952244","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"西井, 龍一"}],"nameIdentifiers":[{"nameIdentifier":"952245","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"牧島, 弘和"}],"nameIdentifiers":[{"nameIdentifier":"952246","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"金子, 崇"}],"nameIdentifiers":[{"nameIdentifier":"952247","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"水谷, 陽一"}],"nameIdentifiers":[{"nameIdentifier":"952248","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田村, 謙太郎"}],"nameIdentifiers":[{"nameIdentifier":"952249","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"東, 達也"}],"nameIdentifiers":[{"nameIdentifier":"952250","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"辻, 比呂志"}],"nameIdentifiers":[{"nameIdentifier":"952251","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kana, Yamazaki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"952252","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ryuichi, Nishii","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"952253","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hirokazu, Makishima","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"952254","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takashi, Kaneko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"952255","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kentaro, Tamura","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"952256","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tatsuya, Higashi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"952257","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hiroshi, Tsuji","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"952258","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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"99mTc-GSAシンチグラフィによる肝腫瘍重粒子線治療後患者の肝予備能評価","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"99mTc-GSAシンチグラフィによる肝腫瘍重粒子線治療後患者の肝予備能評価"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-06-01"},"publish_date":"2021-06-01","publish_status":"0","recid":"82904","relation_version_is_last":true,"title":["99mTc-GSAシンチグラフィによる肝腫瘍重粒子線治療後患者の肝予備能評価"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:08:08.405545+00:00"}
