However, the correlations between the biological effects and the radiation doses have never been thoroughly evaluated in the majority of cases. In this study, we evaluated the biological radiation effects of measured radiation doses in ICR mice using cone-beam micro-CT scans. Long-term in vivo whole-body micro-CT scans of ICR mice were performed for a duration of 4 weeks. Although a scanning frequency of three scans per week is higher than that necessary for conventional studies, this study represents particular cases where the subjects may undergo an extreme number of examinations. The average X-ray dose of a CT scan measures 16.19 mGy at the center of a phantom and 16.24 mGy at an offset position of 7.5 mm from the center of the phantom. The total average dose at the center of the phantom during the 4-week scanning period was 194.3 mGy. No significant radiation effects were observed in the weight gain curves, organ weights, blood analyses, litter sizes, reared offspring sizes, and the histopathologic results. Therefore, it is unlikely that the measured doses for the CT scans caused any radiation damage in the mice.","subitem_description_type":"Abstract"}]},"item_8_relation_13":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"26441335","subitem_relation_type_select":"PMID"}}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1007/s12194-015-0334-1","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1865-0333","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":"Miyahara, Nobuyuki"}],"nameIdentifiers":[{"nameIdentifier":"476789","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kokubo, Toshiaki"}],"nameIdentifiers":[{"nameIdentifier":"476790","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hara, Yukihiro"}],"nameIdentifiers":[{"nameIdentifier":"476791","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamada, Ayuta"}],"nameIdentifiers":[{"nameIdentifier":"476792","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koike, Takafumi"}],"nameIdentifiers":[{"nameIdentifier":"476793","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Arai, Yoshinori"}],"nameIdentifiers":[{"nameIdentifier":"476794","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"宮原 信幸","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"476795","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小久保 年章","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"476796","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":"Evaluation of X-ray doses and their corresponding biological effects on experimental animals in cone-beam micro-CT scans (R-mCT2).","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Evaluation of X-ray doses and their corresponding biological effects on experimental animals in cone-beam micro-CT scans (R-mCT2)."}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-10-12"},"publish_date":"2016-10-12","publish_status":"0","recid":"47566","relation_version_is_last":true,"title":["Evaluation of X-ray doses and their corresponding biological effects on experimental animals in cone-beam micro-CT scans (R-mCT2)."],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:38:16.023374+00:00"}
