Estimating residual radioactivity in lymphatic nodes before a biopsy in advance is useful for reducing surgical operation time. The purpose of this study was to estimate total radioactivity of a small hot spot in single-photon emission computed tomography (SPECT) of a torso phantom. Methods: Cross-calibration study was performed to convert counts in SPECT images to radioactivity. A simulation study was performed to estimate the size of volume of interest (VOI) covering a hot spot corrupted with full width at half maximum (FWHM) between 8 and 16 mm. The estimation of total radioactivity was validated in a torso phantom study using small sources. Results: True radioactivity was approximately equal to integrated values of hot spots using the VOI with a diameter of 40 mm in our simulation study. The difference was less than18% in cases of more than 9.4 kBq. Conclusions: The total radioactivity in small sources simulating a typical sentinel node was estimated from SPECT images using a VOI of 40 mm in a torso phantom study. Because the difference from actual values were less than 10% on average when radioactivities were more than 9.4 kBq, the total radioactivity of a lymph node can be estimated in a clinical examination.","subitem_description_type":"Abstract"}]},"item_6_description_40":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_6_relation_11":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"25738561","subitem_relation_type_select":"PMID"}}]},"item_6_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1097/MNM.0000000000000294","subitem_relation_type_select":"DOI"}}]},"item_6_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10624879","subitem_source_identifier_type":"NCID"}]},"item_6_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"01433636","subitem_source_identifier_type":"ISSN"}]},"item_6_version_type_16":{"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":"Kitamura, Hideaki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kono, Yuzuru"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Murano, Takeshi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hiroi, Kenta"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ihara, Kanyu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Aso, Tomohiko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Inoue, Kazumasa"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fukushi, Masahiro"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-08-04"}],"displaytype":"detail","filename":"10801-001.pdf","filesize":[{"value":"2.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"10801-001.pdf","url":"https://tokyo-metro-u.repo.nii.ac.jp/record/4273/files/10801-001.pdf"},"version_id":"494e9a1e-62e0-419f-a5ed-fde5688168b7"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"sentinel lymph node","subitem_subject_scheme":"Other"},{"subitem_subject":"total radioactivity","subitem_subject_scheme":"Other"},{"subitem_subject":"SPECT","subitem_subject_scheme":"Other"},{"subitem_subject":"quantification","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":"Estimation of radioactivity in single photon emission computed tomography for sentinel lymph node biopsy in a torso phantom study","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Estimation of radioactivity in single photon emission computed tomography for sentinel lymph node biopsy in a torso phantom study"}]},"item_type_id":"6","owner":"3","path":["684"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-04-14"},"publish_date":"2016-04-14","publish_status":"0","recid":"4273","relation_version_is_last":true,"title":["Estimation of radioactivity in single photon emission computed tomography for sentinel lymph node biopsy in a torso phantom study"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T18:00:57.747333+00:00"}
