Methods: Images of the phantom containing 123I-MIBG were acquired on the cameras in 10 hospitals (11 camera types) to determine the relationship between H/M ratios using different collimators: low-energy (LE) and mediumenergy (ME)/low-medium-energy (LME) collimators. The effect of standardization on the ME-comparable H/M ratio was examined in two settings: a Japanese standard MIBG database (n=62) and multicentre studies (n=49). In a multicentre study, probable Alzheimer's disease (AD, n=18) and probable dementia with Lewy bodies (DLB, n=31) were studied and standardized by the calibration phantom method. Results: Linear regression equations between LE and ME collimators were obtained for the phantom study in all institutions. When the H/M ratio with an LE collimator wascorrected based upon the calibration phantom, the corrected values were comparable to those obtained using ME collimators. The standard database also exhibited a normal distribution after standardization as determined by skewness and goodness-of-fit test. A mixture of the populations by LE and ME collimators showed significant separation of AD and DLB groups (F ratio=24.9 for the late H/M), but the corrected values resulted in higher F ratios for both early and late H/M (F ratio=34.9 for the late H/M). Conclusion: Standardization of H/M ratios by the heartchest calibration phantom method is feasible among different collimator types. This method could be practically used for multicentre comparison of H/M ratios. © Springer-Verlag 2011.","subitem_description_type":"Abstract"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer-Verlag"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1007/s00259-011-1963-1","subitem_relation_type_select":"DOI"}}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA1161516X","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1619-7070","subitem_source_identifier_type":"ISSN"}]},"item_4_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":"Nakajima, Kenichi"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Okuda, Koichi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsuo, Shinro"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"ME-PR-NAKAJIMA-K-113.pdf","filesize":[{"value":"679.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ME-PR-NAKAJIMA-K-113.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/13680/files/ME-PR-NAKAJIMA-K-113.pdf"},"version_id":"7d90574a-6447-4042-80e5-606f66d42d89"}]},"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":"Standardization of metaiodobenzylguanidine heartto mediastinum ratio using a calibration phantom: Effects of correction on normal databases and a multicentre study","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Standardization of metaiodobenzylguanidine heartto mediastinum ratio using a calibration phantom: Effects of correction on normal databases and a multicentre study"}]},"item_type_id":"4","owner":"3","path":["1134"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"13680","relation_version_is_last":true,"title":["Standardization of metaiodobenzylguanidine heartto mediastinum ratio using a calibration phantom: Effects of correction on normal databases and a multicentre study"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T16:58:23.977961+00:00"}
