We hypothesized that the value of the H/M ratio could be standardized to the various camera-collimator combinations. Methods and results: Standard phantoms consisting of the heart and mediastinum were made. A low-energy high-resolution (LEHR) collimator and a medium-energy (ME) collimator were used. We examined multi-window correction methods with 123I- dual-window (IDW) acquisition, and planar images were obtained with IDW correction and the LEHR collimator. The images were obtained using the following gamma camera systems: GCA 9300A (Toshiba, Tokyo), E.CAM Signature (Toshiba/Siemens, Tokyo) and Varicam (GE, Tokyo). Cardiac phantom studies demonstrated that contamination of the H/M count ratio was greater with the LEHR collimator and least with the ME collimator. The corrected H/M ratio with the LEHR collimator was similar to that with ME collimators. The uncorrected H/M ratio with the ME collimator was linearly related to the H/M ratio with IDW correction with the LEHR collimator. The relationship between the uncorrected H/M ratios determined with the LEHR (E.CAM) and the ME collimators was y = 0.56x + 0.49, where y = H/M ratio with the E.CAM and x = H/M ratio with the ME collimator. The average normal values for the low-energy collimator (n=18) were 2.2±0.2 (initial H/M ratio) and 2.42±0.2 (delayed H/M ratio), and for the low/medium-energy (LME) collimator (n=14) were 2.63±0.25 (initial H/M ratio) and 2.87±0.19 (delayed H/M ratio). H/M ratios in previous clinical studies using LEHR collimators are comparable to those with ME collimators. Conclusion: The IDW-corrected H/M ratios determined with the LEHR collimator were similar to those determined with the ME collimator. This finding could make it possible to standardize the H/M ratio in planar imaging among various collimators in the clinical setting. © 2008 Springer-Verlag.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学附属病院核医学診療科","subitem_description_type":"Other"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer Verlag (Germany)"}]},"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/s00259-008-0971-2","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":"Matsuo, Shinro"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"Nakajima, Kenichi"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Okuda, Koichi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kawano, Masaya"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ishikawa, Takehiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hosoya, Tetsuo"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Taki, Junichi"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Kinuya, Seigo"}],"nameIdentifiers":[{},{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-05"}],"displaytype":"detail","filename":"HO-PR-MATSUO-S-560.pdf","filesize":[{"value":"345.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"HO-PR-MATSUO-S-560.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/27043/files/HO-PR-MATSUO-S-560.pdf"},"version_id":"c4c7df65-f2b9-4b86-bf5c-d17d96a8a29b"}]},"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 the heart-to-mediastinum ratio of 123I- labelled-metaiodobenzylguanidine uptake using the dual energy window method: Feasibility of correction with different camera-collimator combinations","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Standardization of the heart-to-mediastinum ratio of 123I- labelled-metaiodobenzylguanidine uptake using the dual energy window method: Feasibility of correction with different camera-collimator combinations"}]},"item_type_id":"4","owner":"3","path":["1763"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-05"},"publish_date":"2017-10-05","publish_status":"0","recid":"27043","relation_version_is_last":true,"title":["Standardization of the heart-to-mediastinum ratio of 123I- labelled-metaiodobenzylguanidine uptake using the dual energy window method: Feasibility of correction with different camera-collimator combinations"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-27T21:14:23.022249+00:00"}
