Our goal was to develop a methodology that used slice thickness correction, the generation of a time-activity curve and a polar map. Methods: Fourteen normal patients without evidence of coronary artery disease were studied. One hour after intravenous injection of 740-1110 MBq (20-30 mCi) 99mTc-tetrofosmin, ECG-gated SPECT data were acquired by dividing a cardiac cycle into 12 frames. The SPECT data were reconstructed from 11 of 12 frames into 3 views. The reconstruction of these images was repeated after performing slice thickness correction. Excluding the effect of different apex-to-base lengths at any frame during a cardiac cycle, 10 short-axis images with the same slice thickness were obtained. Each short-axis image was divided by 40 radii into 40 segments. The time-activity curve was generated from the total counts included in each segment plus both neighboring segments. Subsequently the curve fitting was performed using the second Fourier function. Results: From fitted curves and their differentials, we calculated end-systolic count, end-diastolic count, percent count increase, uptake, peak contraction rate, peak distention rate and contraction time. Conclusion: The functional polar maps visually demonstrated regional myocardial function. This method is expected to be helpful for assessing regional cardiac function using 99mTc-tetrofosmin.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学大学院医学系研究科量子医療技術学","subitem_description_type":"Other"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Society of Nuclear Medicine"}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://tech.snmjournals.org/cgi/content/short/28/1/29","subitem_relation_type_select":"URI"}}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0091-4916","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_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Onoguchi, Masahisa"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"Maruno, Hirotaka"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takayama, Teruhiko"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"Naoi, Yutaka"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Irimoto, Masahiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Maehara, Nobuyuki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Katayama, Hitoshi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Murata, Hajime"}],"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-ONOGUCHI-M-29.pdf","filesize":[{"value":"393.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ME-PR-ONOGUCHI-M-29.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/12939/files/ME-PR-ONOGUCHI-M-29.pdf"},"version_id":"02f6640d-2183-4879-9394-af7b5848b75b"}]},"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":"New functional polar maps for estimating regional cardiac function using ECG-gated technetium-99m-tetrofosmin SPECT","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"New functional polar maps for estimating regional cardiac function using ECG-gated technetium-99m-tetrofosmin SPECT"}]},"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":"12939","relation_version_is_last":true,"title":["New functional polar maps for estimating regional cardiac function using ECG-gated technetium-99m-tetrofosmin SPECT"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T09:48:18.108407+00:00"}
