Thus, decreased blood flow should be observed as a reduction of the variation of X-ray translucency. We performed the present study to investigate the feasibility of pulmonary blood flow evaluation with a dynamic flat-panel detector (FPD). Sequential chest radiographs of 14 subjects were obtained with a dynamic FPD system. The changes in pixel value in each local area were measured and mapped on the original image by use of a gray scale in which small and large changes were shown in white and black, respectively. The resulting images were compared to the findings in perfusion scans. The cross-correlation coefficients of the changes in pixel value and radioactivity counts in each local area were also computed. In all patients, pulmonary blood flow disorder was indicated as a reduction of changes in pixel values on the mapping image, and a correlation was observed between the distribution of changes in pixel value and those in radioactivity counts (0.7 ≤ r, 3 cases; 0.4 ≤ r < 0.7, 7 cases; 0.2 ≤ r < 0.4, 4 cases). The results indicated that the distribution of changes in pixel value could provide a relative measure related to pulmonary blood flow. The present method is potentially useful for evaluating pulmonary blood flow as an additional examination in conventional chest radiography. © 2009 Japanese Society of Radiological Technology and Japan Society of Medical Physics.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学医薬保健研究域保健学系","subitem_description_type":"Other"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00013273","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer Verlag (Germany) / Japan Society of Medical Physics = 日本放射線技術学会"}]},"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/s12194-009-0074-1","subitem_relation_type_select":"DOI"}}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA12236881","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1865-0333","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":"Tanaka, Rie"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Sanada, Shigeru"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"Fujimura, Masaki"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"Yasui, Masahide"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Hayashi, Norio"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tsuji, Shiro"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Okamoto, Hiroyuki"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Nanbu, Yuko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsui, Osamu"}],"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-TANAKA-R-40.pdf","filesize":[{"value":"463.8 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"ME-PR-TANAKA-R-40.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/13286/files/ME-PR-TANAKA-R-40.pdf"},"version_id":"a5a96d00-ef39-46f1-92e3-c8afe75034f9"}]},"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":"Development of pulmonary blood flow evaluation method with a dynamic flat-panel detector: quantitative correlation analysis with findings on perfusion scan","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Development of pulmonary blood flow evaluation method with a dynamic flat-panel detector: quantitative correlation analysis with findings on perfusion scan"}]},"item_type_id":"4","owner":"3","path":["4312"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"13286","relation_version_is_last":true,"title":["Development of pulmonary blood flow evaluation method with a dynamic flat-panel detector: quantitative correlation analysis with findings on perfusion scan"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T08:48:10.517880+00:00"}
