The images were interpreted twice by six radiologists both on CR film (2510 x 2000 pixels x 10bits, 0.1mm spatial resolution) and on ao CRT monitor (1568 x 1152 pixels x 10 bits, 0.1 mm pixel size with double expansion) with image processing parameters of a toutine (RN 1.0, RE 0.2), for a calcification (RN9.0, RE4.0) and for a mass (RN7.0, RE2.0). THe forty clinical cases included breast diseases with calcifications, masses, and normal breasts. Two-tailed t-test was performed to analyze interpretation of simulated microcalcifications and masses in the phantom. The receiver operating characteristic (ROC) analysis was performed to evaluate clinical cases.\nResults: In all interpretation studies using both breast phantom and clinical cases, there was no significant difference between the two interpretation methods. However the CRT diagnosis was slightly less accurate than CR film diagnosis due to the lower luminance levels of the CRTmonitor.\nConclusions: Diagnosis via CRT monitor may be substituted for CR film diagnosing breast abnormalities, but the image processing parameters of CRT require improvement to compensate for low luminace.","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0289-0925","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Matsumoto, Tooru"}],"nameIdentifiers":[{"nameIdentifier":"438633","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"et.al"}],"nameIdentifiers":[{"nameIdentifier":"438634","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"松本 徹","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"438635","nameIdentifierScheme":"WEKO"}]}]},"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":"CR mammographyにおけるCRT診断とFilm診断との比較検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"CR mammographyにおけるCRT診断とFilm診断との比較検討"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2006-06-01"},"publish_date":"2006-06-01","publish_status":"0","recid":"44131","relation_version_is_last":true,"title":["CR mammographyにおけるCRT診断とFilm診断との比較検討"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:19:02.244979+00:00"}
