However, image-processing parameters for soft-copy reading of digital mammograms have not been established.<\/jats:p>\n                  <jats:p>Purpose: To compare observer performance in detecting breast cancer by soft-copy reading of digital mammograms using a routine image-processing parameter versus each of several high-contrast parameters.<\/jats:p>\n                  <jats:p>Material and Methods: The mammograms of 154 breasts, including 48 abnormal breasts with breast cancer and 106 normal breasts, were examined. Cancers were classified into 34 mass-dominant cancers, 11 microcalcification-dominant cancers, two cancers showing only architectural distortion, and one cancer without abnormal findings. All mammograms were performed using a computed radiography (CR) system. Each image was processed using GA (1.2), which was the contrast parameter recommended by the manufacturer for hard-copy film, GA (1.4), GA (1.6), and GA (1.8). These images were displayed on 5-megapixel (M) liquid-crystal display monitors. Five experienced radiologists classified them into BI-RADS category 1\u20132 or 3\u20135, and were also asked to rate the images on a scale of 0 to 100 for the likelihood of the presence of masses and microcalcifications in each breast.<\/jats:p>\n                  <jats:p>\n                    Results: In mass-dominant cancers of dense breast tissue, the mean sensitivities of GA (1.2), GA (1.4), GA (1.6), and GA (1.8) were 32.7, 38.2, 36.4, and 40.0, and the A\n                    <jats:sub>Z<\/jats:sub>\n                    values were 0.67, 0.73, 0.71, and 0.73, respectively; in microcalcification-dominant cancers, the mean sensitivities were 80.0, 74.5, 80.0, and 78.2, respectively; however, there were no significant differences among them.\n                  <\/jats:p>\n                  <jats:p>\n                    Conclusion: High-contrast parameters tended to show relatively high sensitivity and A\n                    <jats:sub>Z<\/jats:sub>\n                    values in the detection of masses in dense breast tissue, but relatively low sensitivity for microcalcifications.\n                  <\/jats:p>","DOI":"10.3109\/02841850903321625","type":"journal-article","created":{"date-parts":[[2010,1,20]],"date-time":"2010-01-20T08:29:58Z","timestamp":1263976198000},"page":"15-20","source":"Crossref","is-referenced-by-count":5,"title":["Detection of breast cancer by soft-copy reading of digital mammograms: Comparison between a routine image-processing parameter and high-contrast parameters"],"prefix":"10.1177","volume":"51","author":[{"given":"Takeshi","family":"Kamitani","sequence":"first","affiliation":[{"name":"Department of Clinical Radiology, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hidetake","family":"Yabuuchi","sequence":"additional","affiliation":[{"name":"Department of Clinical Radiology, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroyasu","family":"Soeda","sequence":"additional","affiliation":[{"name":"Department of Clinical Radiology, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshio","family":"Matsuo","sequence":"additional","affiliation":[{"name":"Department of Clinical Radiology, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takashi","family":"Okafuji","sequence":"additional","affiliation":[{"name":"Department of Clinical Radiology, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuji","family":"Sakai","sequence":"additional","affiliation":[{"name":"Department of Health Sciences, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Taro","family":"Setoguchi","sequence":"additional","affiliation":[{"name":"Department of Clinical Radiology, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masamitsu","family":"Hatakenaka","sequence":"additional","affiliation":[{"name":"Department of Clinical Radiology, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nobuhide","family":"Ishii","sequence":"additional","affiliation":[{"name":"Department of Health Sciences, Fuji Film Medical Co., Ltd., Fukuoka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroshi","family":"Honda","sequence":"additional","affiliation":[{"name":"Department of Clinical Radiology, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2010,2,1]]},"container-title":["Acta Radiologica"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.3109\/02841850903321625","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.3109\/02841850903321625","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T13:57:18Z","timestamp":1777384638000},"score":1,"resource":{"primary":{"URL":"http:\/\/journals.sagepub.com\/doi\/10.3109\/02841850903321625"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,2]]},"references-count":0,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2010,2]]}},"alternative-id":["10.3109\/02841850903321625"],"URL":"https:\/\/doi.org\/10.3109\/02841850903321625","relation":{},"ISSN":["0284-1851","1600-0455"],"issn-type":[{"value":"0284-1851","type":"print"},{"value":"1600-0455","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,2]]}}}
