Digitized mammograms require evaluation of performance to assure medical image quality.<\/jats:p>\n                  <jats:p>Purpose: To compare the diagnostic accuracy in the interpretation of breast masses using original screen-film mammograms versus digitized images.<\/jats:p>\n                  <jats:p>Material and Methods: A total of 72 female patients between 55 and 81 years of age suspected of having breast cancer were selected by two non-observing radiologists. Of these, 31 cases were benign lesions and 41 cases were cancer. The mammography films were digitized using a laser film digitizer. Three radiologists, each with more than 10 years of experience in mammography, interpreted the screen-film mammograms and digitized images respectively. The time interval was 4 weeks. A four-point malignancy scale was used, with 1 defined as definitely not malignant, 2 as probably not malignant, 3 as probably malignant, and 4 as definitely malignant. Receiver operating characteristic (ROC) curves, sensitivity, and specificity were compared.<\/jats:p>\n                  <jats:p>Results: The average area-under-the-curve (Az) value of the original screen-film mammograms was 0.921, and the average Az value of the digitized images was 0.859. This difference was not statistically significant ( P=0.131). The detection specificity of extremely dense breasts was lower than that for other breast compositions for both digitized images and screen-film mammograms. No statistical significance in sensitivity and specificity was observed between digitized images and mammograms for each breast composition. Original screen-film mammograms were observed to perform better than digitized images.<\/jats:p>\n                  <jats:p>Conclusion: Digitized images with a spatial resolution of 175 \u00b5m can be used instead of screen-film mammograms in the diagnosis of breast cancer.<\/jats:p>","DOI":"10.1080\/02841850802014610","type":"journal-article","created":{"date-parts":[[2008,5,12]],"date-time":"2008-05-12T13:08:44Z","timestamp":1210597724000},"page":"618-622","source":"Crossref","is-referenced-by-count":3,"title":["Comparison of diagnostic accuracy of breast masses using digitized images versus screen-film mammography"],"prefix":"10.1177","volume":"49","author":[{"given":"Zhigang","family":"Liang","sequence":"first","affiliation":[{"name":"Department of Radiology, Xuanwu Hospital, Capital Medical University, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiangying","family":"Du","sequence":"additional","affiliation":[{"name":"Department of Radiology, Xuanwu Hospital, Capital Medical University, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiabin","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Radiology, Xuanwu Hospital, Capital Medical University, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xinyu","family":"Yao","sequence":"additional","affiliation":[{"name":"Department of Radiology, Xuanwu Hospital, Capital Medical University, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yanhui","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Radiology, Xuanwu Hospital, Capital Medical University, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kuncheng","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Radiology, Xuanwu Hospital, Capital Medical University, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2008,7,1]]},"container-title":["Acta Radiologica"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1080\/02841850802014610","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1080\/02841850802014610","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T13:51:15Z","timestamp":1777384275000},"score":1,"resource":{"primary":{"URL":"http:\/\/journals.sagepub.com\/doi\/10.1080\/02841850802014610"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2008,7]]},"references-count":0,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2008,7]]}},"alternative-id":["10.1080\/02841850802014610"],"URL":"https:\/\/doi.org\/10.1080\/02841850802014610","relation":{},"ISSN":["0284-1851","1600-0455"],"issn-type":[{"value":"0284-1851","type":"print"},{"value":"1600-0455","type":"electronic"}],"subject":[],"published":{"date-parts":[[2008,7]]}}}
