{"pk":27887,"title":"Texture as a Diagnostic Signal in Mammograms","subtitle":null,"abstract":"Radiologists can discriminate between normal and abnormalbreast tissue at a glance, suggesting that radiologists might beusing some “global signal” of abnormality. Our study inves-tigated whether texture descriptions can be used to character-ize the global signal of abnormality and whether radiologistsuse this information during interpretation. Synthetic imageswere generated using a texture synthesis algorithm trained ontexture descriptions extracted from sections of mammograms.Radiologists completed a task that required rating the abnor-mality of briefly presented tissue sections. When the abnormaltissue had no visible lesion, radiologists seemed to use texturedescriptions; performance was similar across real and synthe-sized tissue sections. However, when the abnormal tissue had avisible lesion, radiologists seemed to rely on additional mech-anisms beyond the texture descriptions; performance increasedfor the real tissue sections. These findings suggest that radiol-ogists can use texture descriptions as global signals of abnor-mality in interpretation of breast tissue.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"texture analysis"},{"word":"medical image perception"},{"word":"visual search"},{"word":"ROC curves"},{"word":"log likelihood ratios"}],"section":"Publication-based-Talks","is_remote":true,"remote_url":"https://escholarship.org/uc/item/1hx386sk","frozenauthors":[{"first_name":"Yelda","middle_name":"","last_name":"Semizer","name_suffix":"","institution":"Rutgers","department":""},{"first_name":"Melchi","middle_name":"M","last_name":"Michel","name_suffix":"","institution":"Rutgers","department":""},{"first_name":"Karla","middle_name":"K","last_name":"Evans","name_suffix":"","institution":"University of York","department":""},{"first_name":"Jeremy","middle_name":"M","last_name":"Wolfe","name_suffix":"","institution":"Harvard","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2018-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/27887/galley/17525/download/"}]}
