After initial RGI filtering, a sensitivity of 87% at 0.76 false\u2010positive detections per image was obtained on a database of 400 patients (757 images). Next, lesion candidates were segmented from the background by maximizing an average radial gradient (ARD) index for regions grown from the detected points. At an overlap of 0.4 with a radiologist lesion outline, 75% of the lesions were correctly detected. Subsequently, round robin analysis was used to assess the quality of the classification of lesion candidates into actual lesions and false\u2010positives by a Bayesian neural network. The round robin analysis yielded an <jats:inline-graphic xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"graphic\/mp5995-math-0001.png\" xlink:title=\"urn:x-wiley:00942405:media:mp5995:mp5995-math-0001\"\/> value of 0.84, and an overall performance by case of 94% sensitivity at 0.48 false\u2010positives per image. Use of computerized analysis of breast sonograms may ultimately facilitate the use of sonography in breast cancer screening programs.<\/jats:p>","DOI":"10.1118\/1.1485995","type":"journal-article","created":{"date-parts":[[2002,7,28]],"date-time":"2002-07-28T22:21:06Z","timestamp":1027894866000},"page":"1438-1446","source":"Crossref","is-referenced-by-count":190,"title":["Computerized lesion detection on breast ultrasound"],"prefix":"10.1002","volume":"29","author":[{"given":"Karen","family":"Drukker","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maryellen L.","family":"Giger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karla","family":"Horsch","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew A.","family":"Kupinski","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carl J.","family":"Vyborny","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ellen B.","family":"Mendelson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2002,6,20]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.215.1.r00ap151"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2001.19.15.3524"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.155.3.3890010"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.147.3.479"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.151.2.6709920"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9610(00)00459-1"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.196.1.7784555"},{"key":"e_1_2_1_9_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.213.3.r99dc20889"},{"key":"e_1_2_1_10_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.213.2.r99nv13407"},{"key":"e_1_2_1_11_1","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.173.4.10511149"},{"key":"e_1_2_1_12_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.214.1.r00ja2559"},{"key":"e_1_2_1_13_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.213.2.r99nv05413"},{"key":"e_1_2_1_14_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.217.3.r00nv27849"},{"key":"e_1_2_1_15_1","first-page":"831","article-title":"Usefulness of mammography and sonography in women <35 years old","volume":"180","author":"Bassett L.
