【摘要】 目的:初步探讨在乳腺癌X线诊断中,辅助应用CAD系统的临床应用效果。方法:将本院自1999～2002年467例经手术病理证实的乳腺癌并具X线检查的病例,分别使用放射科医师独立诊断和其辅助应用CAD系统(激光扫描法)诊断,统计各自诊断发现肿块及微钙化的敏感性,并进行对比研究。结果:放射科医师独立诊断乳腺癌敏感性为80.94％,辅助CAD诊断敏感性为88.01％,其中对肿块检测敏感性分别为81.42％,89.38％;对微钙化检测敏感性分别为80.70％,94.74％。结论:放射科医师辅助CAD的应用使钼靶诊断乳腺癌检出率有一定的提高,尤其对于微钙化病灶。更多还原

【Abstract】 Purpose: To determine breast carcinoma detection rate of a new mammographic computer-aided system (CAD) in order to assess its clinical usefulness. Methods: 467 cases of breast carcinoma proved by surgery and pathology were retrospectively analyzed. All the mammograms of the cases were reviewed by two radiologists working as a team and then analyzed by the CAD-system. The sensitivity for breast carcinoma detection (masses or calcification) was calculated respectively, and the results compared. Results: The sensitivity for breast carcinoma detection by the same radiologists without and with the CAD-system were 80. 94% , 88. 01% , respectively (P<0. 05). For masses, the sensitively were 81. 42%, 89. 38%, respectively and for calcifications were 80. 70% and 94. 74%. Conclusions: The CAD system is an emerging technology for improving the mammographic detection of breast cancer, especially for micro-calcifications.更多还原
