ABSTRACT
Objective To evaluate the using and results of computer-aided detection for full-field digital mammography in Chinese women. Methods 934 individuals more than 40 years old from a specific unit in Shenyang city were screened by full-field digital mammography ( Senographe 2000D, GE) . The examination images were diagnosed firstly by the experienced radiologists and then were analyzed by the computer-aided detection system ( R2' Image Checker ) , respectively. The results from these two assays were compared. Results The prompts were generated in 799 out of 1734 normal images, false-positive rate of computer-aided detection ( CAD) was 46. 1 % in the cases with normal breast image. The correct prompts rate was 70. 5 % in the cases with breast mass, 75. 0 % in the cases with breast microcalcification and 100. 0 % in the cases with breast cancer. Conclusion Although the CAD system has showed clinical values in practice, there are still some false-positive and false-negative results.
