摘　　要：目的探讨计算机辅助检测(CAD)对乳腺癌的诊断价值。方法回顾性分析156例乳腺病变患者资料。其中,47例手术患者,34例病理证实为乳腺癌。未手术的病例以X线诊断为标准。分析CAD对乳腺肿块或钙化病变的检出率。结果应用CAD检出单纯肿块104例,单纯钙化42例,10例肿块未检出。CAD对乳腺肿块的检出率为93.6%(146/156),对钙化的检出率100.0%。CAD对乳腺癌的诊断敏感性为91.2%(31/34),准确率为89.4%(42/47)。结论 CAD对乳腺肿块及钙化均有较高的检出率,对乳腺癌具有重要的诊断价值。Objective To investigate the value of computer-aided detection（CAD） system of digital mammography in the diagnosis of breast cancer.Methods Data of 156 patients with breast lesions underwent mammography were analyzed retrospectively,of whom 47 patients were operated with pathology diagnosis of breast cancer in 32 cases.The diagnosis of breast tumor or calcified lesions in the cases without surgery was made by a X-ray physicines using CAD software.Results CAD diagnosed single tumor in 104 cases,single calcified lesions in 42 cases.The diagnosis of breast tumor was missed in 10 cases.The detection rate of mammary mass was 93.6%（146/156） and that of calcification was 100.0%.The sensitivity and accuracy rate of CAD in diagnoding breast cancer were 91.2%（31/34） and 89.4%（42/47） reapectively.Conclusion With a high detection rate for breast mass and calcification,CAD plays an important role in the diagnosis of breast cancer.
