摘　　要：目的探究数字化连续性断层融合（Tomosynthesis,TOMOS）技术在乳腺癌诊断中的应用价值。方法对经手术病理证实的34例乳腺癌患者的数字化X线钼靶图像与TOMOS图像进行回顾性对比分析，并与病理进行对照研究。结果34例肿块型乳腺癌在采用扫描基础条件为：65-70kV，1.4-2.0mAs进行扫描，2mm层厚进行TOMOS成像的乳腺图像上均能很好显示。结论断层融合术能更清楚显示乳腺肿块同时显著降低X线投照剂量。Objective To assess the application value of tomosynthesis （TOMOS） technology in the diagnosis for breast cancer. Methods The mammographic images and the TOMOS images of 34 patients with breast cancer confirmed by pathology are retrospectively and comparatively analyzed, and performed control study with pathology. Results The basic scanning conditions are： 65-70kV, 1.4-2.0 mAs, digital continuous fault fusion imaging with 2 mm seam thickness, 34 cases of massive type of breast cancer are displayed well. Conclusion TOMOS can show a breast lump more clearly, in the meantime, TOMOS could reduce X-ray dose significantly.
