目的 总结乳腺钼靶显示的细小钙化对于乳腺癌诊断的临床价值.方法 选取在我院收治的在乳腺钼靶摄片中发现钙化并经病理证实的患者65例,剖析钙化的形态、数目、大小、分布、密度情况.结果 钼靶显示有钙化现象的良恶性患者分别为:良性钙化者34例,恶性钙化者31例.乳腺恶性钙化主要表现为形状不一致,大小不均等、密度不均匀,成簇状分布,区段性分布也可以是沿导管走行区域分布.乳腺良性钙化主要表现为颗粒状,形态粗,边界清楚,散在分布.结论 总结乳腺恶性钙化的特点,有利于鉴别乳腺良恶性病变,对于提高乳腺癌诊断符合率有重要的临床价值.“,”Objective To analyze the the imaging features of tiny breast calcification in the Molybdenum target X-ray film,to evaluate its clinical significance in the Breast cancer diagnosis.A contrastive analysis was conducted on the patients in two groups with shape,distribution,size,density and calcification quantity,compared with the pathological results.Results Tiny calcification could appear on patients with breast benign lesion or malignant lesion.The amount of malignant lesion patients was 38,while the benign lesion patients was 29.The imaging features of malignant lesion calcification mainly manifested as different form,inequality of size,unevendensity,clusterdistribution,regional distribution or distribution along the conduit while benign lesion calcification mainly manifested as coarser particles,sharpness of border,and widely scattered.Conclusion The imaging features of tiny breast calcification can be the reliable basis in identifying benign and malignant breast lesion,and is of great significance for the diagnosis of breast cancer.
