乳腺良恶性病变的钼靶X线征象与病理特征

Clinicopathologic characteristics of mammographic features for benign and malignant breast tumors

目的:评价钼靶X线检查对乳腺良恶性病变的诊断价值,初步探讨其病理特征。方法:对96例乳腺病变患者进行X线钼靶检查,分析比较病变的边缘特征、钙化等征象,并与病理结果进行对照。结果:96例患者中术前钼靶X线诊断为乳腺癌40例,良性病变56例。经病理证实乳腺癌42例,良性病变54例。钼靶X线正确诊断90例,正确诊断率为93.75%。分析X线钼靶检查结果与手术病理结果一致性较好,乳腺良恶性病变肿块边缘特征的差异有显著性(P<0.01)。结论:X线钼靶检查是诊断乳腺病变的有效手段,良恶性病变在肿块边缘、钙化等方面具有不同的影像学特征,不同征象是以不同的病理为基础的。

Objective To evaluate the diagnostic value of X-ray for benign and malignant breast tumors and analyze the correlation between the mammography and pathologic findings. Methods Ninety-six patients with breast tumors receiving mammographic examination were analyzed the characteristics of the border, calcification, etc, and compared with pathologic features. Results Ninety-six cases were proved by pathology including 42 cases of breast carcinoma, 54 cases of benign pathologic changes. Ninety cases were diagnosed correctly with mammography, with an accuracy of 93.75%. The coincidence between mammography and pathology was satisfactory. There was a significant difference in X-ray features of border between breast carcinoma and benign pathologic changes（P〈0.01）. Conclusion X-ray features of irregular border, micro-calcification are useful in differentiating carcinoma from benign tumors. All these characters are based on the clinicopathologic features of the disease.
