目的:通过分析乳腺肿瘤的钼靶X线表现特征,提高乳腺肿瘤的术前诊断水平,以提高其术前指导价值。材料与方法:对经术后病理检查证实的140例乳腺肿瘤全数字化钼靶X线表现特征进行对照分析,其中恶性94例,良性46例。结果:良恶性肿瘤X线诊断准确率分别为86·34%和90·56%。X线诊断的敏感性、特异性、准确性分别为96·34%,91·45%和95·21%,阳性预测值96·03%,阴性预测值91·04%。毛刺状肿块、细微簇样钙化是乳腺恶性肿瘤特异性X线征象。结论:乳腺钼靶摄影是鉴别良恶性肿瘤的有效影像学方法。
OBJECTIVE: To improve the preoperative diagnosis of breast tumors by analyzing the mammographic characteristics of breast tumors and to improve the preoperative guidance value. MATERIALS AND METHODS: A total of 140 cases of breast tumors confirmed by postoperative pathology were analyzed for mammographic X-ray findings. Among them, 94 were malignant and 46 were benign. Results: The diagnostic accuracy rates of benign and malignant tumors were 86.34% and 90.56% respectively. The sensitivity, specificity and accuracy of X-ray diagnosis were 96.34%, 91.45% and 95.21% respectively, the positive predictive value was 96.03% and the negative predictive value was 91.04%. Burr-like tumor, subtle cluster-like calcification of breast cancer-specific X-ray signs. Conclusion: Breast mammography is an effective imaging method for differentiating benign and malignant tumors.
