乳腺肿块SonoCT高频超声显像与钼靶X线诊断对照研究

Controlled Study of Sono CT High Frequency Ultrasonography with Mammography in Diagnosis of Breast Tumor

目的 分析比较SonoCT高频超声显像与钼靶X线摄影法对乳腺肿块的临床诊断价值。 方法 193例乳腺肿块患者 ,其中乳腺癌 5 8例 ,良性肿块 135例 ,在术前 1周内同时行SonoCT高频超声显像和钼靶X线摄影检查。 结果 超声诊断早期乳腺癌 46例 ,其敏感性 79 31%,特异性 94 81%,准确性 90 16 %。钼靶诊断早期乳腺癌 47例 ,其敏感性和特异性为81 0 3%和 89 6 3%,准确性为 87 0 5 %。超声对于良性肿瘤分类诊断的敏感性、特异性和准确性均高于钼靶。 结论 SonoCT高频超声与钼靶X线摄影比较 ,发现前者对早期乳腺癌的敏感性和阴性预测值近于后者 ,特异性和阳性预测值则高于后者 ,而对于良性肿瘤的分类诊断前者优于后者。

Objective To evaluate Sono CT high frequency ultrasonography and mammography in the diagnosis of breast tumor Methods Sono CT high frequency ultrasonography and mammography were performed within one week for 193 patients with breast neoplasms,among them breast cancer was in 58,benign lesions in 135,all proved pathologically.Results Ultrasonography demonstrated breast cancer in 46 cases,the sensitivity and specificity were 79.31% and 94.81% respectively,with the accuracy of 90.16% while mammography revealed breast cancer in 47 cases.The sensitivity and specificity were 81.03% and 89.63%,respectively,with the accuracy of 87.05%.Conclusion Comparing Sono CT high frequency ultrasonography with mammography the sensitivity and negative predictive value in demonstrated breast cancer of the former are similar to those of the latter,while the specificity and the positive predictive value are higher than those of the latter.As to the classified diagnosis for the benign lesions,the former is better than the latter.Both have their own advantages in the diagnosis of breast tumor.
