目的:探讨超声弹性成像联合X线钼靶摄影对乳腺肿瘤的诊断价值。方法:回顾性分析经病理证实的乳腺肿瘤患者310例共320个病灶。比较3种方法与病理对乳腺肿瘤的诊断结果和诊断性能。结果:超声弹性成像联合X线钼靶摄影与病理诊断间差异无统计学意义(P>0.05),Kappa系数为0.926。联合超声弹性成像和X线钼靶摄影的准确性、特异性和阳性预测值明显高于单独应用超声弹性成像或X线钼靶摄影检查,差异有统计学意义,均P<0.01。结论:超声弹性成像和X线钼靶摄影诊断乳腺肿瘤各有其优劣势,联合两种影像检查有助于乳腺肿瘤良恶性的鉴别诊断。
Objective: To investigate the diagnostic value of ultrasound elastography combined with mammography in the diagnosis of breast tumors. Methods: A total of 320 lesions of 310 patients with pathologically confirmed breast tumors were retrospectively analyzed. Comparison of 3 methods and pathology of breast cancer diagnosis and diagnostic performance. Results: There was no significant difference between ultrasound elastography and X-ray mammography and pathological diagnosis (P> 0.05). The Kappa coefficient was 0.926. The accuracy, specificity and positive predictive value of combined ultrasound elastography and X-ray mammography were significantly higher than that of ultrasound elastography alone or mammography. The difference was statistically significant, both P <0.01. Conclusion: Ultrasound elastography and mammography in the diagnosis of breast cancer have their own advantages and disadvantages, combined with the two imaging examination is helpful in the differential diagnosis of benign and malignant breast tumors.
