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 analyze and compare the clinical diagnostic value of SonoCT high-frequency ultrasound imaging and mammography X-ray radiography in the diagnosis of breast masses. Methods A total of 193 patients with breast masses, including 58 breast cancers and 135 benign tumors, underwent SonoCT high-frequency ultrasonography and mammography at the same time before surgery. Results Ultrasonography diagnosed 46 cases of early breast cancer with a sensitivity of 79 31%, a specificity of 94 81%, and an accuracy of 90 16%. The molybdenum target diagnosed early-stage breast cancer in 47 cases with a sensitivity and specificity of 81 0 3% and 89.63%, and an accuracy of 87 0 5 %. Ultrasound has higher sensitivity, specificity and accuracy for benign tumor classification than molybdenum target. Conclusion SonoCT high-frequency ultrasound is compared with mammography. It is found that the sensitivity and negative predictive value of the former is closer to the latter than that of the latter, and the specificity and positive predictive value are higher than that of the latter. The former is better than the latter.
