摘　　要：目的探讨常规超声对乳腺X线表现为单纯微钙化病灶的检出率及影响因素,并比较两种检查方法对乳腺癌的诊断价值。方法收集2013年1月~2017年9月乳腺X线诊断为乳腺微钙化病灶的患者79例共81个病灶,以病理诊断为金标准,回顾性研究常规超声对乳腺微钙化病灶的检出率及影响因素,同时比较分析常规超声与乳腺X线的诊断价值。结果常规超声对乳腺微钙化病灶的检出率为79.01%,对恶性病灶的检出率高于良性病灶(93.18%vs 62.16%),差异有统计学意义(P<0.05),不同病灶大小、钙化分布、钙化形态之间的检出率对比,差异无统计学意义(P>0.05)。常规超声和乳腺X线对乳腺癌的诊断敏感性、特异性、准确性分别为77.27%、97.30%、86.42%和84.09%、86.49%、85.19%,差异无统计学意义(P>0.05)。常规超声和乳腺X线的受试者工作特征曲线下面积差异无统计学意义(P>0.05)。结论常规超声对乳腺X线表现为单纯微钙化的病灶有较高的检出率,其中恶性病灶明显高于良性病灶;常规超声对微钙化乳腺癌的诊断价值与乳腺X线相仿。Objective To investigate the detection rate and influencing factors of simple microcalcification lesions in breast X ray by conventional ultrasound,and to compare the diagnostic value of the two methods in breast cancer. Methods From January 2013 to September 2017,a total of 81 breast microcalcification lesions were diagnosed by breast X ray in 79 patients.The detection rate and influencing factors of microcalcified breast lesions by conventional ultrasound were studied retrospectively according to the gold standard of pathological diagnosis.At the same time,the diagnostic value of conventional ultrasound and breast X ray was compared and analyzed.Results The detection rate of breast microcalcification lesions by conventional ultrasound was 79.01%,and the detection rate of malignant lesions was higher than that of benign lesions（93.18%vs62.16%）,the difference was statistically significant（ P〈0.05）.There was no significant difference in the detection rate of different lesion size,calcification distribution and calcification morphology（P〉0.05）.The sensitivity,specificity and accuracy of conventional ultrasound and breast X ray in the diagnosis of breast cancer were77.27%,97.30%,86.42%,and 84.09%,86.49%,and 85.19%,respectively,there was no statistically significant difference（ P〉0.05）.The area under the receiver operating characteristic curve of conventional ultrasound and breast X ray was not statistically different（ P〉0.05）.Conclusion Conventional ultrasound has a high detection rate for the lesions of simple microcalcification,among which malignant lesions are significantly higher than those of benign lesions,and the diagnostic value of conventional ultrasound for microcalcification of breast cancer is similar to that of breast X ray.
