常规超声对乳腺X线单纯微钙化病灶的诊断价值(1)
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。

Abstract：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 were 77.27%，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.

乳腺癌(breast cancer)是我國发病率最高的女性恶性肿瘤，也是我国女性首位癌症死亡原因[1]。微钙化是乳腺癌影像学诊断的重要指标，或是早期乳腺癌的唯一征象。随着超声医学的发展，超声的分辨力也越来越高，7～12 MHz的线阵探头在人体软组织中的理论轴向分辨力为0.065～0.11 mm[2]，而乳腺可疑钙化点直径多在5 mm以下[3]，因此理论上超声对乳腺微钙化应有较高的显示率。乳腺X线检出乳腺钙化灶的价值已得到广泛认可，但超声对乳腺X线表现为单纯微钙化乳腺病灶的研究却鲜有报道，本文即针对该类患者展开研究，探讨常规超声对此类病灶的检出率及诊断价值。, http://www.100md.com(王文平 吕小勇)
