目的 分析超声联合CT在乳腺癌 肿块性质鉴别中的应用价值。方法 回 顾性分析我院2011年6月-2015年5月收 治的68例乳腺肿块患者的超声及CT影像 学资料，比较CT、超声及其联合诊断乳 腺肿块的准确率，分析其在良恶性乳 腺肿块中的鉴别价值。结果 超声检出 良性肿块18例(78.26%)，恶性肿块39 例(86.67%)，整体符合率为83.82%； CT检出良性肿块20例(86.96%)，恶性 肿块39例(93.33%)，整体符合率为 91.18%；两者联合诊断检出良性肿块22 例(95.65%)，恶性肿块43例(95.56%)， 整体符合率为95.59%；联合诊断与病理 符合度高，与单用超声检查对比差异有 统计学意义(P＜0.05)。结论 采用超声 联合CT诊断乳腺病变与病理符合度高， 良恶性鉴别价值高，对触诊阴性，超声 检出可疑恶性病变者需结合CT检查作辅 助筛查，可提高检出率。

Objective To analyze the application value of ultrasound combined with CT in the identifying the nature of breast lumps. Methods The ultrasound and CT imaging data of 68 patients with breast lumps who were admitted into our hospital between June 2011 and May 2015 were retrospectively analyzed. The accuracy rates of CT, ultrasound and the combination in the diagnosis of breast lumps were compared. The value of them in the differential diagnosis of benign and malignant breast lumps was analyzed. Results 18 cases (78.26%) of benign lumps and 39 cases (86.67%) of malignant ones were detected by ultrasound and the overall coincidence rate was 83.82%, 20 cases (86.96%) of benign lumps and 39 cases (93.33%) of malignant ones were detected by CT and the overall incidence rate was 91.18%, 22 cases (95.65%) of benign lumps and 43 cases (95.56%) of malignant ones were detected by the combined diagnosis and the overall coincidence rate was 95.59%, There was a high degree of coincidence between the combined diagnosis and pathology. Compared with ultrasound single diagnosis, the difference was statistically significant (P<0.05). Conclusion Ultrasound combined with CT in diagnosis of breast lesions is of high coincidence with pathology. The value of differential diagnosis of benign and malignant lumps is high. For nonpalpable lesions, ultrasound in diagnosis of suspected malignant lesions should be combined with CT for auxiliary screening, which can improve the detection rate.
