超声S-Detect技术在乳腺肿块诊断中的价值

Value of ultrasonic S-Detect technique in diagnosis of breast masses

目的探讨超声S-Detect技术在乳腺肿块病灶诊断中的应用价值。方法采用S-Detect技术及常规超声对62例女性患者总计85个乳腺肿块进行诊断,以术后病理结果为金标准,对比分析常规超声与S-Detect技术的诊断效能。结果低年资医师常规超声诊断效能低于S-Detect技术(P<0.05),中年资、高年资医师常规超声诊断效能与S-Detect技术无显著差异(P>0.05)。S-Detect技术与高年资医师诊断结果呈正相关(r=0.97)。S-Detect技术长轴切面和长轴垂直切面的诊断效能无显著差异(P>0.05)。中年资医师常规超声诊断直径≤20 mm乳腺肿块的效能优于S-Detect技术(P<0.05),但诊断直径>20 mm乳腺肿块的效能低于S-Detect技术(P<0.05)。结论S-Detect技术可用于乳腺良恶性肿块的鉴别诊断,其诊断效能可达到中、高年资医师BI-RADS分类的诊断水平,但在诊断直径不足20mm乳腺肿块时的效能并不十分理想。

Objective To evaluate the value of ultrasound S-Detect in the diagnosis of breast masses.Methods A total of 85 breast masses in 62 female patients were diagnosed by S-Detect technique and conventional ultrasound.The diagnostic efficacy of conventional ultrasound and S-Detect technique was analyzed and compared with postoperative pathological results as the gold standard.Results When operated by junior physicians,the diagnostic efficacy of conventional ultrasound was significantly lower than that of S-Detect technique(P<0.05),but this difference was not observed in moderately experienced and senior physicians(P>0.05).S-Detect technique was positively correlated with the diagnostic results of senior physicians(r=0.97).Using S-Detect technique,the diagnostic efficacy did not differ significantly between the long axis section and its vertical section(P>0.05).Routine ultrasound showed a better diagnostic efficacy than S-Detect for breast masses with a diameter below 20 mm(P<0.05),but for larger breast masses,its diagnostic efficacy was significantly lower than that of S Detect(P<0.05).Conclusion S-Detect can be used in differential diagnosis of benign and malignant breast masses,and its diagnostic efficiency can be comparable with that of BI-RADS classification for moderately experienced and senior physicians,but its diagnostic efficacy can be low for breast masses less than 20 mm in diameter.
