超声S-Detect技术在乳腺肿块诊断中的价值

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。

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

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 moderatelyexperienced and senior physicians (P>0.05). S-Detect technique was positively correlated with the diagnostic results of seniorphysicians (r=0.97). Using S-Detect technique, the diagnostic efficacy did not differ significantly between the long axis sectionand its vertical section (P>0.05). Routine ultrasound showed a better diagnostic efficacy than S-Detect for breast masses with adiameter 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.
