目的:运用彩色多普勒(简称彩超)和乳腺血氧功能成像系统(简称血氧三算子)诊断乳腺良恶性病变,评价两种检查手段单独及联合使用的敏感性、准确性、特异性及恶性病变的漏诊率。方法:对214例住院需手术患者术前行彩超和血氧三算子检查,判断良、恶性及与术后病理符合率。结果:在敏感性方面血氧三算子与彩超有差异,但无统计学差异(χ2=1.67,P>0.05),准确性方面二者有统计学差异(χ2=3.91,P<0.05),特异性方面无统计学差异(χ2=0.41,P>0.05),恶性病变漏诊率血氧三算子与彩超分别为11.67%和20.34%,两者相比差异无统计学意义(χ2=1.66,P>0.05);两者联合后恶性病变漏诊率由单一手段的最低11.67%下降至3.33%。结论:血氧三算子检查对诊断乳腺良恶性疾病具有较高敏感性、准确性、特异性及降低恶性漏诊率,联合彩超诊断能降低恶性病变的漏诊率。
Objective: To evaluate benign and malignant breast lesions by color Doppler ultrasonography and breast oximetry imaging system (referred to as oximetry three operators), and to evaluate the sensitivity, accuracy and specificity of the two methods of examination alone and in combination And the rate of misdiagnosis of malignant lesions. Methods: Two hundred and fourteen patients undergoing surgery underwent preoperative color Doppler echocardiography and oximetry triple operator examination to determine the benign, malignant and postoperative pathological coincidence rates. Results: In terms of sensitivity, there were significant differences between the three oximeters and the color Doppler ultrasound, but there was no significant difference (χ2 = 1.67, P> 0.05) There was no significant difference in the specificity (χ2 = 0.41, P> 0.05). The rate of misdiagnosis rate of malignant lesions was 11.67% and 20.34% respectively, there was no significant difference between the two methods (χ2 = 1.66, P> 0.05). The rate of misdiagnosis of combined malignant lesions decreased from the lowest of 11.67% to 3.33%. Conclusion: The oximetry triple operator test is highly sensitive, accurate and specific for the diagnosis of benign and malignant breast diseases. The combined diagnosis of ultrasound and ultrasonography can reduce the misdiagnosis rate of malignant lesions.
