US和MTM评估不同类型乳腺微小肿块的价值研究

Study on the Value of US and MTM in Evaluating Different Types of Breast Micromass

目的:对比分析在不同类型乳腺微小肿块鉴别诊断中,超声(Ultrasonic,US)、钼靶X射线乳腺摄影(Molybdenum target mammography,MTM)的应用效果。方法:研究病例均来自本院收治的乳腺肿块患者,均以病理学检查明确诊断,其中良性组及恶性组各120例。对两组患者的术前US、MTM资料进行回顾性分析,对比乳腺良性肿块与恶性肿块的影像学特征,以病理学作为诊断金标准,并计算相关诊断学指标。结果:恶性组在US检查后,在影像特征上与良性组有显著差异(P<0.05);恶性组经MTM检查后,在影像特征上与良性组有显著差异(P<0.05);良性组透亮环特征检出率高于恶性组;US及MTM、US+MTM对乳腺微小肿块的诊断价值中,灵敏度分别为81.67%、85.00%、93.33%,特异度分别为86.67%、78.33%、90.83%;US+MTM的价值更高(P<0.05)。结论:乳腺微小肿块诊断中,US及MTM都能够发挥其各自的价值,但相对来说,联合诊断的价值相比单独诊断方式,更具疾病鉴别诊断价值。

Objective:To compare and analyze the application effects of ultrasound(US)and molybdenum target X-ray mammography(MTM)in the differential diagnosis of different types of small breast masses.Methods:A study was conducted on cases of breast masses admitted to our hospital,all of which were diagnosed through pathological examination.There were 120 cases in each of the benign and malignant groups.Retrospective analysis of preoperative US and MTM data of two groups of patients,comparing the imaging characteristics of benign and malignant breast masses,using pathology as the diagnostic gold standard,and calculating relevant diagnostic indicators.Results:After US examination,there was a significant difference in imaging features between the malignant group and the benign group(P<0.05);After MTM examination,there was a significant difference in imaging features between the malignant group and the benign group(P<0.05);The detection rate of transparent ring in benign group was higher than that in malignant group(P<0.05);In the diagnostic value of US and MTM,US+MTM for small breast masses,sensitivity:81.67%,85.00%,93.33%,specificity:86.67%,78.33%,90.83%;The value of US+MTM is higher(P<0.05).Conclusion:In the diagnosis of small breast masses,both US and MTM can play their respective roles,but relatively speaking,the value of combined diagnosis is more valuable in disease differentiation than individual diagnosis.
