彩色多普勒超声诊断小乳腺癌与乳腺增生的临床价值

Clinical value of color Doppler ultrasonography in diagnosis of small breast cancer and hyperplasia of mammary gland

目的探讨彩色多普勒超声诊断小乳腺癌与乳腺增生的临床价值。方法选取2015年1月至2020年12月本院收治的102例乳腺疾病患者作为研究对象,入院后均行彩色多普勒超声检查,根据病理检查结果分为乳腺增生组(n=60)和小乳腺癌组(n=42),比较两组血流分级、多普勒图像、阻力指数(RI)及收缩期峰值流速(SPV)。结果小乳腺癌组病灶不规则、边界蟹足样及内部回声不均匀占比均高于乳腺增生组(P<0.05);小乳腺癌组RI高于乳腺增生组,PSV水平快于乳腺增生组,差异有统计学意义(P<0.05);两组血流分级比较差异有统计学意义(P<0.05)。结论彩色多普勒超声可根据血流信号和病灶形态鉴别诊断小乳腺癌与乳腺增生,有助于减少漏诊或误诊,值得临床推广应用。

Objective To investigate the clinical value of color Doppler ultrasound in the diagnosis of small breast cancer and breast hyperplasia.Methods 102 patients with breast diseases admitted to our hospital from January 2015 to December 2020 were selected as the study subjects.After admission,all patients underwent color Doppler ultrasound examination,they were divided into breast hyperplasia group(n=60)and small breast cancer group(n=42)according to the pathological examination results.The blood flow grading,Doppler image,resistance index(RI)and spectral contraction peak flow rate(SPV)were compared between the two groups.Results The proportion of irregular lesion,boundary crab foot shape and uneven internal echo in small breast cancer group was higher than that in breast hyperplasia group(P<0.05),the RI in the small breast cancer group was higher than that in the hyperplasia group,and the PSV was faster than that in the hyperplasia group,and the differences were statistically significant(P<0.05).There was statistically significant difference in blood flow grading between the two groups(P<0.05).Conclusion Color Doppler ultrasound can distinguish small breast cancer from breast hyperplasia according to blood flow signal and lesion morphology,which is helpful to reduce missed diagnosis or misdiagnosis,and worthy of clinical application.
