彩超对乳腺肿瘤血流频谱及形态学的分析

Analysis of color doppler ultrasound for blood flow spectrum and morphology of breast tumor

目的:探讨彩色多普勒诊断乳腺肿瘤血流频谱及形态学参数,总结乳腺癌早期诊断的价值。方法:收治超声检查乳腺肿块有血流患者160例,采用GELogiq9型彩色多普勒超声仪进行检查,分析检查结果。结果:病理诊断结果乳腺恶性肿瘤25例,乳腺增生3例,乳腺纤维腺瘤132例。超声学诊断乳腺恶性肿瘤24例,诊断符合率96.0%;乳腺增生3例,诊断符合率100.0%。乳腺纤维腺瘤133例,1例恶性肿瘤误诊为乳腺纤维腺瘤。乳腺增生、乳腺纤维腺瘤之间Vmax和RI比较差异无统计学意义(P>0.05),但与乳腺癌比较差异有统计学意义(P<0.05)。结论:彩超诊断乳腺肿块具有无创、重复性好,误差率低等优点,收缩期流速(Vmax)、阻力指数(RI)是区分良性和恶性的重要指标,对辨别恶性和良性肿瘤有重要临床意义。

Objective:To explore the blood flow spectrum and morphological parameters of color doppler ultrasound in diagnosing breast tumors,to summarize the value of early diagnosis of breast cancer.Methods:160 cases of breast masses with blood flow were selected examined by ultrasonography,we analyzed the results.Results:In pathological diagnosis,there were 25 cases of breast malignancy,3 cases of hyperplasia of mammary glands and 132 cases of fibroadenoma of breast.In the ultrasonographic diagnosis,there were 24 cases of breast malignant tumors,the diagnostic coincidence rate was 96.0%,there were 3 cases of breast hyperplasia,the diagnostic coincidence rate was 100.0%.there were 133 cases of fibroadenoma of breast,1 case of malignant tumor was misdiagnosed as fibroadenoma of the breast.There was no significant difference in Vmax and RI between hyperplasia of mammary glands and fibroadenoma of breast(P>0.05),but there was significant difference compared with breast cancer(P<0.05).Conclusion:Color doppler ultrasound had the advantages of non-invasive,good repeatability and low error rate in the diagnosis of breast masses,systolic velocity of flow(Vmax)and resistance index(RI)were important indices to distinguish benign from malignant tumors,and had important clinical significance to distinguish malignant from benign tumors.
