摘　　要：目的探讨彩色多普勒血流显像(CDFI)联合磁共振成像(MRI)对乳腺纤维腺瘤(FA)和乳腺小体积叶状肿瘤(sPTB)的鉴别诊断价值。方法回顾性分析2017年1月至2018年12月我院54例乳腺肿瘤患者的临床资料,按照手术病理检查结果将42例确诊FA者纳入FA组,将12例确诊sPTB者纳入sPTB组。分析两组CDFI、MRI表现。结果FA组高频声像图典型表现为肿块形态规则,边界清晰,包膜光整,内部回声较低、均匀,后方回声增强,与sPTB组高频声像图特征差异有统计学意义(P<0.05)。FA组CFDI血流信号分级多为0、Ⅰ级,乳腺癌则多为Ⅱ、Ⅲ级,与sPTB组相比差异有统计学意义(P<0.05)。FA组血流收缩期峰值流速(PSV)和阻力指数(RI)均小于sPTB组(P<0.05)。FA组与sPTB组在MRI扫描下,肿瘤分叶形态、平扫信号、强化特点、囊腔产生情况、血管增多情况差异均有统计学意义(P<0.05)。结合病理结果,CDFI联合MRI诊断FA和sPTB的准确率分别为90.48%、83.33%。结论CDFI、MRI在FA、sPTB检查中表现特征显著,二者联合应用对FA、sPTB鉴别诊断价值显著。Objective To explore the differential diagnostic value of color Doppler flow imaging(CDFI)combined with magnetic resonance imaging(MRI)on breast fibroadenoma(FA)and small-volume phyllode tumor of breast(sPTB).Methods The clinical data of 54 patients with breast tumors in the hospital between January 2017 and December 2018 were retrospectively analyzed.According to the results of surgical pathology,42 patients with confirmed FA were included in FA group and 12 patients with confirmed sPTB were enrolled as sPTB group.The CDFI and MRI findings were analyzed in the two groups.Results Typical findings of high frequency ultrasonography in FA group showed regular mass shape,clear boundary,smooth envelope,low and uniform internal echo and rear echo enhancement,and there were statistically significant differences compared with features of high frequency ultrasonography in sPTB group(P<0.05).The grades of CFDI blood flow signals of FA group were mostly grade 0 and gradeⅠand those of breast cancer were gradeⅡand gradeⅢ,which were statistically different from those of sPTB group(P<0.05).The peak flow velocity(PSV)at systolic phase and resistance index(RI)of FA group were smaller than those of sPTB group(P<0.05).Combined with pathological results,the accuracy rates of CDFI combined with MRI in the diagnosis of FA and s PTB were 90.48%and 83.33%respectively.Conclusion CDFI and MRI have significant features in the examination of FA and sPTB,and the combined application of the two has a significant value in the differential diagnosis of FA and sPTB.
