目的 分析比较乳腺纤维腺瘤的 超声、磁共振成像（MRI）影像表现及其 诊断价值。方法 以2013年2月～2016年 2月经病理证实的100例乳腺纤维腺瘤患 者为研究对象，术前均接受超声、MRI检 查，观察各自影像学表现，并以术后病理 结果为金标准，比较超声、MRI对乳腺纤 维腺瘤的诊断符合率。结果 影像表现： 术后病理证实乳腺纤维腺瘤共118枚，超 声显示圆形、类圆形形态93枚，包膜样 回声86枚，内部均匀回声76枚，伴钙化 28枚，血流信号0级60枚，1级50枚；MRI 显示圆形、类圆形形态96枚，边缘清晰 90枚，T1WI等信号108枚，T2WI高信号94 枚，均匀强化78枚，不均匀强化19枚， TIC分型：I型93枚，占78.81%。超声对乳 腺纤维腺瘤诊断符合率为90.00%显著低 于MRI的98.00%，差异有统计学意义（P ＜0.05）。结论 超声、MRI通过典型影像 学征象显示有助于乳腺纤维腺瘤诊断，其 中MRI相比超声诊断乳腺纤维腺瘤更有优 势。

Objective To analyze the findings and diagnostic value of ultrasound and magnetic resonance imaging (MRI) for breast fibroadenoma. Methods One hundred patients with pathologically confirmed breast fibroadenoma between February 2013 and February 2016 were selected as the study subjects. Before operation, all subjects underwent ultrasound and MRI examination. The respective imaging findings were observed. With postoperative pathological results as the golden standard, the coincidence rate was compared between ultrasound and MRI in the diagnosis of breast fibroadenoma. Results The imaging findings showed that there were a total of 118 pathologically confirmed breast fibroadenomas. Ultrasound showed that 93 were round or quasi-circular, 86 with capsule like echo, 76 with internally homogeneous echo, 28 with calcification, 60 with grade 0 blood flow signal and 501 with grade 1, MRI show that 96 were round or quasicircular, 90 with clear edges, 108 with equal signal on T1WI, 94 with high signal on T2WI, 78 with homogeneous enhancement and 19 with inhomogeneous enhancement. TIC typing showed 93 of type I, accounting for 78.81%. The coincidence rate of ultrasound in the diagnosis of breast fibroadenoma (90.00%) was significantly lower than that of MRI (98.00%) (P<0.05). Conclusion The typical imaging findings of ultrasound and MRI can help the diagnosis of breast fibroadenoma. Compared with ultrasound, MRI has more advantages in the diagnosis of breast fibroadenoma.
