【摘要】：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(P0.05)。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。
[Abstract]:Objective to compare the imaging findings of breast fibroadenoma with Mr imaging (MRI) and its diagnostic value. Methods 100 patients with breast fibroadenoma confirmed by pathology from February 2013 to February 2016 were studied. All patients were examined with MRI before operation and their imaging findings were observed. To compare the diagnostic coincidence rate of ultrasonography and MRI in breast fibroadenoma. Results: there were 118 mammary fibroadenoma confirmed by pathology, 93 round shape, 86 capsular echo, 76 homogeneous echo and 28 calcification. Blood flow signal 0 grade 60 / 1 grade 50 MRI showed round shape, round shape 96, edge clear 90 / T 1WI 108 / T 2WI high signal 94, homogeneous enhancement 78, inhomogeneous enhancement 19 / TIC type I 93 (78.81%). The diagnostic coincidence rate of ultrasound in breast fibroadenoma was 90.00% significantly lower than that of MRI 98.00. The difference was statistically significant (P 0.05). Conclusion Ultrasound MRI is helpful to the diagnosis of breast fibroadenoma by typical imaging signs, and MRI is more advantageous than ultrasound in the diagnosis of breast fibroadenoma.
