乳腺黏液腺癌与纤维腺瘤的MRI鉴别诊断分析
MRI differentiation between breast mucinous carcinoma and fibroadenoma
摘要
Abstract
Objective: To explore the MRI differentiation between breast mucinous carcinoma (MCs) and fibroadenoma (FAs) as to improve the diagnostic accuracy of MCs of the breast.Materials and Methods: 31 cases of breast MCs and 50 cases of FAs confirmed by pathology were collected. Results: Breast MCs and FAs T2 WI all showed higher signal intensity on T2 WI. ①Morphology: irregular margins were observed more frequently in MCs, but FAs showed more margin circumscribed. ②ADC value: the mean ADC value of pure-MCs was (1.8±0.5) ×10-3 mm2/s, the mean ADC value of mixed-MCs was (1.0±0.6) ×10-3 mm2/s, the mean ADC value of FAs was (1.4±0.30) ×10-3 mm2/s. ③Internal enhancement characteristic:pure-MCs also showed delayed heterogeneous enhancement (45%, 9/20) and rim enhancement (45%, 9/20), mixed-MCs also showed heterogeneous enhancement (91%, 10/11), FAs showed homogeneous enhancement (44%, 22/50) and heterogeneous enhancement (40%, 20/50) and dark internal septation (14%, 7/50). ④Time signal intensity curve (TIC) : pure-MCs and FAs also showed Ⅰ type, mixed-MCs also showed Ⅲ type. The difference of MCs and FAs was statistically significant (P<0.05). Conclusions: Breast MCs and FAs are relatively characteristic in MRI. Correctly understanding the characteristics of MRI can improve the diagnostic accuracy of MCs.关键词
