磁共振动态增强对乳腺癌的诊断价值

目的探讨磁共振动态增强（DCE—MRI）对乳腺癌的诊断价值。方法回顾性分析34例初诊为恶性病变者的DCE—MRI表现，观察病灶的形态学特征、强化方式、时间信号强度曲线（TIC）类型，结合BI—RADS分级评分，诊断病变的良、恶性。结果病理证实恶性29例，良性5例。边缘有毛刺或有棘状突起者13例（38．2％），形态不规则11例（32．4％），形态不规则并有毛刺9例（26．5％），边缘光整1例（2．9％）。其中病灶周围血管增粗曲张6例（17．6％）。TIC曲线类型：Ⅰ型O例，Ⅱ型9例（26．5％），Ⅲ型25例（73．5％）。结论DCE—MRI能较好地区分乳腺的良、恶性病灶。

Diagnostic value of dynamic enhancement MRI in breast cancer

Objective To explore the value of dynamic contrast enhancement MRI （DCE - MRI） in the diagnosis of breast carcinoma. Methods Thirty -four patients with primary diagnosis as malignant tumor based on DCE - MRI were analyzed retrospeetively, their morphological features, appearance of DCE -MRI, the type of time- signal intensity curves（ TIC ） were analyzed, combining BIRADS classification rating to make diagnosis between benign and malignant. Results The diagnosis of the 34 patients（29 malignant and 5 benign） were confirmed by pathology. Of the 34 cases, 13 cases （38.2%） showed burrs or spinous process in its boundary, 11 cases （32.4%）showed irregular shape, 9 cases（26.5% ） showed both irregular shape and speculated margin, 1 case （2.9%） showed smooth margin, 6 cases（ 17.6% ） showed disorder and rigidness of the vascular which vascular around lesions. There were 3 types showed on time - signal intensity curve including type Ⅱ 9 cases （ 26.5 % ） , type Ⅲ 25 cases （73.5 % ） , 0 case of type Ⅰ. Conclusions DCE -- MRI is an important method to diagnose and differentiate the breast tumor.
