目的探讨磁共振成像(MRI)对乳腺浸润性导管癌的临床应用价值。方法回顾性分析了2012年1月至2012年6月期间在四川大学华西医院放射科行MRI检查,且术后经病理学检查证实为乳腺浸润性导管癌的75例患者的术前MRI检查资料。结果形态学分型:团块型54例,结节型21例,囊实混合型0例。肿块形状:圆形3例,卵圆形9例,不规则形63例。边缘:不规则66例,规则9例;呈微小分叶状56例。肿块内有钙化者1例。有淋巴结转移者18例。MRI的T1WI呈低信号(65例)或等信号(10例),T2WI呈低信号(3例)或以稍高信号为主的混杂信号(72例),增强后大部分呈均匀强化(64例),部分呈不均匀强化(11例)。结论通过分析乳腺浸润性导管癌的MRI成像特征,可为临床诊断乳腺浸润性导管癌提供有力的影像学证据。
Objective To investigate the clinical value of magnetic resonance imaging (MRI) in breast invasive ductal carcinoma. Methods A retrospective analysis was performed on the MRI data of 75 patients who had MRI examination of Radiology department of West China Hospital of Sichuan University from January 2012 to June 2012 and pathologically confirmed as breast invasive ductal carcinoma . Results Morphological classification: 54 cases of lumps, nodules in 21 cases, cystic solid mixed type in 0 cases. Lump shape: round in 3 cases, oval in 9 cases, 63 cases of irregular shape. Margins: irregular 66 cases, the rules of 9 cases; 56 cases were minute lobulation. There are 1 cases of calcification in the mass. There are 18 cases of lymph node metastasis. MRI T1WI showed low signal (65 cases) or equal signal (10 cases), T2WI low signal (3 cases) or slightly higher signal mainly mixed signal (72 cases), most of the enhancement was uniform enhancement Cases), part of the uneven enhancement (11 cases). Conclusion The MRI features of breast invasive ductal carcinoma can provide powerful imaging evidences for clinical diagnosis of invasive ductal carcinoma of the breast.
