螺旋CT对乳腺疾病的诊断价值

The Value of Spiral CT in Breast Diseases

目的:评价螺旋CT在乳腺疾病诊断中的应用价值。材料与方法:对26例乳腺疾病胸部CT平扫的图像进行回顾性分析,男性2例,女性24例,年龄36岁～84岁,平均56岁。恶性病变22例,包括浸润性导管癌20例,转移性腺癌2例,良性病变4例,包括纤维腺瘤2例,乳腺脂肪坏死2例,均经病理证实。分析乳腺病变的形态学表现,并测量CT值进行定量评价。结果:毛刺征、病变周围脂肪组织模糊及乳后脂肪间隙狭窄在良、恶性病变间具有统计学差异(p<0.05);良性病变、恶性病变与正常乳腺组织CT值之间具有统计学意义(p<0.05),而良性纤维腺瘤与浸润性导管癌CT值之间无统计学意义(p>0.05)。淋巴结转移多表现为淋巴结门结构消失、密度增高、肿大,部分有融合趋势。结论:螺旋CT图像的密度分辨力高,清晰显示乳腺的解剖结构及乳腺病变的形态、密度及周边情况,观察胸壁、双肺及淋巴结等转移情况具有无可比拟的优越性。

Purpose：To evaluate the applied value of CT in breast lesions.Materials and Methods：CT imaging data of 26 patients with breast diseases were reviwed retrospectively.There were 2 male and 24 female,aged 36～84 years old,20 patients were malignant tumors,included 20 duct carcinoma,2 metastasis.4 were benign lesions,included 2 fibromas and 2 liponecrosis.they were certified by pathology.Their imaging features were analysized.Results：The signs of spiculated lesion,deformed adipose space were statistical difference between benign and malignant lesions（P 0.05）;The difference of density between lesions and normal breast tissue at plain CT was statistically significant（P0.05） .but The difference of density between benign fibromas and duct carcinoma were not statistically significant（P0.05）. The metastatic axillary lymphnodes usually showed as the significant enlarged nodes with indefinite margin or multiple small nodes.Conclusion：Image of CT has high density resolution,anatomy of normal breast and formation,density and margin of lesions could be shown clearly,simutaneously,metastasis of thorax wall,long and lymphonodus could be viewed.
