摘　　要：目的:探讨乳腺钼靶X线摄影诊断乳腺癌的特点,以提高诊断水平。方法:收集近2年来经X线诊断后,手术和病理证实的乳腺癌250例。结果:36～55岁为乳腺癌高发年龄组,占60.8% 。56～65岁年龄组有下降趋势,占22.8% 。发病部位在乳腺外上象限较多见,占59.2% 。单纯癌发病高,占40.4% ,其次为浸润性导管癌,占32.0% 。250例乳腺癌X线片显示肿块占94.8% ,X线显示边缘模糊肿块影占34.4% ,分叶状占25.2% ,毛刺样占27.2% ,显示恶性钙化104 例(41.6% )。结论:①乳腺癌的X线影像特征多以肿块型为主,主要显示边缘模糊肿块,毛刺样及分叶状,肿块大多边缘不光滑而中心致密。②乳腺癌小颗粒状钙化形态特点与良性小钙化点可以鉴别。③明确乳腺类型Ⅱb、Ⅲc、Ⅳc、是乳腺癌高发类型。Objective:To investigate the clinical features of the mammogram by molybdenum targets roentgenography in order to improve the diagnostic level of breast carcinoma.Methods:Two hundred and fifty cases of breast carcinoma confirmed by operation and pathology were studied.Results:There was a high incidence(60.8%) in the age group of 36～55 years.The incidence become lower(22.8%)in the age of 56～65 yeara.The outer-upper quadrant of the breast was the major position of lesion(59.2%).Simple carcinoma was a high incidence(40.4%)and the secondary was infiltrating duct carcinoma(32.0%).The mass was the main type of lesion in 250 cases,it made up 94.8%,in which the dim border mass was 34.4%,the foliar mass was 25.2% and the spicula mass was 27.2%.104 cases had malignant calcifications.Conclusion:①The roentgenologic characteristics of berast carcinoma are mainly mass which showed dim border,spicula and foliar.The lesions are characterized by a rough border and compact in center.②The characteristics of small granular calcifications of breast carcinoma can be differentiated from benign small calciffication.③The breast type of Ⅱb,Ⅲc,Ⅳc especially Ⅳc are of high incidence of the breast carcinoma.
