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。尤其是Ⅳc型更甚
Objective: To investigate the characteristics of breast mammography in the diagnosis of breast cancer so as to improve the diagnostic level. Methods: Two hundred and fifty cases of breast cancer confirmed by surgery and pathology after X-ray diagnosis in the past two years were collected. Results: The age group of 36-55 years old was high incidence of breast cancer, accounting for 60.8%. 56 to 65 age group has a downward trend, accounting for 22.8%. The incidence of extramacular upper quadrant of the breast more common, accounting for 59.2%. Simple cancer incidence, accounting for 40.4%, followed by invasive ductal cancer, accounting for 32.0%. 250 cases of breast cancer X-ray showed that the mass accounted for 94.8%, X-ray showed edge fuzzy mass accounted for 34.4%, lobular accounted for 25.2%, burr accounted for 27.2%, 104 cases showed malignant calcification (41.6%). Conclusion: The features of X-ray images of breast cancer are mostly mass-type. The main features are fuzzy blisters, burr-like and lobulated. Most of the masses are not smooth and dense in center. ② breast small granular calcification morphology and benign small calcification can be identified. ③ clear breast type Ⅱ b, Ⅲ c, Ⅳ c, is a high incidence of breast cancer type. In particular, type Ⅳ c even worse
