乳腺肿瘤的钼靶X线诊断及其摄影技术探讨

目的探讨乳腺肿瘤的钼靶X线特征及钼钯X线摄影技术要求。方法收集分析200例经手术、穿刺活检证实的乳腺肿瘤的钼靶X线摄影资料。结果乳腺良性肿瘤138例,X线征象多为圆形、椭圆形肿块,临床触诊质地较软。62例乳腺癌钼靶X线征象为不规则形肿块37例,占59.7%;类圆形25例,占40.3%。有微小钙化32例,占51.6%;局部浸润4例,占6.5%。触诊质地较硬,X线测量比值小于临床。结论X线钼靶摄影是乳腺肿瘤首选检查方法,显示乳腺癌的主要直接征象和间接征象,在乳腺癌的早期诊断及鉴别诊断中很有价值。

Study of Mammographic Diagnosis and Technique in Mammary Tumor

Objective To explore the mammographic characteristics and technique in mammary tumor.Methods The mammographic materials of 200 cases with breast tumors which were confirmed by surgery, ultrasonography, biopsy or clinic follow-up were collected and analyzed retrospectively.Results Benign mammary tumors were found in 138 cases. They were the masses with round or ellipse in shape mammographically and soft clinically. In 62 cases of breast cancer, the mammogram showed irregular masses in 37 cases (59.7%), oval in 25 (40.3%), clustered tiny calcification in 32 (51.6%) and local infiltration in 4 (6.5%). The masses were hard on palpation, and their sizes were smaller on mammogram than that on palpation. Conclusion mammography is the initial modality for breast tumor, which can demonstrate main direct and indirect signs of the breast cancer, and shares high value in early diagnosis and differential diagnosis of the disease.
