在数字钼靶环境下研究早期乳腺癌的影像特点

Molybdenum Target in the digital environment, to study the image characteristics of early breast cancer

目的提高钼铑双靶X线对早期乳腺癌诊断的准确性。方法对41例经手术及病理证实早期乳腺癌X线征象进行回顾性分析。结果早期乳腺癌征象：结节状肿块23例；钙化17例，X线未见明确肿块或结节而钙化灶为惟一恶性征象2例；非对称性密度增高12例；局限性皮肤增厚伴乳头凹陷2例。结论①肿块是早期乳腺癌重要的诊断依据；②微细钙化仍是早期乳腺癌重要的诊断依据，甚至比直接征象（肿块）更具特异性；③非对称性局限性致密、乳腺结构局部扭曲紊乱，在排除炎性反应和手术史后，应考虑乳腺癌可能；④除恶性钙化外，大于两种间接征象并存时，应高度重视，予以进一步检查或短期复查。

Objective To improve the pairs of molybdenum and rhodium target X ray of early breast cancer diagnostic accuracy. Methods 41 cases confirmed by surgery and pathology of early breast cancer X ray findings were analyzed retrospectively. Results signs of early breast cancer： 23 cases of nodular masses; calcification in 17 cases, X ray no clear lumps or nodules and calcification of the only 2 cases of malignant signs; non-symmetry of high density 12; limitations associated with skin thickening nipple retraction in 2 cases. Conclusion （1）mass is an important basis for the diagnosis of early breast cancer;（2）micro-calcification is still an important basis for the diagnosis of early breast cancer, even more than the direct signs of （mass） more specific ;（3）non-symmetry of the limitations of dense breast structure of local distortions disorders, inflammation and surgical history of the exclusion, it should be possible to consider breast cancer;（4）In addition to malignant calcification, the more than two kinds of indirect signs of co-exist, we should attach great importance to be further examination or short-term review.
