Application of mammography in the diagnosis of breast calcification
Objective To analyze the practical effect of mammography in the diagnosis of breast calcification. Methods Clinical data of 56 patients with breast diseases were selected for retrospective analysis. All the enrolled patients were subjected to mammography examination. Meanwhile,the diagnostic accuracy of mammography for breast calcification was analyzed with the results of surgical pathologic examination as the diagnostic gold standard. At the same time,the size,shape,distribution and benign and malignant lesions of breast calcifications were analyzed. Results The surgical pathologic diagnosis of 56 patients showed that 47 cases had calcification in malignant lesions and 9 cases had calcifications in benign lesions;mammography showed 14 cases had extremely dense breast calcification,13 cases had uneven dense breast calcification,16 cases had scattered fibroadenoid breast calcification,and 10 cases had fatty breast calcification. The diagnostic accuracy of mammography was 94.64％ (53/56) based on the gold standard of surgical pathological diagnosis. The patients were divided into 7 types according to the size and shape of the calcified foci:(i) small calcified spots in the breast,<1 mm in diameter,distributed in clusters,with no obvious difference in the shape and size of the spots;(ii) foci of calcification were in the shape of crushed stones,>1 mm in diameter;(iii) the calcifications were in the shape of small forks,aggregated,with the shape of clubs,with the diameter of 1-3 mm;(iv) the calcifications were in the shape of irregular;(v) the foci were in the shape of round holes;(vi) the calcifications were in the shape of curved eggshells;(vii) calcifications were in the form of orbits and bars. According to the distribution of calcification foci,they could be categorized as diffuse,regional,isolated,clustered,linear or segmental distribution. Characteristics of benign lesions:the main forms of fibroadenoma were vacuolar calcification and coarse calcification;the calcification of breast hyperplasia had multiple forms,and its form was mainly granular. Malignant lesions were characterized by forked calcifications,sandy calcifications,short-rod calcifications,and diffuse calcifications. Benign calcifications were usually found in fat and tissue,while malignant calcifications were commonly found in cancerous areas. Conclusion The effect of mammography in the diagnosis of breast calcification is significant,and this diagnosis method is worthy of clinical application.
