乳腺良恶性钙化的钼靶X线影像分析

摘要

Objective To explore the image features of benign and malignant calcification of mammary gland in full digital X-ray photography for mammary gland. Methods Convenient selection 102 female patients with calcification nidus found in molybdenum target examination of mammary gland in the radiology department from January 2014 to December 2015 were selected as the research objects. Retrospective analysis was carried out for the morphology, distribution, quantity, diameter and density of calcification. With referred to pathologic results, the patients were divided into two groups -- benign group (46 cases) and malignant group(56 cases) The morphology,distribution,quantity,diameter and density of calcification were an-alyzed retrospectively. Results The typical morphologic features of benign group were transparent center, orbits, coarse par-ticle, popcorn-shaped, eggshell-shaped, round, and coarse rod-shaped; while the typical morphologic features of malignant group were fine particle, fine rod-shaped, branched, and irregular polygons. There were statistically significant differences between malignant calcification and benign calcification in quantity, diameter, density and distribution (P<0.05). Conclu-sion The X-ray image features of mammary gland calcification have great value in distinguishing malignant calcification from benign calcification of mammary gland.%目的：探讨乳腺良恶性钙化在全数字化乳腺 X线摄影中的影像特征。方法方便选取2014年1月—2015年12月在该院放射科行乳腺钼靶检查发现钙化病灶的102例女性患者作为研究对象，与病理结果对照，将其分为良性钙化46例、恶性钙化56例，对钙化的形态、分布、数量、直径、密度进行回顾性分析。结果良性钙化典型形态为中心透亮、轨道状、粗颗粒、爆米花状、蛋壳状、环形、粗棒状；恶性钙化典型形态多为细沙颗粒状、细杆状、分支状、不规则多角形。良性组与恶性组在钙化数量、直径、密度及分布的影像比较中差异具有统计学意义(P<0.05)。结论乳腺钙化的X线影像特征在乳腺良恶性病变的鉴别诊断中具有重要价值。
