摘　　要：目的：探讨乳腺X线非弥漫分布钙化对乳腺良恶性病变的诊断意义。方法收集行全数字化乳腺X线摄影并经手术病理证实的病变379例，对病变钙化的形态、分布、数目、直径、密集度、密度、钙化范围最大径、钙化伴有情况在良恶性钙化中进行统计分析。结果钙化形态：恶性细小多形性较多占58．5％，良性点状较多占49．3％；线样或线样分支状均为恶性，圆形均为良性。钙化分布：恶性区域性分布较多占43．9％，良性成簇分布较多占58．4％；叶段分布均为恶性。钙化直径：恶性＜0．5mm较多占71．6％，良性＞1．0 m m较多占69．3％。钙化密集度：恶性＞25枚较多占71．8％，良性15～25枚较多占58．4％。钙化密度：恶性不均匀居多占94．2％，良性均匀居多占63．4％。钙化范围最大径：恶性在40～80 m m占59．0％，良性在0～40 m m占77．2％。结论乳腺非弥漫分布钙化的形态、分布、直径、密集度、密度、钙化范围最大径在乳腺良恶性病变中有统计学差异。Objective To discuss the clinical significance of the diffuse calcified distribution in diagnosis of benign and malignant breast lesions .Methods 379 patients with different benign and malignant breast lesions confirmed by surgery underwent digital X‐ray mammography .The morphology ,distribution ,number ,diameter ,concentration and density of calcification in lesions ,the maximum range of the calcified area and other accompanied manifestations in benign and malignant breast lesions were analyzed .Results As for the morphology of calcification ,tiny polymorphic calcification was found in 58 .5% of malignant lesions ,meanwhile ,dot‐like one was found in 49 .3% of benign lesions .Fine linear calcification or branched linear one occurred in malignant lesions ,however ,round one occurred in benign lesions .As for the calcification distribution ,regional distribution was found in 43 .9% of malignant lesions , meanwhile the clustered distribution was found in 58 .4% of benign lesions .And all lobar or segmental distribution was seen in malig‐nant lesions .As for the calcification diameter ,the calcification with the diameter less than 0 .5 mm occurred in 71 .6% of malignant lesions ,however ,that with diameter more than 1 .0 cm occurred in 69 .3% of benign lesions .As for the concentration of calcification , lesions with calcification more than 25 were 71 .8% of malignant ones ,whereas those with calcification of 15-25 were 58 .4% of be‐nign ones .As for calcified density ,uneven calcification occurred in 94 .2% of malignant lesions ;however the even one occurred in 63 .4% of benign lesions .The maximum diameter of calcification ranged from 40 mm to 80 mm was found in 59 .0% of malignant lesions , whereas that ranged from 0 mm to 40 mm was in 77 .2% of benign lesions .Conclusion Statistical differences have been found in the morphology ,distribution ,diameter ,concentration ,density and maximum diameter of calcification between the breast benign and ma‐lignant lesions .
