摘　　要：目的探讨触诊阴性乳腺普通性导管增生与导管原位癌钙化的数字化X线片摄影(DR)征象及鉴别要点。方法回顾性分析经手术、病理证实的乳腺普通性导管增生43例,导管原位癌41例,临床均未触及肿块,对二者DR征象进行对比和统计学处理。结果钙化灶延伸方向、钙化分布、钙化形态及血管情况差异有统计学意义;而钙化灶长径、钙化数目、钙化大小及密度无显著差异。结论触诊阴性乳腺普通性导管增生与导管原位癌钙化DR多表现为以低密度细钙化为主,鉴别要点包括钙化灶延伸方向、是否可见簇拥征及线状钙化,并结合血管情况综合分析。Objective To investigate digital radiology （DR） signs and differential diagnosis of nonpalpabel breast calcifications between usual ductal heperplasia and ductal carcinoma in suit. Methods Nonpalpabel 43 usual ductal heperplasia lesions and 41 ductal carcinoma in suit lesions of breast were analyzed retrospectively, which were verified by surgery and pathology, both DR signs comparative analysed and statistics processed. Results Calcifica‐tions extension direction, distribution, morphological and vascular had statistically significant, but calcifications lesion length to diameter, number, size and density did not have significant difference. Conclusion More performance were given priority to with low density fine calcifications of nonpalpabel breast usual ductal heperplasia and ductal carcino‐ma in suit, identify key points including calcifications extension direction, whether visible cluster round sign and linear calcification, comprehensive analysed and combined with vascular conditions.
