目的　分析乳腺良恶性肿瘤的钼靶X线表现特征 ,以提高鉴别诊断水平。方法　对经术后病理检查证实的 98例乳腺肿瘤钼靶X线表现特征进行对照分析 ,其中恶性 67例 ,良性 3 1例。结果　毛刺状肿块、细微簇样钙化是乳腺恶性肿瘤特异性X线征象。良恶性肿瘤X线诊断准确率分别为 84%和 89.6%。结论　乳腺钼靶X线摄影是鉴别良恶性肿瘤的有效影像学方法

Differential Diagnosis of Benign and Malignant Breast Neoplasms Demonstrated by Mammography

Objective To evaluate the X-ray characterstics of benign and malignant neoplasms on mammography in order to improve their differeatial diagnostic level.Methods X-ray image changes of 67 malignant breast neoplasms were described by the mammography and in comparision with those of 31 benign masses .Results The accordance percentages between the X-ray and histological examinations for the malignant and benigin neoplasms were shown to be 89.6% and 84.0% respectively. Occurrence of masses with an enhanced density , irregular shape, calcification granules in clusters were found to be indication of a malignent lesion.Conclusion The mamography can provide effective imaging data for differential diagnosis betweren the benign and malignant breast neoplasms.
