早期乳腺癌的X线摄影与CT的对照研究

目的：探讨早期乳腺癌的X线和CT的特征性表现．提高其诊断率。方法：50例乳腺癌和20例乳腺良性病变均行X线和CT检查，乳腺摄片时间为月经后10d内．所有病例均经病理证实。结果：X线诊断早期乳腺癌39例，其敏感性和特异性分别为78．4％和85％，准确性为80％。CT诊断早期乳腺癌42例，其敏感性和特异性分别为84％和80％，准确性为82．9％。二者综合诊断，其敏感性和特异性为81．2％和82．5％，准确性为81．4％。结论：二者综合检查可提高早期乳腺癌诊断的敏感性和准确性。

Controlled Study of Mammography with CT for the Diagnosis of Early Breast Cancer

Objective: To study the Mammographic and CT characteristics of early breast cancer, and to improve its diagnostic accuracy.Methods:Fifty patients with breast cancers and 20 patients with benign breast masses,proved path ologically,underwent mammography and CT in 10 days after menses.Results: Mammography demonstrated breast cancer in 39 cases, the sensitivity and specificity were 78.4% and 85%,respectively,with the accuracy of 80.0%;while CT revealed breast cancer in 42 cases,the sensitivity and specificity were 84% and 80%,respectively,with the accuracy of 82.9%.The sensitivity,specificity and accuracy could reach to 81.2%,82.5%and 81.4% ;respectively when mammography and CT were combined together.Conclusion:Mammography combined with CT can increase the diagnostic rate and accuracy of early breast cancers.
