CT在诊断乳房良性疾病中的应用

CT application in diagnosing benign diseases of breast

目的 评价CT诊断乳房良性疾病的价值。方法 44例 (78个病灶 )患者接受乳房CT扫描和钼靶摄片检查。对比分析这两种检查方法对乳房良性疾病的定位和定性准确性。所有病例经病理证实均为良性疾病。结果 CT对乳房纤维瘤和乳房囊肿有明确诊断作用 ,对乳房深部病灶、乳房多发性及多样性良性病变的诊断优于钼靶摄片检查。CT扫描和钼靶摄片对乳房良性疾病的定位正确率分别为 85 %和 5 4% ,两者比较 ,统计学上有非常显著性差异 ,χ2 =8.2 9,P <0 .0 1;定性正确率为 85 %和 6 0 % ,两者比较 ,统计学上有非常显著性差异 ,χ2 =12 .5 8,P <0 .0 1。

Objectiv To evaluate the value of CT for diagnosing benign diseases of breast Methods The breast CT scan and mammography were performed on 44 patients (78 focus) The accuracy of determining the position and nature of breast diseases was compared between the two mentioned diagnostic methods All cases were confirmed as breast benign disease by pathology Results CT played a remarkable role in the diagnosis of breast fibroadenoma and cyst, and is superior to mammography in demonstrating deep breast lesion, multiple focus and multiple patterns benign diseases of breast The accuracy of CT and mammography in determining the position and nature of benign diseases of breast were 85% and 54%(χ 2=12.58, P <0.01), 85% and 60%(χ 2=8.29, P < 0.01) respectively Conclusion CT has a higher accuracy than mammography in determining the position and nature of breast benign disease
