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。结论 CT对乳房良性疾病的定位和定性诊断正确率均高于钼靶摄片检查
Objective To evaluate the value of CT in the diagnosis of benign breast diseases. Methods Forty-four patients (78 lesions) underwent breast CT and mammography. Comparative analysis of the two methods of detection of breast benign disease localization and qualitative accuracy. All cases were confirmed by pathological benign disease. Results CT had a definite diagnosis on breast fibroma and breast cysts. The diagnosis of breast deep lesions, multiple breast benign lesions and multiple benign lesions was better than molybdenum target radiography. The positive rates of CT scan and mammography for benign breast diseases were 85% and 54%, respectively. There was a statistically significant difference between them (χ2 = 8.29, P <0.01) The correct rates were 85% and 60% respectively. There was a statistically significant difference between the two groups (χ2 = 12.58, P <0.01). Conclusion The correct rate of localization and qualitative diagnosis of benign breast diseases by CT is higher than that of molybdenum target radiography
