目的 探讨CT和钼靶摄影诊断乳房肿块的价值。方法 对经病理证实的 61例乳房肿块的CT和钼靶征象进行对照研究 ,分析其诊断准确性。结果 CT对乳腺癌、乳房积乳囊肿、脂肪瘤、纤维腺瘤、男性乳腺发育症 (肿块型 )、女性乳腺增生症的诊断符合率分别为 80 % (8/10 )、10 0 % (2 /2 )、10 0 % (1/1)、10 0 % (2 7/2 7)、10 0 % (7/7)、10 0 % (14 /14 ) ;钼靶摄影的诊断符合率分别为 70 %(7/10 )、5 0 % (1/2 )、0 % (0 /1)、81% (2 2 /2 7)、43 % (3 /7)、71% (10 /14 )。本组 10例乳腺癌中钼靶摄影有 4例占 40 % (4 /10 )显示成簇样微小钙化 ,而CT无 1例显示。钼靶摄影显示成簇样微小钙化优于CT。CT和钼靶摄影对乳房肿块的诊断准确率分别为 97%和71%。结论 CT对肿块的定性诊断准确率高于钼靶检查 ,两者综合应用可提高对早期乳腺癌的诊断水平。
Objective To investigate the value of CT and mammography in the diagnosis of breast lumps. Methods The CT and mammographic signs of 61 breast masses confirmed by pathology were compared and the diagnostic accuracy was analyzed. Results The diagnostic rates of CT were 80% (8/10) and 100% (2) respectively for breast cancer, breast milk cyst, lipoma, fibroadenoma, male mammary gland disease (tumor type) and female hyperplasia of mammary gland / 2), 10 0% (1/1), 100% (2 7/2 7), 10 0% (7/7) and 10 0% (14/14) Were 70% (7/10), 50% (1/2), 0% (0/1), 81% (2 2/27), 43% (3/7), 71% ). Four cases (40%) of 10 mammograms in this group showed clustered microcalcifications, while none of the CTs showed CT. Mammography showed clusters of fine calcifications superior to CT. The diagnostic accuracy of CT and mammography for breast lumps was 97% and 71%, respectively. Conclusion The diagnostic accuracy of CT in the diagnosis of lumps is higher than that of molybdenum target. The combination of both can improve the diagnosis of early breast cancer.
