摘　　要：目的 探讨小乳癌的钼靶和CT主要表现,以提高乳腺癌的早期诊断率。方法 收集18例小乳癌(肿癌直径≤2.0cm)的钼靶和CT的影像学资料,与手术病理作对照分析。结果 小乳癌CT诊断的准确性为83%,钼靶为61%,CT明显高于钼靶。但萎缩型乳房的小乳癌钼靶与CT诊断结果相同;对微小钙化的发现,CT不如钼靶敏感。结论 临床疑为小乳癌的患者应先行钼靶检查,必要时再行CT检查。二者结合可提高乳腺癌的早期诊断率。Objective To improve tne early diagnosis of breast cancer through a study of the mammography and CT findings of small breast cancer. Methods The mammography and CT findings of 18 cases of small breast cancer(φ≤2.0 cm in diameter) were studied and compared with pathological results. Results The diag-nostic accuracy of CT and mammography was 83% and 61% , respectively. There was a statistical difference between both modalities (P<0.05), CT scan was superior to mammography. However, there was no difference between them when assessing the lesion arising in F-type breast. In detecting breast fine cluster of calcification, the sensitivity of mammography was better than CT scan. Conclusion The patient suspected of small breast cancer should take mammography as the first evaluation. CT scan is reserved for the further investigation. The mammography combined with CT scan can improve the early diagnostic rate of breast cancer.
