摘　　要：目的　探讨CT扫描对小乳癌、隐匿性乳癌及腋窝淋巴结转移的诊断及对手术方式选择的指导价值。方法　采用俯卧位或仰卧位 ,扫描范围一般自乳房下界至腑窝顶 ,发现病变部位行薄层扫描 ,快速注入造影剂后测量相应层面的最高CT值。结果　CT扫描对小乳癌诊断准确性明显优于其它影像诊断方法 ,腋窝淋巴结转移的诊断假阳性及假阴性率较高。结论　CT扫描对小乳癌的诊断有一定价值。因腋窝淋巴结转移的诊断假阴性及假阳性率较高 ,对手术方式的选择仅供参考 。Objective To investigate the evaluation of CT scan in the diagnosis and operation choice of the mini-breast cancer,occult cancer and axillary lymphatic metastasis. Methods In supine or prone position,scan rangs is from inferior margin of the breast to the roof of the axillary fossa. If abnormal are fond,additional thin slices are performed with contrast. Results The diagnostic accuracy of CT scan is significant higher than other image exams,but the false postive and false negative rates are guite high in occult breast cancer and axillary lymphatic metastasis. Conclusion CT scan has some evaluation in mini-breast cancer diagnosis,but it is not suitable to evaluate the axillary lymphatic metastasis,it can not be the foundation of operation choice. [
