目的 评价乳腺癌的CT诊断价值。材料与方法 回顾性分析了25例经病理证实的乳腺癌CT征象,25例均作CT平扫,17例平扫后做增强扫描。结果 乳腺癌CT多表现为结节状,边缘毛刺、尖角及细小的簇状钙化具有一定的特征;增强后癌灶常明显强化,有助于发现隐匿性病灶;乳头后方的病灶易引起皮肤增厚;腋窝淋巴结大于1cm,转移较肯定。结论 CT在乳腺癌的诊断、显示病灶范围和腋窝淋巴结转移有重要价值。 Objective To evaluate the diagnostic value of CT in breast cancer. Materials and Methods Retrospective analysis of 25 cases of pathologically confirmed breast cancer CT signs, 25 cases were plain CT scan, 17 cases after plain scan to do enhanced scan. Results Most of the CT appearances of breast cancer were nodular. The edge burrs, sharp corners, and tiny cluster calcifications had certain characteristics. The enhanced lesions were often enhanced and could help to find occult lesions. The lesions behind the nipples could cause skin easily. Thickening; axillary lymph nodes greater than 1cm, the transfer is more positive. Conclusion CT has important value in the diagnosis of breast cancer, showing the extent of lesions and axillary lymph node metastasis.
