目的：探讨 MSCT双期增强扫描对乳腺癌及早期淋巴结转移的应用价值。方法收集病理证实的浸润性乳腺癌(IDC)30例为研究组,纤维腺瘤30例为对照组,术前行128排CT胸部平扫+双期扫描,比较2组肿块的征象差异和分析早期淋巴结转移的影像表现。结果 IDC的 MSCT表现：肿块多为形状不规则,边缘毛刺,动脉期呈明显强化,静脉期呈持续性强化,可见环形强化。2组在肿块形状、边缘、强化方式等存在显著性差异(P<0.05)。MSCT发现淋巴结转移22例,6例无明显增大,仅增强后明显强化。结论 MSCT双期增强扫描对乳腺癌及早期淋巴结转移具有良好的临床应用价值。

Objective To investigate the application of multi-sliced CT on breast cancer and early lymph node metastasis (LNM). Methods 30 cases with infiltrative ductal carcinoma (IDC)confirmed by pathology were collected and set as Study Group,30 fibro-mas as Control Group.128-slice CT plain and 2 phrase enhance scan was undergone.Image signs of mass of two groups were com-pared.Image signs of early lymph node metastasis were analyzed.Results In MSCT images,IDC masses had irregular shape,burr rim.2-phrase MSCI demonstrated obvious enhancement in artery phrase,persistence enhancement in vein phrase and ring shape en-hancement.There were significant different between 2 groups in mass shape,rim and enhancement mode(P<0.05).MSCT demon-strated 22 LNM,but 6 of them had no swelling but obvious enhancement.Conclusion 2-phrase MSCT plays an important role in as-sessing breast cancer and early lymph node metastasis.
