ABSTRACT

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.
