Aims and objectives: To evaluate the use of spectral CT quantitative parameters for diagnosis of metastatic axillary lymph nodes in patients diagnosed with IDC.

Methods and materials: 56 patients with IDC who underwent contrast-enhanced chest spectral CT for evaluation of suspicious lung nodules were enrolled. All the patients were identified having suspected axillary lymph nodes evaluated on ultrasound.The status of specific axillary lymph node was documented for each other. Mea[...]

Results: 56 females(mean age 51, range from 34-77) were enrolled in the study, and the largest diameter of the tumors was measured varying from 0.6-6.1cm (mean 2.4cm). Of 56 suspected axillary lymph nodes, metastatic evidence confirmed pathologically was 38,while 18 were presented no evidence of metastasis.T[...]

Conclusion: The preliminary study demonstrated that GSI parameters measured for the primary breast lesion were well correlated with those metastatic axillary lymph node.Preoperative spectral CT might be used to evaluate metastatic axillary lymph nodes in primary breast carcinoma through the furth[...]
