B-mode ultras

Aim: To evaluate role of B-mode ultrasound, ultrasound elastography and DWI in differentiating benign and malignant axillary lymph nodes. Patients and methods: From July 2014 to July 2015, 30 patients with enlarged axillary nodes in patients with malignant breast disease were examined by B mode ultrasound, US elastography and DWI. Finally, findings of B-mode US, elastography and DWI were compared with pathological results (reference standard). ROC analysis was constructed to obtain best cutoff values for B-mode criteria: elasticity score, strain ratio and ADC value. Results: Mean SR of malignant nodes (8.26) was significantly higher than that of benign nodes (2.08) with P value <0.0001. Mean ADC value of malignant nodes (0.7) was significantly lower than mean ADC value of benign nodes (1.4) with P value
