Abstract

Purpose: To evaluate the accuracy of strain elastography in the diagnosis of malignant axillary lymph nodes.


Methods: B-mode and strain elastography US were scanned by experienced radiologists on patients with clinical symptoms or suspicion of breast cancer to look for masses or abnormal lymph node. Lymph nodes are evaluated on B-mode ultrasound based on 4 factors: short and long axis diameter, hilum, and cortical thickening. The strain elastography was based on a color scale of 1 to 5 points based on percentage of nodal region on the color chart, and a semi-quantitative B/A index of node stiffness correlation with adipose tissue of the same depth.


Results: a total of 41 lympho nodes (benign, n=13, malignant, n=28) from 39 patients were analyzed. B-mode ultrasonography in the evaluation of malignancy had a sensitivity and specificity of 67.9% and 69.2%. Strain elastography for assessment of axillary lymph node involvement had a sensitivity and specificity of 85.7% and 69.2%. The semi-quantitative index B/A had statistically significant difference between the group of benign and malignant lymph nodes (p<0.05) with the cut of is 23.5. Conclusion: Strain elastography is a non-invasive and helpful method, together with B-mode ultrasound, in the evaluation of malignant axillary lymph node involvement
