Background: To investigate the value of ultrasound elastography (UE) in the differentiation between benignand malignant enlarged cervical lymph nodes (LNs).
Methods: B-mode ultrasound, power Doppler imaging andUE were examined to determine LN characteristics. Two kinds of methods, 4 scores of elastographic classificationand a strain ratio (SR) were used to evaluate the ultrasound elastograms.
Results: The cutoff point of SR hadhigh utility in differential diagnosis of benign and malignant of cervical lymph nodes, with good sensitivity,specificity and accuracy.
Conclusion: UE is an important aid in differential diagnosis of benign and malignantcervical LNs.
