Abstract：Objective To evaluate the clinical value of strain ratio using real‐time elastosonography in differential diagno‐sis of benign and malignant superficial cervical lymph nodes .Methods Elasticity imaging was used to examine 38 healthy volunteers with 66 benign lymph nodes and 70 lung cancer patients with 70 malignant lymph nodes .The stain ratio was obtained through normal soft tissues and lymph nodes .ROC (Receiver operation characteristic ) curves were plotted to e‐valuate the diagnostic performance of strain ratio .Results There were 70 malignant lymph nodes and 66 benign ones in our research .The mean of elastic stain ratio of benign and malignant was 2 .53 ± 0 .82 and 1 .08 ± 0 .49 ( P <0 .05) .The cut off point of stain ratio was determined as 1 .950 .The sensitivity ,specificity ,and accuracy were 77 .0% ,97 .0% and 86 .8% respectively in differential diagnosis of benign and malignant cervical lymph nodes .The area under the curve was 0 .918 .Conclusion The stain ratio is valuable for the differential diagnosis of malignant and benign cervical lymph nodes .
