Abstract Objective：To evaluate the application value of ultrasonic elastography strain ratio combined with two-dimensional ultrasound in diagnosis of thyroid nodules. Method：Two-dimensional ultrasound and elastic strain ratio elastography examination were both performed in 74 patients with 102 thyroid nodules.The results of ultrasonic diagnosis and pathological results were analyzed.Result：According to the sonographic features of two-dimensional ultrasound， the diagnostic accuracy rate of thyroid nodules was 62.7%. According to the accurate rate of elastic strain ratio in diagnosis of thyroid nodules was 55.9%. Combining the two-dimensional ultrasonographic features of ultrasonic elastic strain rate， the accuracy rate of ultrasonic diagnosis of thyroid nodules was 83.3%， compared with the first two methods were statistically significant（ P<0.05）.Conclusion：Ultrasound elastic strain ratio combined with two-dimensional ultrasound significantly improves the diagnostic accuracy rate of ultrasound diagnosis of thyroid nodules.
