Abstract：Objective:To investigate the value of ultrasonic elasticity imaging on diagnosis of thyroid cancer.Method:52 patients with thyroid cancer were selected as the research object from January 2013 to June 2015 in our hospital.All patients were confirmed by needle biopsy of thyroid micro carcinoma and received conventional ultrasound and contrast-enhanced ultrasound elasticity imaging,the diagnosis result of conventional ultrasound and ultrasound elasticity imaging on diagnosis of thyroid micro carcinoma were compared and analyzed the features of thyroid micro carcinoma on ultrasound elasticity imaging.Result:Pathology experiment proved that there were 69 lesions in 52 patients,conventional doppler echocardiography confirmed there were 50 lesions in 40 patients,ultrasound elasticity imaging proved there were 64 lesions in 50 patients,the results of elasticity imaging diagnosis and pathological showed no significant differences,but the positive rate was significantly higher than conventional ultrasound,there was a statistical significance(P＜0.05).According to the evaluation criteria of different pathological types of classification of elastic ultrasonic evaluation of thyroid micro carcinoma,the grading result comparison difference was statistically significant(P＜0.05).Conclusion: Ultrasound elasticity imaging has high sensitivity on detecting thyroid micro carcinoma,it can improve detection rate of clinical thyroid micro carcinoma and has high safety,which is beneficial to repeatedly checking and with clinical application and popularization value.
