Abstract:
Objective To study the clinical significance of combined routine ultrasound and ultrasound elastography in diagnosing thyroid microcarcinoma so as to facilitate the diagnoses of the thyroid diseases of the pilot.Methods Totally 284 thyroid nodules with the sizes less than 1 cm underwent routine ultrasound and ultrasound elastography examinations from June 2013 to June 2016.Results There were 221 benign nodules (77.8%) and 63 malignant ones (22.2%) confirmed by FNAC cytological,surgical and pathological examinations.Of the 63 malignant nodules,there were 60 cases of thyroid papillary carcinoma,one case of follicular carcinoma and two cases of medullary carcinoma.There was significant difference between the strain ratios of the benign and malignant nodules (P<0.05),the ultrasound elastography scores of the benign nodules were statistically different from those of the malignant nodules (P<0.05).The sensitivity,specificity and accuracy of ultrasound elastography were 90.3%,83.2% and 86.9% respectively when used to diagnose the thyroid nodule with the size less than 1 cm.Conclusion Routine ultrasound combined with ultrasound elastography can improve the diagnosis accuracy of small thyroid cancer,and is of great significance in early diagnosis and treatment of thyroid cancer of the pilot.
