Applicative Value of US-elastograph Imaging in Diagnosis of Thyroid Micro-carcinoma

Objective To evaluate the application of US-elastography in diagnosis of thyroid microcacinoma.Methods The images of color ultrasound and ultrasound elastography from 11 lesions of 10 patients with thyroid micro-carcinoma diagnosed via histopathology between December 2007 and April 2008 were retrospectively analyzed.Results Eight patients with eight lesions were found by colour ultrasound and 10 patients with 10 lesions were observed by ultrasound elastography.The diagnosis accurate rate of ultrasonography was about 72.7% and of ultrasound elastography was about 90.0%.Conclusion US-Elastography is a beneficial addition in diagnosis of thyroid microcacinoma by colour ultrasound.It can remarkably develop the accurate rate of the diagnosis of the disease.
