Study of Color Doppler Flow Imaging and VEGF in Thyroid Tumours / 医疗卫生装备

Objective To investigate the expression of vascular endothelial growth factor(VEGF) and Color Doppler flow imaging in human thyroid tumours. Methods 90 cases of thyroid tumours were examined for VEGF expression by means of immunohistochemistry and were examined with color Doppler ultrasound for blood flow. Results The positive rates of VEGF expression were much higher in thyroid carcinomas than that in thyroid adenomas. The difference was significant( P
