Objective To observe the regularity of contrast agent perfusion in hyperthyroidism, hypothyroidism and normal thyroid function with contrast-enhanced ultrasound imaging. Methods Forty five patients with hyperthyroidism, hypothyroidism and normal thyroid function were selected. The peak flow velocity of the left superior thyroid artery was measured by conventional color ultrasound. The dynamic images were recorded by contrast-enhanced ultrasound. The arrival time and peak intensity of the left thyroid artery and vein were measured. The inner diameter and flow rate of the superior thyroid artery in hyperthyroidism, hypothyroidism and normal thyroid function. Results The PSV of the superior thyroid artery in the hyperthyroidism group and hypothyroidism group measured by conventional color ultrasound was significantly higher than that in the normal control group (P. There was no significant difference in the diameter and peak intensity of the superior thyroid artery among the three groups. Conclusion The preliminary results of this study suggest that contrast-enhanced ultrasound shows hyperthyroidism, hypothyroidism and normal thyroid perfusion have certain rules, and the parameters of contrast-enhanced ultrasound can provide important information on the changes of thyroid hormone levels.
