HT is common in female patients, especially the postpartum women [3]. After the left and right lobes of thyroid and isthmus thyroid were clearly showed at the anterior cross-section, intensity ROI mapping of isthmus was carried on, and mapping region shall not be exceeded the margin on both sides of the trachea, but greater than 1/2 of isthmus gland. Combination with color Doppler flow image or elastography could obtain additional information about the HT and improve the clinical diagnosis. Color Doppler may demonstrate slight to markedly increased vascularity of the thyroid parenchyma. 4cm/s) was higher than that of controls (P=0.026).

At the same time 50 healthy persons without thyroid nodules, cysts or masses, and with negative laboratory examinations, were enrolled as the control group, the male/female rate was 5/45, age was 18-73 y. Two-dimensional and color Doppler flow image were used to examine the thyroid in both groups first, and then GSI of ROI in left lobe, right lobe and isthmus of thyroid were recorded. There are no microcalcifications. Background: Several reports have proposed that increased vascular flow on color Doppler sonography may be associated with malignancy in thyroid nodules.

Scholars found that the formation of blood vessels in the thyroid of patients with HT was due to the free T3 and T4 decrease and increase of thyroid stimulating hormone, which stimulated the thyroid follicular epithelial cells and produced vascular endothelial growth factor. Objective: Grey-scale intensity technology of ultrasound could test the specific quantization of grey-scale intensity of region of interest, which represented the respective characteristics of different pathological tissue changes. In HT group, there were 2 (3.63%) cases with grade G1, 13 (23.63%) cases with grade G2, 32 (58.18%) cases with grade G3 and 8 cases (14.54%) with grade G4.
