摘要

To evaluate the vascularity of the thyroid gland in various thyroid dixeases by duplex ultrasound, 13 cases with normal thyroid, 23 of Graves' disease, 5 of follicular adenoma, 14 of other kinds of benign thryoid nodules, and 6 of subacute/Hashimoto's thyroiditis were collected from June through August 1989. The superior thyroid artery was selected to check the peak systolic velocity (PSV) at the point the artery entering the gland. The PSV of normal thyroid gland was 18.8±6.5 cm/sec (mean±standard deviation) for the right lobe, and 22.7±6.4 cm/sec for the left lobe. In Graves' disease, the PSV of the right and left lobes were 74.1±44.7 cm/sec and 71.6±27.2 cm/sec, respectively. In follicular adenoma, the PSVs were 35.4±13.4 cm/sec and 49.8±8.2 cm/sec, respectively. In other benign nodules, they were 30.7±11.8 cm/sec and 36.2±27.6 cm/sec, respectively. In thyroiditis, they were 22±4.1 cm/sec and 28.3±15.3 cm/sec, respectively. As compared wity the normal thyroid gland, the PSV of the superior thyroid arteries in Graves' disease, follicular adenoma, and other benign nodules were significantly higher (p＜0.05). The PSV of the superior thyroid artery in Graves' disease was also signigicantly higher than that in thyroiditis (p＜0.01); this might be valuable in differentiation of the 2 disease (Graves' disease vs thyroiditis) by ultrasound. We concluded that edtermination of the PSV of the superior thyroid arteries by duplex ultrasound, minght be of value in diagnosis of thyroid diseases.
