Abstract
Thyroid blood flow as it relates with thyroid function is important in diagnosing throid gland disease. However, there have been no reports on such observations of thyroid artery flow, especially quantitatively. In this study, a newly developed high frequency Ultrasound Duplex Scanner we used to analyze superior thyroid artery flow dynamics. In all 16 healthy controls, we observed superior thyroid arteries. The diameter of the superior thyroid arteries was 0.14±0.04cm (mean±SD), the average blood flow speed was 3.8±2.9cm/sec (mean±SD), and the blood flow volume was 2.25±3.09ml/min (mean±SD). Diseased side superior thyroid artery blood flow volume of solitary thyroid adenoma and papillary carcinoma increased noticeably compared with healthy controls. Three of hour cases of adenomatous goiter showe increased bilateral blood flow. In subacute thyroiditis, there was no blood flow increase on any side. These data suggest that the measurement of superior thyroid artery blood flow is important to diagnose thyroid gland carcinoma.
