Objective: To evaluate the role of thyroid blood flow assessment by color-flow Doppler ultrasonography in the differential diagnosis of thyrotoxicosis.
Methods: Consecutive patients with thyrotoxicosis presenting to our center between June 2007 and March 2008 were included in the study. Clinical data were collected, and thyroid function tests including measurements of thyrotropin, total thyroxine, and total triiodothyronine were performed.
