Abstract
Objective: To evaluate if the vascularization patterns in the thyroid gland parenchyma by the conventional ultrasound mode
B, and color Doppler ultrasonography correlated with the peak systolic velocity (PSV) of the inferior thyroid artery using
pulsed Doppler in patients with Hashimoto’s thyroiditis (HT) in various stages. Methods: Patients with diagnosis of HT were
enrolled in this prospective study in the period two years. Thyroid glands of all patients were evaluated with conventional
ultrasound mode B, color-flow Doppler ultrasonography, and peak systolic velocity (PSV) of the inferior thyroid artery. Data
were analyzed applying variance (ANOVA) and Pearson’s or Spearman’s correlation. Results: A hundred twenty patients (10
men and 110 women) were included in the study. Highly elevated PSV were associated with very lower thyroid echogenicity
and heterogeneous pattern thyroid gland (p= 0.01) and intrathyroidal blood flow (p= 0.004). Conclusions: We conclude that
evaluation the vascularization patterns of the thyroid gland parenchyma in patients with HT when compared to conventional
ultrasound mode B, and with the PSV of the inferior thyroid artery by pulsed Doppler showed a high correlation. Probably
this method could be recommend as a measure of thyroid blood flow as an essential part of evaluating ultrasonography in
the HT.
