“…In addition, no common guidelines exist on how to obtain these parameters ()()(29-31). Mahmutyazicioglu and Turgut compared 20 children with normal thyroids, with 20 children with endemic goiter and found that RI values were significantly lower in the disease group (32). The mean RI was 0.58±0.05 in the disease group and 0.70±0.05 in the control group.…”

OBJECTIVE:The role of Doppler ultrasonography in the diagnosis of diffuse thyroid diseases is not well established. In particular, Doppler ultrasonography findings in children with Hashimoto's thyroiditis are very limited. We examined gray-scale and Doppler ultrasound findings in Hashimoto's thyroiditis in children in an attempt to understand the feasibility of future prospective controlled studies.MATERIALS AND METHODS:Twenty-one children with newly diagnosed Hashimoto's thyroiditis were recruited in the study. The patients were euthyroid or had subclinical hypothyroidism at the time of the ultrasonography examination. According to the color Doppler scale developed by Schulz et al., thyroid glands were classified into four patterns based on visual scoring and the mean resistive index (RI), which was calculated via measurements from both lobes, and these results were compared with gray-scale findings.RESULTS:The mean RI value, calculated as the mean of the RI values of both lobes obtained from each patient, was found to be 0.57±0.05 (range 0.48-0.67) cm/sn. The distribution of thyroid classifications was as follows: Pattern 0, n = 7; Pattern I, n = 6; Pattern II, n = 4; and Pattern III (“thyroid inferno”), n = 4. The mean RI values in patients with normal or near-normal gray-scale findings (n = 10) and patients with more substantial gray-scale changes (n = 11) were not significantly different and were lower than the values in normal children previously presented in the literature.CONCLUSION:The results indicated that the RI may be more sensitive than other ultrasound parameters for the diagnosis of Hashimoto's thyroiditis.

“…There are controversial reports in the literature about the relation between thyroid blood flow changes and thyroid hormone levels (Bogazzi et al 1999;Saleh et al 2002;Mahmutyazicioglu and Turgut 2004;Kumar et al 2009). No correlations were detected between thyroid hormones and TV and Doppler parameters in the present study.…”

The aim of the present study was to determine alterations in thyroid blood flow parameters and thyroid volume (TV), measured at inferior thyroid artery (ITA), due to changes in sex hormones and thyroid stimulating hormone (TSH) at four different periods of menstrual cycle (MC) showing infradian rhythm in healthy women. Twenty-two women with regular MC were recruited. Individuals were assessed with hormone levels, and Doppler ultrasound (US) findings at days 3, 7, 14, and 21 of MC. Mean TSH, peak systolic velocity (PSV), resistance index (RI), pulsatile index (PI), and TV were statistically analyzed. Compared to days 3 and 7, significant increases were detected in TSH, TV, and PSV at day 14 (p ¼ 0.005, p ¼ 0.000, p ¼ 0.014; and p ¼ 0.021, p ¼ 0.002, p ¼ 0.021, respectively). No significant differences were found for PI at different periods of MC (p 4 0.05). RI significantly decreased at days 14 and 21 when compared to day 3 (p ¼ 0.020 and p ¼ 0.015, respectively). Alterations occur in ITA blood flow parameters and TV along with TSH levels throughout the MC.

Doppler evaluation of the thyroid in pediatric goiter

Abstract: In the arteries supplying the thyroid gland in a pediatric population, RIs were lower and PSVs higher in the patients with diffuse goiter than in the healthy control group. We discuss iodine deficiency as a possible mechanism for these changes.
