Abstract

Background: thyroid gland diseases are common around the world. Diagnosis is usually by
thyroid profile estimation levels. The accuracy of Doppler ultrasonography is accurate and
sensitive in evaluating the gland in detail (size, margins and nodule’s). The indices like peak
systolic volume, pulsatility index and resistive index is useful for diagnosing pathological
thyroid. The aim of the study was to assess the findings of Doppler indices [PSV, PI, RI] of
bilateral superior thyroid arteries [STAs] in normal and pathological thyroid conditions and
use them as reference to evaluate the thyroid status and correlate the USG findings with
thyroid function tests.
Methods: This observational study was conducted between January 2020 and June 2021 at
Vydehi institute of medical sciences. The study consisted of 140 patients divided into two
groups 70 each i.e normal thyroid and pathological thyroid respectively.
Results: The mean age of the pathological group was 44.11± 10.54 years and mean age of
normal group was 42.54± 10.27 years. The study consisted of 27 males and 113 females.
Totally 119 were hypothyroid and 21 were hyperthyroidism. In the pathological group 6 had
low T3 and t4 levels and 17 had increased TSH levels whereas in the normal group 7 had
increased TSH levels. Pathological group the mean PSV was 21.87± 1.20, mean PI was
1.02±0.23 and mean RI was 0.74±0.06. The normal group the mean PSV was 16.4±1.29,
mean PI was 0.91±0.46 and mean RI was 0.54±0.04. The results suggested patients with
increased TSH levels had increased PSV, PI and RI which was significant.
