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.

Introduction: The role of Color Doppler USG and MRA in the evaluation of extracranial carotid arteries in stroke patients and to detect the atherosclerotic plaque and to characterize the atherosclerotic plaque with the help of Doppler ultrasound and MRA is described in this purpose of study.




Materials and Methods: NASCET Grading of percentage of stenosis, Doppler ultrasound was done and compared with MR Angiography TOF sequence and IV contrast in detection of plaque, plaque characterization and percentage of stenosis.



Results: Males are seen to be affected grossly more than females. Systemic hypertension is found to be the most common risk factor associated with stroke and the least was found to be ischemic heart disease. The right side is seen to be more commonly affected by atheromatous plaque followed by left side, with less bilateral involvement. ICA was found to be the most commonly involved site. Most of the cases had no significant stenosis, only few cases showed significant stenosis with hemodynamic changes. Homogenous soft plaques were found to be common than calcified and ulcerated plaques.
Conclusion: Both modalities of ultrasound and MR Angiography the advantage of endarterectomy in symptomatic patients is clearly seen with more percentage of stenosis.  In combination with MRI, Doppler USG has shown to be a safer, non-invasive and precise way of diagnosing and measuring an extracranial component of carotid disease and thereby helping to accurately treat it.
