 Hashimoto's thyroiditis, HT, is the most common form of thyroiditis in childhood. Shear-wave elastography, SWE, is a non-invasive imaging technique used to measure the stiffness of the thyroid gland. This study found that SWE values are higher in patients with HT compared to healthy controls. Additionally, the study found that age, BMI standard deviation score, and antithyroid peroxidase levels are associated with increased SWE values.
