Ultrasound Assessment for Thyroid Examination in Patients with Hypothyroidism

Abstract

Patients with overt hypothyroidism show decreased echogenicity of the thyroid at ultrasonography . The purpose of the present study was to evaluate the effectiveness of ultrasonography for diagnosing the most common hypothyroidism and to guide patients to appropriate treatment show decreased echogenicity of the thyroid by ultrasonography. This study have been conducted on 80Patients, the age group between 20-70 years, in the period of January 2020 to October 2021. Thyroid ultrasonography was carried out by the type of ultrasound (US) machine used in the study is a sameness -X300 ultrasound device with 7.5MHz probe. The volume of the thyroid lobe noticed calculations according to the formula of the: width x length x thickness. The assessment of the 80 patients with hypothyroidism who were included in our study, (57) patients with decreased echogenicity, 23 patients had been with normal echogenicity, the lowest was found in patients homogenous enhancement 42.5%, non- homogenous 57.5%, thyroid the gland has a medium gray scale homogeneous echo pattern and the level of echogenicity is higher than Size of thyroid, The higher percentage of nodules (51.3%) of the size of the thyroid was normal. But the higher percentage of nodules type (40.0%) for the study group was solid compared to the lower percentage (2.5%) was solid and cystic. Ultrasound had high specificity and more accuracy to assess patients with hypothyroidism. An association between hypo echogenicity at thyroid US and high level of thyroid stimulation hormone (TSH suggesting decreased echogenicity at the ultrasonography diagnostic.
