Mar 15, 2025 · The thyroid gland is a single midline endocrine organ in the anterior neck responsible for thyroid hormone production. It lies in the visceral space, completely enveloped by the pretracheal fascia (the middle layer of the deep cervical fascia).

Apr 19, 2022 · On ultrasound, the normal thyroid gland has a homogeneous (smooth/uniform), medium- to high-level echogenicity (brightness level). Key landmarks include the trachea, esophagus, blood vessels (carotid arteries and jugular vein), and surrounding muscle groups. The size and shape of the thyroid lobes vary widely in the normal population.

Jan 11, 2025 · Ultrasound is the first-line imaging modality for assessment of thyroid nodules found on clinical examination or incidentally on another imaging modality. This article is an overview of ultrasonographic features of thyroid nodules, which are used to determine the need for biopsy with fine needle aspiration (FNA).

Feb 27, 2020 · What is a thyroid ultrasound? An ultrasound is a painless procedure that uses sound waves to generate images of the inside of your body. Your doctor will often use an ultrasound to create images...

Thyroid sonography should be performed in all patients with known or suspected thyroid nodules. MNG’s US should be performed.......... 1. 2. 3. 4. Diagnostic tests require high sensitivity!!

High-resolution ultrasonography (USG) is the most sensitive imaging modality available for examination of the thyroid gland and associated abnormalities. Ultrasound scanning is non-invasive, widely available, less expensive, and does not use any ionizing radiation.

Thyroid ultrasound uses sound waves to produce pictures of the thyroid gland within the neck. It does not use ionizing radiation and is commonly used to evaluate lumps or nodules found during a routine physical or other imaging exam. This procedure requires little to no special preparation.

Apr 11, 2020 · Thyroid ultrasonography (US) is the most common, extremely useful, safe, and cost-effective way to image the thyroid gland and its pathology. US has largely replaced the need for thyroid scintigraphy except to detect iodine-avid thyroid metastases after thyroidectomy and to identify hyper-functioning (toxic) thyroid nodules.

Patients with multinodular goitre (MNG) are most commonly clinically euthyroid but may be hyperthyroid or borderline with suppressed thyroid‐stimulating hormone (TSH) levels but normal free T 4 and T 3. It is the most common cause of tracheal/oesophageal compression and may even be the cause of laryngeal palsy. 1.

Dec 29, 2024 · Ultrasound (US) followed by USG-FNA is paramount for the evaluation of thyroid nodules. This chapter covers the US of normal thyroid gland, thyroid gland anomalies, and thyroid nodules including US features that prompt FNA cytology correlation. USG-FNA techniques for sampling thyroid nodules and specimen handling are also included.
