The Thyroid Gland01:23

The Thyroid Gland

9.0K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Synthesis and Regulation of Thyroid Hormones

9.3K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Summary

Shear wave velocity (SWV) in thyroid tissue can help differentiate between normal tissue and conditions like chronic autoimmune thyroiditis (CAT) and papillary thyroid carcinoma (PTC). Higher SWV values indicate the presence of fibrosis, a key factor in these thyroid abnormalities.

Area of Science:

  • Medical Imaging
  • Biophysics
  • Pathology

Background:

  • Thyroid lesion characterization is crucial for diagnosis.
  • Acoustic radiation force impulse (ARFI) elastography, measuring shear wave velocity (SWV), shows potential in differentiating tissue types.
  • Fibrosis and cellularity are key pathological features influencing tissue stiffness.

Purpose of the Study:

  • To investigate the correlation between ARFI-generated SWV and the pathological structure of thyroid lesions.
  • To assess the diagnostic value of SWV in distinguishing normal thyroid tissue from chronic autoimmune thyroiditis (CAT), benign nodules, and papillary thyroid carcinoma (PTC).

Main Methods:

  • A total of 599 thyroid tissue samples were analyzed.
  • Samples were categorized into normal thyroid tissue, CAT with fibrosis, benign nodules with high cell density, and PTC with high cell density and fibrosis.
  • Mean SWV was measured for each group using ARFI elastography.

Main Results:

  • Mean SWVs were: normal thyroid (1.60 ± 0.18 m/s), CAT (2.55 ± 0.28 m/s), benign nodules (1.72 ± 0.31 m/s), and PTC (2.66 ± 0.95 m/s).
  • SWV was significantly higher in CAT and PTC compared to normal thyroid tissue (p < 0.001).
  • Fibrosis was identified as a significant factor influencing SWV.

Conclusions:

  • ARFI elastography, through SWV measurements, can effectively differentiate between normal thyroid tissue and pathological conditions like CAT and PTC.
  • Increased SWV is associated with the presence of fibrosis in thyroid lesions, aiding in the characterization of thyroid abnormalities.
