What does it mean when your thyroid is heterogeneous?
Heterogeneous echogenicity of the thyroid gland is a non-specific finding and is associated with conditions diffusely affecting the thyroid gland. These include: Hashimoto thyroiditis. Graves disease.
What does homogeneous echogenicity mean?
Normal liver echogenicity is homogeneous, with fine echoes. 1 One of the main causes of heterogeneous echogenicity of the liver is chronic liver disease/cirrhosis (Figure 1 of the supplementary material). Other common conditions leading to heterogeneous echogenicity are patchy steatosis and diffuse tumor infiltration.
What is normal thyroid size?
Normal thyroid lobe dimensions change from birth into adulthood: the length (L or craniocaudal) diameter is 1.8 to 2.0 cm in newborns and 4.0 to 6.0 cm in adults, while the A-P dimension measures 0.8 to 0.9 cm in newborns and 1.3 to 1.8 cm in adults.
What does heterogeneous parenchyma mean?
Specifically, the thyroid parenchyma was evaluated for the presence or absence of diffuse hypoechoic echogenicity (defined as diffuse decreased parenchymal echogenicity compared with adjacent strap muscles), parenchymal heterogeneity (defined as coarse echotexture with areas of mixed echogenicity involving >50% gland …
Is a heterogeneous thyroid bad?
Heterogeneous echogenicity of the thyroid gland has been associated with diffuse thyroid disease and benign and malignant nodules can coexist with diffuse thyroid disease. Underlying heterogeneous echogenicity might make it difficult to differentiate between benign and malignant nodules on US.
What does heterogeneous appearance mean?
Heterogeneous is a word pathologists use to describe tissue that looks very different from one area of the tissue to the next. Differences in colour, shape, and size can make a tissue look heterogeneous. Heterogeneous can be used to describe the way the tissue looks with or without a microscope.
What does homogeneous mean in ultrasound?
• Homogeneous: organ parenchyma is uniform in echogenicity (Figure 1-4). • Inhomogeneous or heterogeneous: organ parenchyma is not uniform in echogenicity (Figure 1-5). Ultrasound Artifacts.
What is a homogeneous disease?
The word is used as an opposition to homogeneous, meaning that given a group of patients, the disease is the same for all of them. When a condition is heterogeneous, it is normally divided in endotypes.
What is a homogeneous mass?
A mass that exhibits essentially the same physical properties at every point throughout the mass.
What is a homogeneous relationship?
From Wikipedia, the free encyclopedia. In mathematics, a homogeneous relation (also called endorelation) over a set X is a binary relation over X and itself, i.e. it is a subset of the Cartesian product X × X. It is also simply called a (binary) relation over X.
What is the difference between homogeneous and homogeneous?
Is it homogeneous or homogenous? Homogenous is an older scientific term that describes similar tissues or organs. It has been replaced by homologous. Homogeneous is an adjective that describes similar or uniform characteristics.
How do you distinguish between homogeneous and heterogeneous mixtures?
The prefixes: “hetero”- indicate difference. A homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly referred to as solutions. A heterogeneous mixture consists of visibly different substances or phases.
What is a famous homogeneous catalyst?
Some examples of homogeneous catalysts are brønsted and Lewis acids, transition metals, organometallic complexes, organocatalyst. Some notable chemical processes that occur through homogeneous catalysis are carbonylation, oxidation, hydrocyanation, metathesis, and hydrogenation.
What is homogeneous reduction?
Catalysts that have been explored include homogeneous catalysts in solution, catalysts immobilized on surfaces, and heterogeneous catalysts. In homogeneous catalysis, reduction occurs following diffusion of the catalyst to an electrode where multiple proton coupled electron transfer reduction occurs.
