Table of Contents
What is homogeneous echogenicity?
Homogeneous echogenic echopattem The appearance is of a compact mesh of fine scattered echoes of uniform dis- tribution and amplitude.
What causes heterogeneous echogenicity?
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.
Is a homogeneous thyroid normal?
Echogenicity is another important feature to be analyzed in thyroid nodules. The normal thyroid tissue is homogeneously hyperechoic and brighter than the surrounding muscles.
What does it mean when the liver homogeneous in echogenicity?
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.
Is a homogeneous liver normal?
The liver has homogeneous parenchyma with medium level echogenicity and straight hepatic surface as normal characteristics (Fig.
What does homogeneous mean medically?
Medical Definition of homogeneous : of uniform structure or composition throughout.
What does homogeneous mean in radiology?
A homogeneous x-ray beam can be defined as a beam that contains photon of only one energy as compared to heterogeneous x-ray beam containing several photons of energies1. When a homogeneous x-ray beam passes through a medium, its intensity falls exponentially with the distance covered.
What does homogeneous echogenicity of the liver mean?
What does homogeneous mean in CT scan?
Heterogeneous refers to a structure with dissimilar components or elements, appearing irregular or variegated. For example, a dermoid cyst has heterogeneous attenuation on CT. It is the antonym for homogeneous, meaning a structure with similar components. Heterogenous refers to a structure having a foreign origin.
Is a fatty liver homogeneous?
The radiologic features of fatty liver disease stem from the increased fat content of the liver parenchyma. The spatial pattern may be diffuse and homogeneous or heterogeneous, with focal fat deposition in an otherwise normal liver or areas of focal fat sparing in a diffusely fatty liver.
What is a homogeneous mass?
A mass that exhibits essentially the same physical properties at every point throughout the mass.
What causes homogeneous liver?
The most common cause of hyperechogenic liver (increased liver echogenicity compared with the renal cortex) in routine practice is steatosis, otherwise known as “fatty liver”. This can be either diffuse or focal.
What is a echogenicity in medical terms?
Echogenicity (misspelled sometimes as echogenecity) or echogeneity is the ability to bounce an echo, e.g. return the signal in ultrasound examinations. In other words, echogenicity is higher when the surface bouncing the sound echo reflects increased sound waves.
