What causes heterogeneous echogenicity?
Heterogeneous echogenicity of the thyroid gland has been associated with diffuse thyroid disease (DTD) including Hashimoto thyroiditis (HT) and Graves’ disease [1-4].
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 heterogeneous in ultrasound?
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.
Does heterogeneous thyroid mean cancer?
Background: 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.
Are fibroids heterogeneous?
What are the radiological findings of fibroids? On ultrasound fibroids are heterogeneous, hypoechoic (which means dark), solid masses. Uterus is enlarged. Fibroid often calcify.
What does it mean by heterogeneous uterus?
The heterogeneous appearance of the myometrium includes uterine enlargement and asymmetry of the anterior or posterior myometrial wall.
What is the meaning of homogeneous echotexture?
Beside above, what is homogeneous in Echotexture? Answered Jul 22, 2018. When scanned using an ultrasound probe, homogenous echotexture means the liver tissue appear uniform on the reflected sound waves. This could mean the liver is entirely normal or entirely abnormal. Subsequently, one may also ask, what does homogeneous myometrium mean?
What is mixed echogenicity?
mix echogenicity means on ultrasound it looks like a lot of different things. so it is not what tells there is not cancer there. mix echogenicity can come from scar tissue in the area or blood from hematoma causing different signals in the area.
What does low echogenicity mean?
In very general, decreased echogeneicity means the material produces less echoes when it is hit by a sound wave. There can be numerous causes for this, either due to the material itself (less acoustic impedance mismatch with surroundings), the surroundings, through which the wave passes before reaching…
What does echogenicity mean in the uterus?
In the uterus, the echogenicity of the myometrium remains constant throughout the menstrual cycle and following various hormonal treatments. In contrast, the echogenicity of the endometrium varies between the follicular and luteal phases of the menstrual cycle and in response to exogenous hormones.
