What does “Echogenic” mean on a radiology report?
Ultrasound word for something that reflects sound strongly and so looks bright on the screen. Describes appearance, not whether something is normal.
How "Echogenic" is used in radiology reports
Ultrasound builds a picture from sound waves that bounce back from tissue. Tissue that reflects a lot of sound looks bright; the word for that is echogenic or hyperechoic. Fat, calcium, gas and fibrous tissue tend to be echogenic. Something that reflects less sound is hypoechoic (darker), and something that reflects almost none, such as clear fluid, is anechoic (black).
You will often see it used in comparisons. An "echogenic liver" means the liver looks brighter than expected, most often because of fat in the liver (hepatic steatosis). An "echogenic focus" is a small bright spot, which can be a tiny calcification. A typical liver haemangioma is a well-defined echogenic spot. In each case, the word describes how the tissue looks on the screen, and the rest of the report says what the radiologist thinks it is.
Echogenicity also depends on the machine settings and the person being scanned, which is one reason ultrasound reports are often cautious and sometimes suggest another type of scan to confirm what something is.

Does this mean something is wrong?
Not on its own. A radiology report describes what the images show, in language written for the doctor who ordered the scan. One term is rarely the whole picture — what it means for you depends on why you were scanned and what else the report says.
If the report worries you, the person who can actually answer that is the doctor who referred you. Understanding the words first usually makes that conversation a better one.
Want your whole report explained?
One term is a start. Radily reads your full report and explains it in plain English — and can talk you through it on video, so you are not reading medical language alone.
Other technical terms
- ArtifactAn abnormal appearance on an image caused by the scanning process, not actual anatomy.
- AttenuationHow much X-rays are absorbed by tissue. Dense tissue (bone) shows high attenuation (bright), while air shows low attenuation (dark).
- AxialCross-sectional images taken in a horizontal plane, like slicing bread.
- ContrastA dye injected or swallowed to make certain tissues show up better on imaging.
- CoronalImages taken from front to back, dividing the body into front and back portions.
- DensityHow solid or compact tissue appears on imaging. High density = bright (bone), low density = dark (air).
