What does echogenic mean in ultrasound?

Echogenicity. Echogenicity of the tissue refers to the ability to reflect or transmit US waves in the context of surrounding tissues. Based on echogenicity, a structure can be characterized as hyperechoic (white on the screen), hypoechoic (gray on the screen) and anechoic (black on the screen) [Figure 1].

What causes echogenicity?

One of the known reasons for echogenic bowel is an early bleed in the pregnancy (which you may not have been aware of). Echogenic bowel may be caused by the baby swallowing some blood in the amniotic fluid. This is not harmful to the baby. Echogenic bowel can be associated with cystic fibrosis.

What are echogenic areas?

Areas. of increased echogenicity in the fetal abdomen are defined as ab- normally bright areas with an echogenicity similar to that of surround- ing bones. Such areas are encountered in various normal and abnormal processes.

What is the difference between hyperechoic and echogenic?

As adjectives the difference between echogenic and hyperechoic. is that echogenic is (medical) describing any inner part of the body that reflects sound waves and thus produces echos that may be detected using ultrasound scanners while hyperechoic is of high echogenicity.

What does echogenic lesion mean?

According to the ultrasonography lexicon of the Breast Imaging-Reporting and Data System of the American College of Radiology,(1) an echogenic breast lesion is defined as a lesion that is hyperechoic in comparison to the surrounding subcutaneous adipose tissue on ultrasonography.

What does increased echogenicity mean on ultrasound?

In other words, echogenicity is higher when the surface bouncing the sound echo reflects increased sound waves. Tissues that have higher echogenicity are called “hyperechogenic” and are usually represented with lighter colors on images in medical ultrasonography.

What does echogenic cyst mean?

These echogenic foci are small hairs floating in the cystic fluid. Tip of the iceberg sign; the appearance of a hyperechoic area, the base of which cannot be visualised. This is the result of a mass made up of matted hair and sebum casting an echogenic shadow.

Are echogenic masses cancerous?

An echogenic mass in an ectatic duct warrants biopsy to exclude carcinoma. An echogenic skin lesion is most likely benign and can occasionally have peripheral vascularity due to surrounding inflammation. However, a skin lesion with internal vascularity is concerning for metastasis or lymphoma.
