Which organ's echogenicity is described as moderately echogenic and can reflect changes in fetal growth?

• A. Liver
• B. Heart
• C. Spleen
• D. Kidneys

Answer: (A)

Echogenicity refers to how bright an organ appears on ultrasound. The fetal liver normally presents a mid-level, moderate echogenicity, meaning it is neither very bright nor very dark compared with surrounding tissues. This consistent, measurable brightness makes the liver a useful reference for assessing overall fetal growth and maturation because changes in gestational age and growth can subtly alter its appearance and size. When growth is affected, the liver’s echogenicity or size may shift in detectable ways, helping clinicians gauge fetal growth status. Other organs may have different typical brightness or be influenced by factors that aren’t as directly tied to overall growth, so they aren’t as reliable for this purpose.
