What echogenic means?
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.
Is echogenic kidneys normal?
Echogenic kidneys can be a normal variant but are also seen in association with renal dysplasia, chromosomal abnormality, adult and fetal polycystic disease, Pearlman syndrome, Beckwith–Wiedemann syndrome, and CMV infection. The incidence of echogenic kidneys has been estimated at 1.6 cases per 1000 sonograms.
Who has been referred to as the father of ultrasound?
Who is Abbe Lazzaro Spallanzani? The “father of ultrasound” he studied how bats use sound waves to detect their victims and to guide their flight. By doing this we can recognize how the ultrasound transmitter utilizes the pulse-echo technique.
How do you treat echogenic focus in left ventricle?
No treatment is required for this condition. The echogenic focus may go away on its own or it may not, but it doesn’t affect a child’s cardiac function so there is no need for treatment or even follow-up testing to see if it is still there.
What causes echogenic focus heart?
An echogenic intracardiac focus (or EIF) is a small bright spot seen on a developing baby’s heart during an ultrasound. The cause of EIF is unknown, but the condition is generally harmless. EIF is considered a normal pregnancy variation, but prenatal screening tests may be desirable to test for any abnormalities.
Can echogenic focus go away?
Will the EIF go away? Most EIF seen in the middle of the pregnancy will not go away before delivery. Since they do not cause problems for the baby, there is no special concern if they are still visible at a later time. For this reason, no ultrasound follow-up is needed to watch for changes in the EIF.
What is the meaning of echogenic focus in left ventricle?
Echogenic foci within the left ventricle of the heart have been found in a minority of fetuses and generally are believed to be a normal variant. Echogenic foci within the left ventricle of the fetal heart represent papillary muscle mineralization.
Does echogenic focus mean Down syndrome?
Conclusion: Fetuses with an echogenic intracardiac focus have a significantly increased risk of Down syndrome. Although most fetuses with this finding are normal, patients carrying fetuses with an echogenic intracardiac focus should be counseled about the increased risk of trisomy 21.

What does a white spot on the baby’s heart mean?
An echogenic intracardiac focus (EIF) is a bright white spot in the fetal heart that looks like a tiny golf ball. This bright spot is due to a bit of calcium in one of the muscles that attaches to the heart valve. It is NOT an abnormality and is NOT associated with heart defects.
What does it mean when a baby has calcium in the heart?
Echogenic intracardiac focus (EIF) is a small bright spot seen in the baby’s heart on an ultrasound exam. This is thought to represent mineralization, or small deposits of calcium, in the muscle of the heart. EIFs are found in about 3–5% of normal pregnancies and cause no health problems.
Is EIF something to worry about?
But echogenic intracardiac focus (EIF) is almost never something to worry about. It shows up as a bright spot on the heart in imaging, and it’s thought to be a microcalcification on the heart muscle. EIF occurs in as many as 5 percent of all pregnancies.
