What is Detailed Ultrasound and How is it Performed?

Ultrasound is a diagnostic imaging technique that uses high-frequency sound waves to create images of internal organs and tissues. Detailed ultrasound, also known as a targeted or level 2 ultrasound, is a more comprehensive ultrasound examination that is typically performed during pregnancy. In this article, we will explore what detailed ultrasound is, what structures can be examined, how it is performed, when it is performed, and its reliability.

What is Detailed Ultrasound?

Detailed ultrasound is an ultrasound examination that is performed during pregnancy to evaluate the health and development of the fetus. It is typically performed during the second trimester, between 18 and 22 weeks of gestation. This ultrasound is called “detailed” because it provides a more detailed and comprehensive evaluation of the fetus than a standard ultrasound.

What are the Situations in Which Detailed Ultrasound is Applied to Pregnant Women?

Detailed ultrasound is typically recommended for pregnant women who are at high risk of complications, such as those with a history of preterm labor, fetal growth restriction, multiple gestation, or a suspected fetal abnormality. It may also be recommended for women who are carrying a high-risk pregnancy due to their age, medical history, or other factors.

Which Structures Can be Examined with Detailed Ultrasound?

Detailed ultrasound can evaluate many aspects of the fetus’s health and development, including:

Brain

Detailed ultrasound can evaluate the structure and function of the fetal brain, including the presence of any abnormalities.

Spine

Detailed ultrasound can evaluate the fetal spine for any abnormalities or defects.

Heart

Detailed ultrasound can evaluate the structure and function of the fetal heart, including the presence of any defects or abnormalities.

Limbs

Detailed ultrasound can evaluate the fetal limbs for any abnormalities or defects.

Kidneys

Detailed ultrasound can evaluate the fetal kidneys for any abnormalities or defects.

Face

Detailed ultrasound can evaluate the fetal face for any abnormalities or defects.

Umbilical Cord and Placenta

Detailed ultrasound can evaluate the umbilical cord and placenta for any abnormalities or defects.

How to Perform Detailed Ultrasound in Pregnancy?

Detailed ultrasound is typically performed by a trained sonographer or obstetrician in a hospital or clinic setting. The examination is performed using a transducer, which is a small handheld device that emits high-frequency sound waves. The transducer is placed on the pregnant woman’s abdomen, and the sound waves bounce off the internal organs and tissues to create images of the fetus.

During the examination, the sonographer or obstetrician will evaluate the fetus for any abnormalities or defects. They will measure the fetus’s head, abdomen, and femur to estimate its size and growth. They will also evaluate the amniotic fluid volume, umbilical cord, and placenta.

When is Detailed Ultrasound Performed?

Detailed ultrasound is typically performed between 18 and 22 weeks of gestation. This is because most fetal abnormalities are detectable by this time. However, in some cases, a detailed ultrasound may be performed earlier or later in the pregnancy, depending on the specific situation.

How Many Hours Does a Detailed Ultrasound Take?

A detailed ultrasound typically takes between 30 and 60 minutes to complete. However, the exact time can vary depending on the specific situation and the fetus’s position.

Is Detailed Ultrasound Reliable During Pregnancy?

Detailed ultrasound is a highly reliable diagnostic tool for evaluating the health and development of the fetus during pregnancy. However, it is important to remember that no diagnostic test is 100% accurate, and there is always a small risk of a false-positive or false-negative result.

FAQs

Q1. Can Detailed Ultrasound Harm the Fetus?

No, detailed ultrasound is considered a safe and non-invasive diagnostic.

Q2. Can Detailed Ultrasound Determine the Sex of the Fetus?

Yes, a detailed ultrasound can often determine the sex of the fetus. However, this is not always the case, as the position of the fetus and other factors can make it difficult to see the genital area.

Q3. How is Detailed Ultrasound Different from a Standard Ultrasound?

Detailed ultrasound is a more comprehensive ultrasound examination than a standard ultrasound. While a standard ultrasound is typically performed during the first trimester to confirm the pregnancy and estimate the gestational age, a detailed ultrasound is typically performed during the second trimester to evaluate the health and development of the fetus in more detail.

Q4. Is Detailed Ultrasound Covered by Insurance?

Most health insurance plans cover the cost of a detailed ultrasound if it is deemed medically necessary. However, it is always a good idea to check with your insurance provider beforehand to confirm coverage and any potential out-of-pocket costs.

Q5. What Happens if Abnormalities are Detected During a Detailed Ultrasound?

If abnormalities are detected during a detailed ultrasound, further testing or monitoring may be recommended to evaluate the severity of the condition and develop an appropriate treatment plan. This may include additional ultrasounds, blood tests, genetic testing, or referrals to specialists.

Conclusion

Detailed ultrasound is a valuable diagnostic tool for evaluating the health and development of the fetus during pregnancy. It can provide a comprehensive evaluation of many aspects of the fetus’s health, including the brain, spine, heart, limbs, kidneys, face, umbilical cord, and placenta. While the examination is typically performed during the second trimester, it may be recommended earlier or later in the pregnancy depending on the specific situation. If you have any concerns about your pregnancy or the health of your fetus, be sure to talk to your healthcare provider.
