Ultrasound – Questions and Answers

The ultrasound or ultrasound exam is well known for its function of monitoring pregnancy and the baby’s development. However, it is not the first test to be done when you are pregnant, since the first is a blood test and you cannot even answer all the information regarding the health of the woman and the child. Learn more about the possibilities of ultrasound in pregnancy.

How to Know the Day I Got Pregnant by Ultrasound?

The ultrasound done until the 13th or 14th week of pregnancy helps doctors calculate the baby’s gestational age by the size of the baby, that is, how long she has been pregnant. Knowing the right period in which you got pregnant, however, is not possible by ultrasound. Only by calculating the woman herself in relation to her cycle and fertile period is it possible to indicate the approximate week that the pregnancy happened. After the first trimester , ultrasound is no longer used to calculate gestational age, because the size of the fetuses can vary from one to another.

How to Know the Baby’s Size on Ultrasound?

The calculation performed to know the baby’s measurements is done through the size of the femur that is shown in the ultrasound exam, it is possible to calculate the approximate size of the baby in centimeters, multiplying this number by 7.

How to Know Who the Father Is by Ultrasound?

There is no way to know who the child’s father is by ultrasound, only by DNA examination .

3D Ultrasound: When to Do?

Normal ultrasound is usually sufficient as a routine examination in pregnancy . But 3D ultrasound can also be performed, which has greater definition and allows you to see the baby’s skin, being useful for identifying problems such as cleft lip , as well as assessing and measuring organ volumes, such as the heart.

4D Ultrasound: When to do it?

The 4D ultrasound shows the baby moving in real time, and the best images can be captured between the 26th and 30th weeks of pregnancy . It is a more expensive exam that most health insurance plans do not cover.

Where to do the ultrasound

The morphological ultrasound examination can be done in some hospitals and laboratories with specialized diagnostic imaging services. Both in the private network and in the public network, the exam is scheduled by appointment.

What to Eat for the Baby Touching the Ultrasound?

For the baby to perform on ultrasound, the mother just needs to drink a cold fruit juice 30 minutes before the exam, which helps to “wake up” the baby with the sugar and ice cream, or ingest chocolate that usually “shakes”. Eating any meal can also make your baby more agitated.

Ultrasound 4 Weeks: What Can You See?

In the 4-week ultrasound, it is still too early to see anything, it is only possible to see the gestational sac, as the fetus is still too small to appear clearly.

Pelvic Ultrasound: How It Is Done

Pelvic ultrasound is done with the ultrasound device leaning against the lower abdomen wall, with the patient having a full bladder, to differentiate her from the uterus. Therefore, it is recommended to be without urinating for at least 2 hours before the exam, and to drink 4 to 8 glasses during this period.

Total Abdomen Ultrasound: What Do You See?

Ultrasound of the total abdomen needs 4 hours of fasting, because it also sees the gallbladder that needs to be empty. The test evaluates solid or fluid-filled organs, as the gas reflects the ultrasound waves, so the stomach and intestine cannot be seen. The organs are: pancreas, aorta, liver, gallbladder, kidneys, spleen and bladder (full).

What does “CC” Mean on Ultrasound?

In the morphological ultrasound exam , CC (head circumference) measures the baby’s head, being able to assess if there is any asymmetry or “flatness”.

What is “DBP” in Ultrasound?

In the ultrasound exam, BPD (biparietal diameter) is the measurement of the baby’s head, being the distance between the parietal bones (the sides) of the skull.

What Does “EDD” Mean On Ultrasound?

EDD on Ultrasound means an estimate for the expected date of delivery, and may change slightly between exams. EDD stands for Expected Date of Delivery in English (Expected Date of Delivery).

What does “CA” Mean on Ultrasound?

In the ultrasound exam, CA (abdominal circumference) assesses the baby’s intrauterine growth, whether it is being asymmetrical or slow.

How to Detect Down Syndrome on Ultrasound?

The ultrasound shows the measurement of the baby ‘s nuchal translucency , and from it one can suspect, if it is beyond normality, of risks for genetic syndromes such as Down’s Syndrome. This is confirmed with amniocentesis and other tests.
