Second Trimester Morphological
Thorough Assessment of Baby Development
What is a morphological exam?
Morphological exams are more detailed tests because we study the morphology (shape and size) of the organs, that is, we closely examine whether that organ has the appropriate shape and whether its size is within the expected range for the gestational age.
Why is he so important?
The second trimester morphological ultrasound is crucial for detailed assessment of the baby's organ development, identifying possible structural abnormalities. Some malformations can be treated surgically while still in the womb, so early diagnosis is essential. It is an essential exam to ensure the health and well-being of the pregnant woman.action.
When should it be done?
It should be done, preferably, between 22 and 24 weeksIt is a period when the baby is larger so that we can evaluate in more detail organs that were very small at the time of the first trimester morphological scan, such as the heart and brain. In obese patients, it can be done later, between 25 and 26 weeks.
What are the benefits?
Check the development of organs such as the brain, heart, kidneys, and spine, as well as limbs. Detects malformations and conditions that can be treated early or monitored more closely during pregnancy. Confirm
the healthy development of the baby and provides security for the mother and the family.
Which tests can be associated with it?
THE Doppler of the Uterine Arteries It is essential to assess whether the placenta is able to receive blood from the mother without difficulty.
Measure of Cervical Collar: through the measure, we see if the mother has an increased risk of preterm birth.
Frequently Asked Questions - FAQ -
Is any preparation needed?
Fasting or a full bladder is not necessary. We ask that mothers avoid applying oils on their abdomen for 2 days before the exam, as oil interferes with image acquisition.
And don't go on an empty stomach 🙂
Why measure the cervix?
The measurement of the cervix helps identify risks of preterm labor. If the
colo for short (<2.5 cm), the obstetrician can recommend preventive treatments, such as the use of progesterone or cerclage.
What is the Doppler of the uterine arteries and why is it important?
Doppler assesses blood flow in the uterine arteries. If your flow encounters resistance reaching the uterus, it increases the mother's risk of developing conditions
as preeclampsia and early fetal growth restriction (<32 weeks). If they are
If altered, the obstetrician can administer their own medications to reduce these risks, such as aspirin and calcium.
Can I find out the baby's gender with this test?
Yes, most babies show their sex in this exam. Very difficult to get a no

How long does the second trimester morphological ultrasound last?
There is no fixed time, as the doctor depends entirely from the position
from the baby and the need for additional assessments. Take your time and don't schedule.
appointments right after.
THE morphological excludes the need to perform the echocardiogram?
No, they are different exams. The morphological ultrasound assesses the basic anatomy of the heart, while the fetal echocardiogram focuses on function, blood flow, and heart valves.
Do I need a doctor's prescription to take the exam?
Yes, the morphological ultrasound is usually requested by the obstetrician, as it is one of the main ones during pregnancy.
It is possible to detect all What are the baby's conditions with the morphological ultrasound?
Although the exam is more detailed, it is not capable of detecting 100% of genetic changes or anomalies. Some conditions may require additional tests, such as genetic testing, and a small percentage of babies with normal ultrasounds will have some syndrome or malformation diagnosed after birth (1:800).
Is the exam done with 3D imaging?
Three-dimensional images are not part of the examination or prenatal care. It's an "extra".
a "plus" from the examining doctor. As long as the baby is in a favorable position and
The ultrasound machine has a 3D probe installed.
What can be seen?
Most of the time...
Vertebral Column. Important assessment to rule out defects
closure.
Assessment of the main arteries of the fetal abdomen.
Mouth and nose region. Assess if the baby has cleft lips.
Assessment of both hands to count the 10 fingers.
Facial profile, we assess the presence and measurement of the nasal bone and some brain structures.
