Morphological ultrasound of the 2nd trimester (20-22 weeks)

Home Ginecologia

Detailed examination of anatomy

The morphological ultrasound of the second trimester is one of the most important of the entire pregnancy. Performed between the 20 and 22 weeks, it is the phase when the baby is already more developed, allowing a much more detailed analysis of its anatomy, growth, and well-being than in previous ultrasounds.

How is the second-trimester ultrasound done? 

The ultrasound is performed non-invasively through a transabdominal examination. The procedure is quick, painless, and safe for both the mother and the baby. 

The duration of the examination may vary depending on the baby's position and the need for detailed measurements. 

Why is it important? 

It is essential to confirm that the baby is developing correctly. It allows for the early detection of potential structural problems and helps monitor the baby's growth, ensuring proper care throughout the rest of the pregnancy.

Right moment

When this ultrasound is performed

This examination takes place between the 20 and 22 weeks of gestation, because it is the period when the baby has sufficient anatomical development to allow for a detailed evaluation of organs and structures, without being too large to hinder visualization.
Doubts about gestational age?

If you have doubts about your exact gestational age or when to schedule this examination, our gynecology and obstetrics team can clarify them in a routine consultation.
