Morphological Ultrasound

20 week morphological ultrasound

The second-trimester morphology is the main ultrasound of your pregnancy, during which a rigorous and generalized assessment of your child is completed. It is recommended to perform this examination between the 20th and 22nd week of gestation. This pregnancy time allows us to properly check the fetal development.

Morphological ultrasound is a thorough examination of the fetus, during which we will take several measurements, and assess all parts of the body (organs, limbs, spine, etc.). This important procedure is about ten minutes long only and is the same medical examination carried out in a hospital. If an anomaly is detected, our radiologist will immediately inform you.

Note that the position of your fetus, as well as the presence or absence of amniotic fluid in front of its face or the position of its hands, affect the quality of the images generated by ultrasound.
