Ultrasound examination for detecting fetal anomalies


Ultrasound examination performed at 20 weeks of pregnancy offers the possibility to examine the fetus and placenta, determine his/her sizes and lie, measure amniotic fluid level. At the beginning of the examination head, abdomen and extremities of fetus are measured. Measurements taken are entered to a special table and estimated fetal weight is calculated. During the same examination fetal heart rate is recorded, brain structures, vertebral column, intestines, and other internal organs are examined to exclude birth defects. This examination does not provide a guarantee that fetus will be absolutely healthy. We also make examination of placenta and measure amniotic fluid index. During the examination determination of gender is possible at your request.

How is the examination performed?

• Examination is performed by transabdominal approach at 18-22 weeks of gestational age.
• More detailed examination of fetal heart and brain structures is possible at this stage of pregnancy.

Which structures of fetus are examined during the examination?

Fetal heart, brain, structures of face, vertebral column, intestines, stomach, kidneys, extremities, fingers.

What information is obtained through this examination?

• Location and various abnormalities of placenta.

• Cervical length.
• Determination of gender (at your request).
Indication for examination

How to prepare for the examination?

Urinary bladder should be filled in order to receive better images during transabdominal examination.

Which is the following examination?

The following examination is performed at 31-34 weeks of gestational age.

Determination of cervical length by ultrasound is indicated in pregnant women who are at risk of preterm delivery. This screening examination is performed at 17-24 weeks of gestational age. 

How is this examination performed?
Screening-examination for determination of cervical length is performed by transvaginal approach.

What results are expected to receive from this examination?

At 16-20 weeks the cervical length should not measure less than 25mm. If the examination shows that cervical length is less than 25 mm, consultations with your physician is required. Repeat measurement of cervical length may be performed again in several weeks.

Indication for conduction of this examination

• History of preterm deliveries.
• History of preterm rupture of amniotic membranes. 
• History of surgeries and various procedures performed on uterine cervix.
