4D Ultrasound & Detailed Anomaly Scan in Ankara

Detailed ultrasonography is an imaging method ideally performed between the 18th and 24th weeks of pregnancy. In this examination, fetal anatomy and development are evaluated comprehensively, and every region of the fetus is examined individually and in detail for abnormalities.

In addition, the adequacy of the amniotic fluid, the presence of bleeding or any abnormality in the placenta, as well as the structure of the umbilical cord connecting the fetus and placenta, and blood flow patterns are evaluated with Color Doppler examination.

When is 4D Ultrasound Performed?

The ideal time for a detailed anomaly scan is between the 18th and 24th weeks of pregnancy. However, in high-risk pregnancies or cases of abnormal screening tests, early anomaly screening can be performed around the 15th week and onwards. However, when early anomaly screening is performed, the evaluation of some fetal structures may not be sufficient, in which case re-evaluation may be required later.

What is 4D Ultrasound?

4D Ultrasound is an advanced technology that provides a simultaneous dynamic and moving spatial view of the baby on the screen (Real-time 3D).

In our clinic in Ankara, we use the high-end Mindray DC-8 ultrasonography device, which features 4D capability. In addition to the detailed medical scan, we provide our patients with live 4D video recordings and 4D photos of the baby at the end of the examination.

Why is Detailed (4D) Ultrasound Done?

Today, detailed ultrasonography is an indispensable and fundamental imaging method to detect high-risk pregnancies among those that are unpredictable or predicted by various tests. The risk of major congenital anomaly for the general population is between 2-3%.

Detecting an anomaly during detailed ultrasonography allows for early knowledge about the problems awaiting the baby prenatally or postnatally. Thus, options for managing the process during pregnancy and after birth are increased.

What is Examined in a Detailed Scan?

In detailed ultrasonography, the baby’s head, brain, fluid spaces in the brain, cerebellum, facial structures, neck region, spine, chest cavity, heart, abdominal region, genital area, arms, hands, legs, and feet are examined in detail in different planes. Also, the gestational sac, placenta, and umbilical cord are carefully evaluated for any abnormalities.

Can All Diseases Be Diagnosed with Detailed Ultrasound?

Although abnormalities in the fetus can be detected at a very high rate in detailed ultrasound examination, it is not possible to diagnose every disease. The most important reasons for this are that some congenital defects do not give findings on ultrasonography (e.g., some metabolic diseases or autism) and some congenital defects appear only in the late stages of pregnancy.

How Long Does the Scan Take?

With an advanced ultrasonography device and an experienced doctor, the examination takes approximately 30 minutes. The examination has no harmful effect on the baby.

However, sometimes the baby’s position may not be suitable for examining some fetal structures or obtaining a 4D face image. In this case, your doctor may ask you to walk for a while or eat something sweet and take you to the examination again, which may extend the procedure time slightly.

Can 4D Ultrasound Be Done Every Week?

4D USG is performed as a complementary test to detailed ultrasonography at 18–24 weeks. On the other hand, especially after the 26th week, since the baby’s facial features will be more distinct (chubby cheeks), much clearer “baby face” images can be obtained if there is sufficient amniotic fluid and suitable fetal position. This is often preferred for bonding purposes.
