3D/4D Ultrasound

Advanced ultrasound imaging of anatomy in real time (4D) and 3D reconstruction.

3D ultrasound provides a three-dimensional static view, while 4D ultrasound shows movement “live” and adds an extra level of visualization in pregnancy and in gynecological diagnostics. At Polyclinic Cito we use the Voluson Expert Series 22 - the most advanced ultrasound system for gynecology and perinatology, delivering top-quality imaging and a more precise assessment. The exam is performed by a specialist gynecologist with a clear explanation of the procedure, what we are looking at and what the specific image means. 

Page Overview

What is the difference between 3D and 4D ultrasound?

3D ultrasound gives a static view of the anatomical structure in a three-dimensional (volumetric) display, while 4D ultrasound shows the 3D image moving in real time. In gynaecology they are used for a more precise insight into the anatomy (e.g. the uterus, endometrium, ovaries), and in pregnancy for a realistic and clear view of the foetus, and for additional assessment where it is useful.

During pregnancy these examinations are very important and allow a more detailed insight into the development of the foetus. This technology provides a clear view of the facial structure and can help in spotting certain anomalies. It also allows the spine to be examined from different angles and a volumetric view of the brain, which gives doctors additional information about the development of important structures.

Beyond its medical significance, for many parents this examination also brings a special moment, the chance to clearly see their child for the first time before birth. 

Note: The use of 3D and 4D ultrasound in pregnancy or gynaecology has been shown not to be harmful to the foetus or to the patient's fertility. 

What a 3D/4D ultrasound includes

  • An expert examination with a 3D and 4D ultrasound device
  • Reconstruction of the uterus or foetus in 3D
  • Volumetric views and measurements (if needed)
  • Advanced 3D and 4D techniques for better visualisation of complex pathology
  • A real-time view of anatomical structures in order to reach a more accurate diagnosis

When is a 3D/4D ultrasound recommended in gynaecology and when in pregnancy?

3D and 4D are particularly useful when we want to examine the shape and relationships of structures in more detail, or to confirm a finding that is not completely clear on a basic gynaecological ultrasound (2D).

The most common indications in gynaecology

  • Suspicion of anomalies in the structure of the uterus (e.g. a septum, a bicornuate uterus)
  • Assessment of the uterine cavity and endometrium (if needed)
  • Polyps, fibroids - a better assessment of their position and relationship to the uterine cavity
  • Assessment of the ovaries and cysts in more complex cases

The most common indications in pregnancy 

  • A more detailed assessment of the anatomy of the foetus's face (e.g. suspicion of a cleft lip or palate)

  • A more precise view of the development of the spine and possible anomalies

  • A volumetric view of the brain and the structures of the central nervous system

  • Additional diagnostics when there is a suspicion of developmental anomalies on a standard ultrasound

Note: A 3D/4D ultrasound is not a standard part of the examination; depending on the assessment of our team of doctors, it may be suggested whether this technique is needed.

What does a 3D and 4D ultrasound look like?

The examination is performed by an expert gynaecologist, experienced in working with the wide range of functions this technology offers. 

1. Conversation and medical history

During the conversation, which is often preceded by a basic gynaecological examination, if a 3D/4D ultrasound examination is needed your gynaecologist will take the basic details and give guidance for the next steps. 

2. 3D/4D ultrasound examination

It is performed like a standard gynaecological examination. Gel is applied to the abdomen, and the gynaecologist moves the ultrasound probe over the abdomen to obtain a three-dimensional image or a real-time view of movement. 

3. Interpreting the findings

You receive the findings immediately after the examination. Depending on the diagnosis, your gynaecologist explains the images in detail or, if needed, gives a plan for the next steps. 

4. Digital copies

In addition to the basic image, all the necessary images taken during the examination can also be sent in digital form. 

Depending on the diagnosis, the examination most often lasts between 10 and 40 minutes.
Cito Polyclinic uses the most advanced 3D/4D ultrasound devices, which meet the strictest safety standards.

How to prepare for the examination?

Preparation is simple, and a few details can help the quality of the examination.

  • Bring earlier documentation and findings (if you have them).
  • In gynaecology: come when it suits you, unless a particular part of the cycle has been recommended.
  • In pregnancy: there is no need to fast, come relaxed and in comfortable clothing.

Frequently asked questions before a 3D and 4D ultrasound examination

  • Do I need to come with a full bladder?
    As a rule no (unless we specifically tell you).
  • Can I get a “perfect” 3D image every time?
    Not always. In pregnancy it depends most on the baby's position and the imaging conditions.
  • Is this ultrasound a replacement for standard examinations?
    No, standard protocols remain the basis of monitoring.
Note:When booking, it is advisable to mention that you are interested in having a 3D/4D ultrasound, so that the appointment can be organised accordingly.

What do you gain from this examination?

More clarity and better visualisation - with expert interpretation and a plan.

1
More advanced visualisation
3D spatial display and 4D movement “live”
2
An expert assessment
A standard examination with an additional view and an expert explanation of the findings 
3
A follow-up plan
When it makes sense to repeat the examination or monitor the findings

In practice this means

  • a more detailed view of the uterus, endometrium and cavity (in gynaecology)
  • a more precise assessment of the relationship of fibroids/polyps to the uterine cavity (if needed)
  • a more realistic view of the foetus in pregnancy (3D) and a view of movement (4D)
  • expert interpretation of the findings and clear recommendations

Why choose Cito Polyclinic?

We combine top technology and an individual approach - discreetly, professionally and in a pleasant atmosphere. 

  • Examinations on the Voluson Expert Series 22 (top image quality)
  • Enough time for the examination and questions
  • Expert interpretation of the findings (not just “showing the image”)
  • A discreet and calm approach, without rushing

Want the best moment for a 3D and 4D ultrasound?

For the best result of a 3D/4D display in gynaecology, timing is important! Tell us your symptoms or concerns, and we will advise you on an appointment that ensures maximum visibility of detail.

For the best image in pregnancy, it is recommended to have the examination between the 24th and 32nd week, when the baby is already sufficiently developed but there is still enough room and amniotic fluid to show the face and movements. 

Price of a 3D and 4D ultrasound examination

The price of the examination at Cito Polyclinic is 80€. Any additional tests, if needed, are charged separately, as required.

You can get the first available appointment straight away by phone on +385 21 457 800 or by sending a short message via the contact form.

Frequently Asked Questions

Find answers to common questions about this service

At what gestational age is 3D/4D ultrasound recommended?

3D/4D ultrasound can be performed at any stage of pregnancy, but the best visualization of the face and limbs is between the 22nd and 26th week of pregnancy.

What is the difference between 2D, 3D and 4D ultrasound?

2D shows cross-sections in real time for diagnosing anatomy. 3D provides organ reconstruction with better visualization and more precise diagnostics, while 4D allows display of the 3D volume in motion.

Is the exam safe and how long does it last?

Ultrasound uses mechanical waves, with no ionizing radiation, and is considered safe within standard parameters. The duration depends on the indication and may last 5-20 minutes.

May I eat/drink before the exam and do I need a full bladder?

Eating and drinking normally before the exam is fine. Before a transvaginal ultrasound it is advised to empty the bladder. The exception is a transabdominal ultrasound, where a full bladder is needed for easier visualization of the pelvic organs.
