Answers to frequently asked questions about our 3D, 4D, 6D Plus ultrasound and booking in Paris.
From when can you find out your baby's sex?
From 14 weeks after conception (16 gestational weeks) at Echografilm, to qualify for the commercial sex-determination guarantee.
What is the difference between 3D and 4D?
3D ultrasound shows a three-dimensional image. 4D adds movement: depending on the package, a keepsake video can be sent to you.
What is 6D Plus?
It is a 3D image processed with artificial intelligence as a keepsake, not a medical ultrasound or a photograph predicting the baby's face at birth.
Are 3D photos and 6D renderings guaranteed?
No. They depend on the baby's position, pregnancy stage and visibility of the face. 6D Plus is offered when the original 3D image permits it.
When should I book a 3D/4D or 6D session?
The suitable period depends on the package. For facial images and 6D Plus, around 25 to 30 weeks after conception is often favourable. Check our pregnancy calendar.
Can I see example photos and videos?
Yes, the Echografilm gallery shows 3D photos, 4D videos and 3D → 6D Plus comparisons.
Can I arrange a surprise or gender reveal?
Yes. You can ask not to discover your baby's sex immediately and arrange the announcement to loved ones according to the available options.
How can I change or cancel my appointment?
Log in to My account within the minimum notice period specified when booking. If your appointment is too soon, contact Echografilm. The account email can only be changed by Echografilm.
Which package should I choose?
The Girl or Boy option focuses on sex determination. Admiration packages offer a longer keepsake session with photos and video; 6D Plus depends on imaging conditions. Always check current features and prices before booking.
Can I have a 3D ultrasound instead of a medical ultrasound?
No. Echografilm offers only a non-medical experience: it does not replace any diagnosis, screening or pregnancy care.
Where is Echografilm in Paris?
At 78 avenue des Champs-Élysées, 75008 Paris, staircase A, 1st floor, door 132.
Les exemples de la galerie correspondent-ils à mon résultat ?
Chaque bébé et chaque séance sont différents. La visibilité du visage dépend notamment de la position et des conditions d’acquisition. Les images de la galerie illustrent nos réalisations ; elles ne garantissent ni une pose identique ni un rendu identique pour votre séance.
14 weeks : weeks after conception ou d’aménorrhée ?
La détermination de sexe du bébé chez Echografilm est proposée à partir de 14 weeks after conception, soit 16 gestational weeks. Consultez les conditions actualisées du forfait Girl or Boy et le calendrier calculé selon votre DPA avant de choisir un créneau.
