Three-dimensional ultrasound is the latest technology applied to ultrasound.Ultrasound allows us to navigate through the three spatial planes obtaining volumes of anatomical structures.
When applied to obstetrics, tridimension (3D) visualisation of the fetus allows a close approximation to what might correspond to a photograph showing with great clarity and realism the face and all body parts. When activated the cuatridimensión (4D), i.e., the time, there is foetal movement in real time and even all their facial expressions can be seen.
This ultrasound examination system has many advantages over the conventional bidimensional scan:
In order for 3D or 4D to be successful a number of requirements are essential:
Three-dimensional ultrasound (3D) is a technique that goes beyond the diagnostic potential of ultrasound, especially in the field of Obstetrics. This situation has shown to be true in the following situations:
