Three-dimensional ultrasonography at pregnancy. In what its pluses and minuses?
in obstetric practice more and more are widely adopted in recent years three-dimensional ultrasonography of a fruit. Let`s try to understand advantages of a technique and its possible shortcomings.
Standard ultrasonic research allows to receive the two-dimensional picture - the image of a cut of fabrics of a fruit in the field of influence of ultrasound. It is enough for definition of a condition of a fruit and possible anomalies of development. Additional use of doppler sonography allows to estimate quality of blood circulation between mother and a fruit.
What diagnostic opportunities of three-dimensional ultrasonic research?have not enough
In some situations of usual two-dimensional research. The nezarashcheniye of a spinal cord, congenital anomalies of skin are, first of all, about visualization of defects of the person, exact definition of quantity of fingers on hands and legs, detection of anomalies of genitals. In this case three-dimensional ultrasonic research comes to the rescue.
It helps and with exact sex determination of the child. The volume image allows to see a fruit entirely and in parts, the child`s face is well visualized. These opportunities of a technique also attract parents. To receive a photo album of the kid till his birth, and when using ultrasonography 4D at pregnancy - the present video movie, many wish.
So in what distinction between 2D and 3D researches?Two-dimensional procedure issues to
on the screen the flat picture which to understand among a congestion of points and hyphens only the ultrasonographer can. At three-dimensional research the image becomes volume and color, though static, at four-dimensional - the object moves in real time, allowing to do video. Such effect is gained when using the special sensor scanning a fruit mayatnikoobrazno. The received cuts of fabrics are exposed to computer processing therefore the image becomes volume.
Pluses and minuses of 3D research
Important plus of three-dimensional research (except above-mentioned diagnostic opportunities and powerful emotional influence) is preservation of the same parameters of an ultrasonic wave (frequency of scanning, power and intensity of influence), as at two-dimensional inspection.
If to speak about minuses, then for three-dimensional procedure it is influence duration: usual ultrasonography lasts about 15 minutes whereas 3D - 45 - 50 minutes.
Besides, three-dimensional research has a number of the restrictions connected with the term of pregnancy and that situation which occupies a fruit during procedure.
So, optimum term for performance of 3D research - 24 weeks of pregnancy not earlier. Exactly by this time all superficial structures of a fruit are created and it is possible to distinguish various external anomalies more precisely.
Difficulties often arise if when carrying out ultrasonic research the kid turns a back to the sensor. Instead of the person it is necessary to behold only the child`s back.
Two-dimensional ultrasonography allows to carry out full diagnostics of all internals in any situation and it is correct to interpret the obtained information.
Safety of 3D ultrasonography of a fruitthe Ultrasonic research applied in obstetrics is safe
for mother and a fruit. Long-term clinical experience of use of a technique proved it. Three-dimensional inspection - not an exception.
By the way, duration of impact of ultrasound on an organism of mother and the child does not exceed one percent from the general time of procedure. The rest of the time occurs reception and processing of the arriving information. However any impact on a fruit has to be reasonable and continue exactly so much how many it is necessary.
3D ultrasonography of a fruit is a high quality of diagnostics and full safety of inspection.
