1. What is early three-dimensional ultrasound
1. Three-dimensional B-ultrasound is a type of color ultrasound. Three-dimensional color ultrasound is a three-dimensional dynamic display
2. Early three-dimensional, as the name suggests, it can show the three-dimensional picture of the pregnant woman\’s uterus. The three-dimensional b-ultrasound can see the fetus clearly and clearly. It can not only see the appearance of the fetus. , you can also see the baby sucking his fingers, covering his face with his hands, opening his eyes, sticking out his tongue, drinking amniotic fluid, dancing and other various movements and expressions.
2. How to perform gynecological three-dimensional color ultrasound on an empty stomach?
Gynecological three-dimensional color ultrasound examination generally does not require fasting, but if it is not during pregnancy, then It is also necessary to hold urine for examination. Such examination results are more accurate. If there is anuria or relatively small urine, it will not be able to play the role of the examination, so it is best to hold urine in advance. This is more conducive to inspection.
3. Is there a big difference between three-dimensional and actual conditions
1. Three-dimensional color ultrasound is generally similar to the actual appearance, but there may be certain differences
2. During pregnancy, you can go to the hospital for three-dimensional color ultrasound Examination, through three-dimensional color ultrasound examination, the specific growth and development of the fetus can be observed. UsuallyThe results checked below are relatively similar.
Four. What is three-dimensional
Three-dimensional refers to the two-dimensional A space system composed of direction vectors is added to the maintenance system. Three dimensions are the three axes of the coordinate axis, namely the x-axis, y-axis, and z-axis, where x represents the left and right space, y represents the front and rear space, and z represents the upper and lower space (the plane rectangular coordinate system cannot be used to understand the spatial direction). In terms of practical applications, the X-axis is generally used to describe left and right movement, the Z-axis is used to describe up-and-down movement, and the Y-axis is used to describe forward and backward movement, thus forming a human visual three-dimensional sense.
5. How to see the results of three-dimensional color ultrasound
The main features of three-dimensional color ultrasound The following data indicators, taking fetal three-dimensional color ultrasound as an example: check whether the fetal skull outline is complete, and whether the midline of the brain is not shifted or hydrocephalus; look at the size of the fetal biparietal diameter, the biparietal diameter range of a full-term fetus is 8-10 cm, and the color ultrasound instrument can Fetal weight is estimated from data such as biparietal diameter.
Check whether the fetal heart rate is normal, the normal fetal heart rate is 120 to 160 times per minute; look at the position and thickness of the placenta, the normal term placenta position cannot be anterior. , the thickness is 2.5-5 cm;
Look at whether the umbilical cord is around the neck; look at the amount of amniotic fluid, the normal range of amniotic fluid depth is 3-7 centimeters; look at the length of the femur, it is normal The difference between the value and the biparietal diameter value of the corresponding pregnancy month should be less than 2-3cm.
6. What does three-dimensional color ultrasound mean
Ultrasound has one dimension and two dimensions Three-dimensional and even now four-dimensional, the images are getting clearer and clearer. Three-dimensional color ultrasound shows a three-dimensional structure, so it can be seen more clearly. It will play a certain screening role in the fetus, such as finding malformations or abnormalities in certain parts of the body. As the dimensionality gets higher and higher, the clarity will get higher and higher.
The article ends here. If the question of what three-dimensional ultrasound and three-dimensional color ultrasound shared this time solves your problem, then we are sincerely happy!
