How much is Anyang pregnant to do color Doppler ultrasound?
What should three-dimensional color Doppler ultrasound check? According to experts, there are mainly the following aspects:
Uterus: Three diameter lines need to be measured, namely, the longitudinal diameter, the transverse diameter and the anteroposterior diameter of the uterine body.
1, measurement of uterine longitudinal diameter (upper and lower diameter):
(1) Measurement section: sagittal section of uterus. It is necessary to clearly show the symmetrical section from the bottom of the uterus to the cervix, myometrium and endometrium.
(2) Measurement position: uterine body: the distance from the outer edge of the uterine bottom to the internal cervix. Cervical cavity: the distance from the inner cervical cavity to the outer cervical cavity.
(3) Normal value: uterus 5.0 cm, 1.0cm, cervix 2.5-3.0cm.
2. Measurement of transverse diameter (left and right diameter) of uterine body:
(1) Measurement section: coronal section of uterus. It is necessary to transect the uterus and measure it in the middle of the uterus when the image is an ellipse with the largest cross section (not in the triangular image).
(2) Measurement position: the maximum left and right diameter through the uterine body.
(3) Normal value: 4.3 soil 0.73cm
3. Measure the anteroposterior diameter of the uterus (that is, measure the distance between the two outer edges of the endometrium):
(1) Measurement section: the same as the longitudinal diameter measurement plane of uterus.
(2) Measurement position: perpendicular to the longitudinal uterine meridian, measure the maximum anteroposterior distance.
(3) Normal value: 4.3 cm.
Ovary: We also need to measure three diameter lines, longitudinal diameter, transverse diameter and anteroposterior diameter.
0 1. Measurement section: The measurement of longitudinal diameter, transverse diameter and anteroposterior diameter is the same as that of uterine measurement section. When the ovary is difficult to identify, the patient can be placed in an oblique position, and the contralateral ovary can be scanned and measured through the filled bladder through the acoustic window.
02. Measurement position: the maximum diameter line passing through the ovary.
03. Normal value: Because the size of ovary is related to age and other factors, the commonly used volume formula is: length× width× thickness /2, which should be less than 6ml under normal circumstances. The size of an adult female ovary is about 4cm×3cm× 1cm. ...
Three-dimensional color Doppler ultrasound mainly uses the most intuitive method to see whether the baby's appearance and internal organs development are complete and healthy. The effect is similar to those of fetal pictures in science and education films or color science and education books, with high definition and clear organ development.
Three-dimensional color Doppler ultrasound can realize three-dimensional imaging of human local tissues and organs, and can be used for volume scanning of abdomen and small organs to accurately measure local tissues and organs. For example, during 9- 13 weeks of pregnancy, hereditary (chromosomal) malformation can be found by examining the skin on the back of the fetal neck and measuring the thickness of subcutaneous tissue. The outstanding feature of three-dimensional color Doppler ultrasound is that it can capture local three-dimensional images of fetal growth and development in different gestational weeks. From the three-dimensional image, we can clearly see the left ear, fist and vivid facial expression of the sleeping fetus in the uterus. These are all beyond the reach of ordinary B-ultrasound.
When is the best time to do three-dimensional color Doppler ultrasound?
Women can do three-dimensional color Doppler ultrasound at specific stages of pregnancy. This kind of color ultrasound can observe the baby's condition very clearly, and can also find out whether there are some deformities. There are more and more deformed babies now. So, when will the three-dimensional color Doppler ultrasound be done?
Generally speaking, the first color Doppler ultrasound is done from 22 weeks to 24 weeks, which is usually used to see if the baby is deformed, especially the cleft lip of the upper lip, which is often called rabbit lip. You can find out at this time. And the continuity of the spine, internal organs and so on. The most important thing is to look at the baby's development, baby's biparietal diameter, head circumference, abdominal circumference, femur length and so on.
The second color Doppler ultrasound is mostly done at 28 ~ 30 weeks, and it is also used to screen out abnormalities. At this time, the baby has grown up a lot, and can see the parts that can't be seen for the first time more clearly, and can further understand the development of placenta, amniotic fluid and baby. At this time, you can get a general idea of the size of the baby and the maturity of the placenta.
About 37 weeks, you need to do another prenatal color Doppler ultrasound to see the placenta and amniotic fluid and predict the baby's weight. Is the umbilical cord around the neck? Wait, let's see if mom is suitable for a natural birth.
If everything is normal during pregnancy, you can do 1~2 B-ultrasound examinations throughout pregnancy. So, when is the appropriate time to do the first B-ultrasound? This is also a concern of many pregnant women. For the sake of the health of the fetus, if there are no special circumstances, it is best to have the first ultrasound examination at 18~20 weeks of pregnancy. During this period, all the organs of the fetus have been fully developed, and careful B-ultrasound examination can show whether every important organ is abnormal. Fetal malformation can be found early, pregnancy can be terminated in time, and the impact on the mother's body is also small. If there are no abnormalities in the future, you can wait until the last few weeks of pregnancy to do the second B-ultrasound examination, estimate the size of the fetus, and understand the position of the placenta and the amount of amniotic fluid. ...
Many pregnant mothers will want to know the baby's development after pregnancy. Now, this requirement of pregnant mothers is not high at all. The three-dimensional color Doppler ultrasound examination introduced by the hospital can satisfy this wish of pregnant mothers. So, what is the three-dimensional color ultrasound examination?
At the beginning of pregnancy, if the pregnant mother wants to know the baby's development, she can go to the hospital for a three-dimensional color ultrasound examination, so that she can know the baby's dynamics for the first time. When going to the hospital for examination, experts reminded pregnant mothers to go to regular hospitals for examination.
According to experts, three-dimensional color Doppler ultrasound shows a real-time continuous observation process on the basis of ordinary color Doppler ultrasound, and the whole process is like showing a movie. Three-dimensional color Doppler ultrasound examination can also observe the development of intrauterine fetus from multiple directions and angles, thus providing accurate scientific basis for the early diagnosis of fetal congenital malformation and other diseases, and pregnant mothers can rest assured to do a good job during pregnancy.
Three-dimensional color Doppler ultrasound is an excellent ergonomically designed ultrasonic diagnostic instrument, which has no radiation such as rays, light waves and electromagnetic waves, and has no impact on human health. If a pregnant mother wants to leave a good memory for her baby, she can go to the hospital for a three-dimensional color ultrasound examination.
Three-dimensional color Doppler ultrasound can measure fetal age, evaluate multiple or high-risk pregnancies, analyze fetal development, detect abnormal pregnancies such as placental abnormality and ectopic pregnancy, detect abnormal uterine structure, locate placenta, detect abnormal fetal bleeding, detect ovarian tumors and fibromas, and automatically take "photos" and dynamic videos for the fetus, or real-time moving images of human internal organs. ...
