BC数据与怀孕周数（BC data and number of weeks of pregnancy）

BC数据与怀孕周数（BC data and number of weeks of pregnancy） BC数据与怀孕周数(BC data and number of weeks of pregnancy) At the early fetal development process and ultrasound can see Pregnancy is a complex process, after fertilization of the egg, into the uterine cavity, the rapid growth until the mature embryo and appendages, have different changes every gestational age. What will your baby look like during the early stages of pregnancy? The following article will tell you more about it. Week 4: the fetus is only 0.2cm. When the fertilized egg just finished the bed, the amniotic cavity formed, and the volume was small. Ultrasound shows no signs of gestational age. 5 weeks: the fetus grows to 0.4 cm, enters the embryo period, the amniotic cavity expands, the original cardiovascular appears, can have the pulsation. B ultrasound can be seen in the pouch, which accounts for less than a quarter of the uterine cavity, or the fetal bud. 6 week: the foetus is 0.85cm, foetal head, brain vesicle, frontal organ, breathing, digestion, nerve and other organ differentiation, the B hyperfetal sac is clearly visible, and see the fetal bud and the placental leap. 7 weeks: the fetus grows to 1.33cm, the embryo has a prototype, the body segment is all differentiated, the limbs are divided, each system enters a step development. B is very clear to see the fetal bud and the fetal heart jump, the fetal sac about the l / 3 of the uterine cavity. Week 8: the foetus grows to 1.66 cm, the foetus is fixed, can be separated from the head, body and limbs, the fetal head is bigger than the torso. B hypervisible fetal sac is approximately 1/2 of the official cavity, fetal morphology and fetal movement are visible, and the yolk sac can be seen. 9 weeks: the fetus grows to 2.15cm, the fetal head is greater than the fetal body, the various parts are more clear, the head begins to calcify, the placenta begins to develop. B hypervisible sac is almost full of uterine cavity, fetal contour is clearer, the placenta begins to appear. 10 weeks: the fetus has grown to 2.83 cm, the fetal organs have been formed and the embryonic form has formed. B hypervisible sac begins to lose, the crescent placenta can be seen, the fetus is active in amniotic fluid. 11 weeks: the fetus grows to 3.62cm and the fetal organ develops further and the placenta develops. B hypervisible sac disappeared completely and the placenta was clearly visible. Week 12: the fetus grows to 4.58cm and the external genitalia is preliminarily developed. If there is a malformation, the head calcification is improved. The skull ring is clear, the double diameter can be measured, obvious deformity can be diagnosed, and then the organs tend to improve. The normal mid pregnancy ultrasound fetal development By ultrasound to judge the size of the fetal development during pregnancy is a way to have reference value, pregnant women look for when doing B to exceed to the inspection report there are some values, these values is to tell the size of your baby's development. To read these Numbers, you need to read the following articles carefully. 13 weeks of pregnancy: double top average diameter of 2.52 and 0.25 '6 of the mean value of 6.90 l. 65' femur length of 1.17 and 0.31. 14 weeks of pregnancy: double top diameter of the mean value of 2.83 and 0.57 '6 of the mean value of 7.77 7.77 femur length of 1.38 and 0.48.

How to see pregnancy ultrasound checklist during pregnancy, pregnant women will be 2-3 times of ultrasound, do you particularly want to know what report on all kinds of Numbers add up to? The ultrasonic examination report of the hospital generally includes the following aspects: fetal sac, fetal head, fetal heart, fetal movement, placenta, femoral bone, amniotic fluid and spine. What do they mean, what is normal, and what are the exceptions? Here are some reference indicators: 1. Fetal sac: the fetal sac is only seen early in pregnancy. Its size is about 2 cm in diameter at 1.5 months and about 5 cm in 2.5 months. The fetal sac position is normal in the uterus, anterior wall, posterior wall, upper and middle. Shape circle, elliptic shape, clear as normal; If the fetal sac is irregular shape, fuzzy, and position in the lower part, pregnant women also have abdominal pain or * * * bleed, can abort. 2. Fetal head: the contours are intact, the defect and deformation are abnormal, and no displacement or hydrocephalus is normal in the brain. BPD has a double head diameter, which should be 9.3 centimeters or more when the baby is pregnant. According to the general law, after 5 months of pregnancy, basic consistent with pregnant a month, that is to say, the 28th week of gestation (7 months) when the BPD is about 7.0 cm long, at 32 weeks (eight months) of about 8.0 when m, and so on. After eight months of pregnancy, the average weekly increase of about 0.2cm is normal. 3. Fetal heart: yes, strong is normal, no, weak is abnormal. The normal fetal heart rate is between 120 and 160 times per minute. 4. Fetal movement: there is a normal, no, weak possibility that the fetus is sleeping, and may also be abnormal, combining with other items. 5. Placenta: the position of the placenta in the uterine wall; The normal thickness of the placenta should be between 2.5 and 5 cm; Calcified ? grades on a report card, ? level placental maturity in the early stages of the echo uniform, in the 30-32 weeks pregnant visible to such change; Grade ? said placenta close to maturity; ? level suggests the placenta is ripe. The closer to full term, the more mature the placenta, the uneven echo. 6. Length of femur: the length of the thigh bone of the fetus, the normal value of the femur is 2 to 3 cm from the value of the corresponding pregnant month. For example, the BPD is 9.3 cm, and the length of the femur should be 7.3 cm. The BPD is 8.9 cm and the length of femur is 6.9 cm. 7. Amniotic fluid: the depth of the amniotic fluid is normal between 3 and 7 cm, more than 7 centimeters for amniotic fluid and less than 3 cm for amniotic fluid. 8. Spine: fetal spine is normal, defect is abnormal, may have abnormal spine. Umbilical cord: normally, the umbilical cord should float in the amniotic fluid. If the umbilical cord is seen in the fetal neck, it may be around the neck of the umbilical cord. 1. CS is fetal sac. Menstruation rule of women, suspended for 35 days, B super can see the pregnancy capsule in the uterine cavity. 1 in her pregnancy. The pregnancy capsule is about 2 cm in diameter at 5 months and about 5 cm in 2.5 months. The fetal sac position is normal in the uterus, anterior wall, posterior wall, upper and middle. Shape round, oval, clear and normal; If the fetal sac is irregular shape, blurred, and the position is in the lower part, the pregnant woman may have a miscarriage when she has abdominal pain or vaginal bleeding. 2. The CRL is the head and buttock distance, indicating the maximum length axis of the longitudinal axis of the fetal body, which is mainly used to determine the gestational age of 7 ~ 12 weeks. 3. BPD is the double diameter of fetal head. 4. FL is the fetal femur. 5. GP is the placental grading, the common placenta is divided into 0, I, II, III, and sometimes III +. 6. The AI for the amniotic fluid index, make B timeout, centered on pregnant women the bellybutton, up, down, left, right four areas, the four areas of the depth of the amniotic fluid additive, get the amniotic fluid index, the normal late pregnancy amniotic fluid index is 8 ~ 18 li meters. 7. For fetal umbilical artery S/D ratio of systolic and diastolic blood pressure, is associated with fetal blood, when the placenta dysfunction or abnormal umbilical cord will be abnormal, the ratio in normal pregnancy cases, with the increase of gestational fetus under the need to increase the S, D, make the ratio drops, nearly full-term pregnancy when the S/D less than 3. 8.
