Just kidding, hey ~ ~

First: Look at the data. If the length and width are more than doubled, the baby is more likely to be a boy. Baby girls are more likely to be equal in length and width. Second: Look at the shape. Eggplants or long strips are more likely to be male babies, and round ones are more likely to be female babies. We all know that unless there are special reasons, hospitals are forbidden to use B-ultrasound to detect the sex of the fetus, including pregnant women who refuse to answer questions. The pregnant woman is going to have a B-ultrasound now. The doctor knows that she will have a boy and a girl, but what should she do if she doesn't tell you? Don't worry, she has to give us a B-ultrasound! Secretly tell you: another beauty of the B-ultrasound list is to let the B-ultrasound list tell you the baby's sex: first, look at the data. If the length and width are more than doubled, the baby is more likely to be a boy. Baby girls are more likely to be equal in length and width. Second: Look at the shape. Eggplants or long strips are more likely to be male babies, and round ones are more likely to be female babies.

Gestational sac: 25mm 1 1mm boy 5. Data: embryo sac: 23× 17× 16 gave birth to a little beauty. 6. Data of 46 days BC: gestational sac: 20 17 17. Girls 7, 7W+65438. At 8 weeks, it was 1.6× 1.7, which was a golden daughter. At 9 and 8 weeks, it is 4 128MM, and it is also BC for female babies over 10 and 8 weeks. Gestational sac19 mm10 mm. Later, BC showed that it was also a baby boy 1 1, and the gestational sac was 35 mmx 34 mmx 28 mm. Lovely girl 12, gestational sac size (length) 18MM X (width)16 mm. 62 days: I saw the gestational sac 2.6 1.8 and gave birth to a lovely baby boy 14 for 50 days. The gestational sac was 35 mm and 27 mm and gave birth to a baby girl 15, and the gestational sac was 33 18. At present, the B-ultrasound is a boy 16, the gestational sac length is 4420mm, and the boy was born 17, 9 weeks +6 days BC, and the result is 5.62.4 weeks +5 days BC, showing that it is a boy 18. After more than 7 weeks of B-ultrasound data, the gestational sac gave birth to a baby boy of 3.82.3CM, 19 cm and a cute baby boy of 3.32.0cm. The second magical function of B-ultrasound is to know the fetal development. The second magical function of B-ultrasound is to know the fetal development. GS- gestational sac is also called gestational sac. Women who have regular menstrual cramps for 28-30 days will stop menstruating in 35 days. B-ultrasound can show that there is a fetal sac in the uterine cavity. The gestational sac is about 2 cm in diameter at the sixth week of pregnancy and 5 cm in diameter at the 10 week of pregnancy. The position of fetal sac is normal in the bottom, front wall, back wall, upper part and middle part of uterus. Normal shape is round, oval and clear; If the fetal sac is irregular, fuzzy and located below, pregnant women may have an abortion with abdominal pain or vaginal bleeding at the same time. Embryo bud: early fetus. Germ CRL- head-buttock length is the distance between the head and buttock of the fetus, indicating that the longitudinal axis of the fetus is parallel to the longest axis, which is mainly used to determine the gestational age of 7 ~ 12 weeks. Estimated gestational age (week) 6- 13 weeks = head and hip length FH- fetal head: complete contour is normal, defect and deformation are abnormal, midline of brain is normal, and there is no displacement and hydrocephalus. BDP-the length of the widest part between the left and right sides of the fetal head, also known as "large transverse diameter of the head". It should reach more than 9.3 cm at full term. According to the general rule, after 5 months of pregnancy, it basically coincides with the month of pregnancy, that is, the BPD of 28 weeks (7 months) is about 7.0 cm, and that of 32 weeks (8 months) is about 8.0 cm, and so on. After 8 months of pregnancy, it is normal to grow about 0.2 cm per week on average. When the expected delivery date cannot be determined by CRL in the early stage, BPD is often used for forecasting; After the middle period, it is often necessary to measure these data when estimating fetal weight. H— Fetal heart: 7-8 weeks pregnant, and fetal heart beat can be seen by B-ultrasound at the 6th weekend of the first pregnancy. The normal frequency of fetal heart beat is between 120- 160 beats per minute. FL- Femoral length: It is the length of fetal femur, also known as "femur length, femur length". Refers to the length of femur from the root of fetal thigh to knee. The difference between the normal value and the BPD value of the corresponding pregnancy month is about 2-3 cm. For example, the BPD is 9.3 cm and the femur length should be 7.3 cm. BPD 8 years old. 9 cm, femur length should be 6.9 cm, etc. Usually, at about 20 weeks of pregnancy, the development of the fetus is checked by measuring FL. SP- spinous process: fetal spinous process can be seen after 0/2 weeks of pregnancy, but it can be clearly distinguished at 20 weeks of pregnancy. The fetal spine is continuous and normal, the defect is abnormal, and the spine may be deformed. FM- fetal movement: fetal movement can be seen by B-ultrasound at 8-9 weeks of pregnancy. Strong is normal, weak may lead to fetal sleep or abnormality, which should be comprehensively analyzed in combination with other items. Umbilical cord-Under normal circumstances, umbilical cord should float in amniotic fluid. If you see the image of the umbilical cord in the fetal neck, it may be that the umbilical cord is around the neck. "V" stands for umbilical cord around the neck. PL- placenta: position indicates the position of placenta on the uterine wall; The thickness of normal full-term placenta should be between 2.5 and 5 cm. GP (Placenta Classification) Generally, placentas are classified into grades 0, I, II and III. Grade ⅰ is the early stage of placental maturity, with uniform echo, which can be seen at 30-32 weeks of pregnancy; Grade ⅱ indicates that the placenta is close to maturity; Grade ⅲ indicates that the placenta is mature, and there are many calcifications in the placenta, which are small grains of sand, which generally do not pose a threat to fetal life, but should be paid attention to. The closer to term, the more mature the placenta, and the uneven echo. AMN—- amniotic fluid: MVP (maximum vertical amniotic fluid depth in sheep pond) is normal when it is between 3-7 cm; If it exceeds 7 cm, it means that amniotic fluid is increasing; If it is less than 3 cm, it means that amniotic fluid is reduced. AFI (amniotic fluid index) is centered on the navel of pregnant women and divided into four areas: upper, lower, left and right. Amniotic fluid index is obtained by adding the depth of amniotic fluid in four areas. The normal amniotic fluid index in the third trimester is 8 ~ 18 cm. More than 18 cm is amniotic fluid increase, and less than 8 cm is amniotic fluid decrease. AFI is more scientific in judging amniotic fluid volume. S/D (A/D) —— The ratio of umbilical artery systolic pressure to diastolic pressure is related to fetal blood supply. When the placenta is dysfunctional or the umbilical cord is abnormal, this ratio will be abnormal. In normal pregnancy, with the increase of gestational age, the fetus needs to increase S to decrease, and increase D, so the proportion will decrease. In the third trimester, S/D is less than 3. The common abbreviations of fetal B-ultrasound are TCD: transverse diameter of cerebellum HC: head circumference AC: abdominal circumference FTH: the signature document of fetal leg subcutaneous fat thickness.
