What is the B ultrasound test?

The main reason is that the time of your examination is too early, so you can only see the gestational sac, and you can't see the germ and fetal heartbeat, which is very normal, the baby has not developed to a certain time, of course, you can't see it, it is recommended to go to the re-examination after half a month, you can almost see it, the baby should be no problem, rest assured, as long as there is no bleeding and severe abdominal pain during this period, it means that the problem is not big, and you can wait for the re-examination with peace of mind.

Let me be verbose, the current doctors are really lacking in morality, they know that they can't see clearly so early, and they always let others take pictures, which is obviously to earn your super money for nothing. Angry ......Many expectant mothers are worried and speechless all day long.

Why did the doctor determine that the fetus was dead so quickly, I have seen some pregnant women like you, and they were checked early, the doctor said that they were stillborn, and asked for an abortion, and then the woman did not do it, so she insisted on waiting for a while, and after a while, she checked again, and found that everything was normal, and she was about to hate the doctor. I'm not sure if you're really dead, you can calculate the time of your period, from the first day of your last period, see how many days have passed until now, and then draw conclusions. I'm really worried that I can change the hospital and have a look.

The diagnosis is only intrauterine early pregnancy, indicating that there are no other ** diseases. Intrauterine: non-ectopic pregnancy, early pregnancy: It should be early in pregnancy because you are only six weeks pregnant.

But the doctor said that the fetus is dead, and it costs more than 800 yuan to do a blood test? It's really dizzy,

Hello; The report says the size of the gestational sac. It has not yet developed into a fetus, so the sex is not visible. You can see it after three and a half months.

It cannot be judged by looking at the report alone, and needs to be analyzed in combination with clinical symptoms.

For example, when your ultrasound is done during the menstrual cycle is very important.

That is, how long is your menstrual cycle, and how many days after your menstrual period is clean?

At different stages of the menstrual cycle, the endometrial ovarian morphology is affected by estrogen, and the manifestations are different under B ultrasound.

After all, ultrasound is only a morphological observation, and it needs to be analyzed in combination with your age, marital and childbearing status, and clinical symptoms.

Judging from your supplement, you should be shortly after ovulation, there should be no big problem, and there is some information for you to refer to:

A normal ovarian ultrasound is an oval-shaped echo with a size of about 4x3x2 cm.

Follicles can be seen in the ovaries of women of childbearing age, and the size of the follicles varies with the menstrual cycle.

During hyperplasia, the ovaries increase in size. The follicle has a round or oval anechoic area with a smooth inner wall and well-defined borders. In the early stage of hyperplasia, multiple small follicles with a diameter of 3-5 mm can be seen in the ovarian cortex, and as the menstrual cycle progresses, the follicles gradually enlarge to form dominant follicles.

The follicle gradually matures, is more than 18 mm in diameter, round and full.

At the time of ovulation, due to the outflow of follicular fluid, a small amount of fluid can be observed in the rectal recess, which is often referred to in clinical practice as a liquid dark area. After ovulation, the wall of the follicle collapses, blood flows in, and the corpus luteum is formed.

Hello! First of all, I am a sonographer and will answer based on the information you provide!

The diagnosis is as follows:1Early pregnancy Because of the short gestational period, only the gestational sac is now visible, but the germ and primitive heart tube beats are not visible.

2.Cystic mass in the right adnexal area is likely to be a corpus luteum cyst, which means that the follicle does not rupture and ovulates, but grows up.

3.It is recommended that you go to the hospital again after 7-15 days for a follow-up ultrasound to see if there are any germs and original heart tube beats.

The report states that you are pregnant.

The uterus is of normal size and the wall is slightly thicker, indicating that the uterus has not been stretched out when you are pregnant, but the uterine wall will thicken when you are pregnant;

The anechoic dark area is the gestational sac, which means that it is not an ectopic pregnancy, and the gestational sac is too small to be distinguished, so it can only be an anechoic area;

An anechoic dark area of about the size of the right adnexal area can be seen in the right adnexal area, which is estimated to be a cyst.

No dark area of fluid in the pelvis: normal pelvis;

（02 07 11 27 *04+05+13+16+17+18+24+25+32-06+09

This is a two-color ball 4 guts 9 drag 2 blue number of the guts drag duplex ticket, the betting amount is = combin(9,2)*2*2=144 yuan.

It's normal to have a little soreness in the abdomen, but it's too strong to be checked by the House of Lords, so it is recommended to sell some twin products.

An anechoic dark area of about the size of the uterine cavity is visible, indicating that a pregnant woman is pregnant, but the gestational sac is not visible. Because 39 days is relatively small, a re-examination will show obvious fetal sacs after a week. The right adnexal area can be seen in an anechoic dark area of about the size of the cyst, consider it a cyst, don't worry too much, there are benign and malignant, no more than 5cm is not much of a problem, postpartum can be rechecked to reduce inflammation**, there is no dark area of fluid accumulation in the pelvis, indicating that there is no pelvic inflamatory disease, specifically that's it, now the child is still young It is not recommended to do B ultrasound, and it is best to do B ultrasound reexamination for about 3 months when the body is not uncomfortable, thank you.

It represents the double parietal diameter of the fetal head, which refers to the measurement of the diameter of both sides of the fetal head, and is also one of the indicators for estimating the size of the fetus. As a general rule, it is less than 3 cm at 3 months of pregnancy; After 5 months of pregnancy, the BPD is about 7 cm at 28 weeks (7 months), 8 cm at 32 weeks (8 months), and so on. After 8 months of pregnancy, it is normal to have an average weekly growth of about centimeters.

Femur length: It is the length of the fetal thigh bone, and its normal value is about 2-3 cm different from the BPD value of the corresponding pregnancy month, for example, the bpd is cm, and the femur length should be cm; bpd is centimeters, femur length should be centimeters, etc. The data you provided is normal

The fetal heart rate is normal at 120-160 per minute.

4.Fetal movement: Yes and strong are normal, no and weak may be the fetus in sleep, or it may be abnormal, which should be comprehensively analyzed in combination with other items.

5.The placenta is located in the anterior wall of the uterus, about thick, placental grade II. , means that it has begun to mature, the placenta is used 0, 1, 2, 3 to represent the maturity, 0 is the earliest, 1 is just beginning to mature, your 2 means that it is quite mature, and 3 generally requires that it must be produced.

Amniotic fluid index refers to the condition of amniotic fluid, 160, which is very good...

A "U" shaped indentation can be seen in the fetal neck: it is the umbilical cord around the neck, the U-shaped indentation is that the umbilical cord is concave in the child's neck, and the image shape of the longitudinal section of the fetal neck is U-shaped.

BPD is the double parietal diameter of the fetal head.

FL is the fetal femur length diameter.

If it is an abdominal ultrasound, the examination is the influence structure of the hepatobiliary, pancreatic, spleen, and kidneys.

It mainly depends on whether there is organic damage.

Such as fatty liver, liver cyst, hepatoma, cholecystitis, gallstones, splenomegaly, kidney stones, kidney cysts and so on.

B-mode ultrasound diagnosis technology has been used in clinical medicine for more than 20 years, and scientific research has proved that B-mode ultrasound examination is not harmful to the fetus and pregnant women. In experiments on animals with B-type ultrasound, two groups of pregnant animals who did not receive ultrasound were compared and observed and found no significant difference in the incidence of malformations in their offspring. The same finding was found in medical clinical observations, and the fetal malformation rate of pregnant women who had undergone B-mode ultrasound did not increase significantly compared with that of pregnant women who had not undergone B-type ultrasound.

This is because the dose of ultrasound used for diagnosis in the human body is quite small, and the examination time is not long, which is not enough to cause some damage to the tissues and organs of the human body. Therefore, B-type ultrasound is an effective examination method that can be repeated with high safety, strong reliability, easy to use, and does not cause any pain to the examiner.

B-mode ultrasound is used in different aspects of pregnant women, and there are different types of examinations.

The application of B-ultrasound for prenatal examination is an important means of prenatal diagnosis. Ultrasonography during pregnancy can detect the following indicators: determine the place where the placenta is attached.

The placenta in its normal position attaches to the anterior, posterior, lateral, or fundus of the uterus. B-mode ultrasonography can be used to confirm the presence of abnormalities.

Determine placental maturity grade.

There are four levels of placental maturity: grade 0, grade, grade, and grade. Class I marks basic maturity of the placenta; grade markers of placental maturation; The placenta is aging, and the placenta's ability to transport oxygen and nutrients is reduced due to calcification and cellulose, and the life of the fetus is threatened at any time.

There is currently no consistent standard for determining the amount of amniotic fluid in which the amount of amniotic fluid is determined. In the United States, ultrasonography is performed to estimate the amount of amniotic fluid to be high, medium, or low based on visual observation alone. Tianjin Central Obstetrics and Gynecology Hospital calculates the average amount of amniotic fluid in the neck, abdomen, and back of the buttocks.

At term, the average amount of amniotic fluid is 4 5 cm; The mean amniotic fluid volume is greater than or equal to 6 cm, which means that there is more amniotic fluid; More than or equal to 8 cm is polyhydramnios, which may be combined with fetal malformations; less than or equal to 3 cm for less amniotic fluid; Less than or equal to 2 cm is oligohydramnios, indicating that the placenta is underfunctioned, and the fetus is at risk of dying in utero, and the appropriate time should be selected to induce labor, or cesarean section to rescue the fetus.

Fetal position B ultrasound can measure the position of the fetus in the uterine cavity - "fetal position", to know whether the fetal head enters the pelvis or floats on the pubic surface.

Fetal head double parietal diameter (bpd).

There is a maximum transverse diameter of the fetal head.

The fetus has a long roof and hips.

The length between the top of the fetus and the tip of the breech is the "parietal-hip length". This length is related to the length and weight of the fetus. In general, the longer the top hip length, the longer the body length and the corresponding heavier the weight.

Ultrasound can also be used to measure the overall volume of the fetus, the volume of the fetus viscera (heart), or the placenta to determine fetal maturity.

In addition to detecting these contents, the life of the fetus in the womb can also be visualized through the fluorescent screen of ultrasound. For example, the fetus swallows amniotic fluid, the beating of the heart, the movement of the chest rises and falls, the gradually full bladder, and the discharge of urine.

There are many places where B ultrasound can be inspected, and it is possible.

To check for diseases of many organs, all hospitals have long regarded ultrasound as a routine examination item. B-ultrasound can be used to examine most organs in the body, such as the parotid gland, thyroid, submandibular gland, pancreas, prostate and other glands, and then to perform internal organ examinations, such as liver, heart, spleen, gallbladder, etc. There are also examinations of urinary organs, such as kidneys, ureters, bladder, and ** examinations, such as uterus, fallopian tubes, ovaries, etc.

In addition, ultrasound is also widely used in prenatal examination for pregnant women, which can monitor the growth and development of the fetus and the examination of fetal abnormality.

B ultrasound examination can be used for the examination of all solid organs of the abdominal organs, including the liver, spleen, kidneys, and is also often used for the examination of gynecology and reproductive system, such as uterus and ovaries, male prostate, and also suitable for the examination of superficial organs thyroid, muscle, breast, and can also be used for the examination of the heart and the examination of blood vessels.

Deformity examination refers to the examination carried out by a woman in the early stage of pregnancy in a hospital or maternal and child health station to rule out the possibility of a malformed fetus. B ultrasound check the baby's facial features, limbs and internal organs for abnormalities, blood and urine tests are general routine examinations, mainly to see whether there is anemia.
