Four-dimensional color ultrasound can observe the whole picture of the fetus three-dimensionally and directly detect the limbs and internal organs of the fetus. Therefore, clinically, doctors recommend that pregnant women use four-dimensional color ultrasound to perform fetal ovulation in the second trimester. Abnormal examination. However, what should I do if the four-dimensional color ultrasound shows that the gallbladder is slit-shaped? What should I do if four-dimensional color ultrasound shows that the gallbladder is slit?
Four-dimensional color ultrasound is currently the most advanced color ultrasound equipment in the world. 4D ultrasound technology uses 3D ultrasound images plus time dimension parameters to obtain three-dimensional images in real time. It provides a wide range of applications including abdominal, vascular, small organ, obstetrics, gynecology, urology, neonatal and pediatrics.
In obstetrics, four-dimensional color ultrasound performs real-time four-dimensional examination of the fetus, allowing doctors to judge the development of the fetus based on the movement of the fetus. Observation of the three-dimensional movement of the puncture needle can improve the performance of punctures under ultrasound guidance. accuracy. So clinicians and sonographers can detect and detect a wide range of abnormalities, from vascular malformations to genetic syndromes.
Four-dimensional color ultrasound can not only see the whole picture of the fetus in the middle and late pregnancy three-dimensionally, directly detect the limbs and internal organs of the fetus, but also clearly display the real-time dynamics and moving images of the fetus as well as the baby’s movements in the mother’s belly. Various expressions; it can also three-dimensionally display the development of various fetal organs, so as to detect some congenital malformations as early as possible, such as early diagnosis of fetal cleft lip, cleft palate, abnormal bone development, cardiovascular malformations, etc.
Generally speaking, four-dimensional color Doppler ultrasound can detect major fetal malformations, such as neonatal congenital heart disease, cleft lip and palate, hydrops, polydactyly (toes) and external ear malformations. find out. However, four-dimensional color Doppler ultrasound is not omnipotent. For example, newborn deafness and cataracts cannot be detected.
If the four-dimensional color ultrasound shows that the gallbladder is slit-shaped, it may be that the fetal gallbladder has not developed well, and further examination is required. What should we pay attention to in four-dimensional color ultrasound?
1. The best time for four-dimensional color ultrasound examination is between 24 and 30 weeks of pregnancy for single fetuses, and between 22 and 23 weeks for twins. Because the fetal structure has been formed during this period, the size of the baby and the amniotic fluid are moderate, the space for movement in the womb is large, the echo of the fetal bones is relatively small, and the examination image is relatively clear. If the inspection time is too early, the best inspection effect cannot be achieved.
2. Traditional B-ultrasound requires fasting and holding urine before testing. However, whether you need to hold in your urine to do a four-dimensional color ultrasound depends on your gestational age. You need to hold your urine when you are younger, but you don’t need to hold your urine when you are older. Generally, you don’t need to hold your urine when you are four months pregnant to do a four-dimensional color ultrasound. . Half an hour before the four-dimensional color ultrasound, it is recommended that the expectant mother eat something and drink some water, which can increase fetal movement.
3. Before the four-dimensional color ultrasound examination, pregnant women should wear comfortable and loose clothing. It is best to wear their tops and trousers separately to facilitate the examination. In the four-dimensional color ultrasound examination, the doctor mainly uses the examination instrument to check the current facial development of the fetus, as well as whether there are any developmental defects in the heart, brain, spine, etc. If it is found during the examination, If the fetus shows abnormality, the examination may take a relatively long time. Generally, the entire inspection process will take about 30 minutes.
4. Four-dimensional color Doppler ultrasound can observe the growth and development of the fetus in the mother-to-be’s abdomen from multiple directions and angles, providing a more accurate basis for early diagnosis of fetal congenital surface malformations and other diseases. For example, cleft lip, spina bifida, brain, kidney, heart, skeletal dysplasia and other abnormalities can be detected in time, so that early treatment can be carried out to increase the chance of eugenics. However, due to the limitations of ultrasound technology, all fetal malformations cannot be detected, that is, the ultrasound diagnosis accuracy rate cannot reach 100%.
Wonderful recommendations: Amniocentesis for ectopic pregnancy, four-dimensional color ultrasound, Down syndrome screening, varicose veins, false contractions, will cause breathing difficulties? Will the baby move during contractions? Symptoms of pregnancy and giving birth to a boy, B-ultrasound examination of fetal gender percentage Is it accurate?
