Four-dimensional color Doppler ultrasound left ventricle bright spot

People's heart function is originally a very critical position. At this time, it is not only very important, but also very powerful. The strong light spot in the left atrium of the four-dimensional color ultrasound is a judgment made by people during the examination. When doing the examination, for such professional numbers, many people do not know how to express them, nor do they know what the problem is. Here I will introduce to you some types of four-dimensional color ultrasound and what they mainly detect?

Four-dimensional B-ultrasound

Fetal sac: also called gestational sac. For women who have regular menstruation of 28-30 days, the gestational sac can be seen in the uterine cavity by B-ultrasound after 35 days of amenorrhea. The diameter of the gestational sac is about 2 cm at 6 weeks of pregnancy and about 5 cm at 10 weeks of pregnancy. It is normal for the gestational sac to be located at the fundus, front wall, back wall, upper part, or middle part of the uterus; it is normal for it to be round, oval, and clear in shape; if the gestational sac is irregular in shape, blurred, and located in the lower part, and the pregnant woman also has abdominal pain or vaginal bleeding, she may have a miscarriage.

Fetal head: A complete outline is normal, defects or deformations are abnormal, and no displacement of the brain midline and no hydrocephalus are normal.

"4D" is the abbreviation of "four dimensions". The fourth dimension refers to the vector of time, so it is also called real-time three-dimensional. For ultrasound, 4D ultrasound technology is a revolutionary breakthrough in the color ultrasound industry. It was first developed and promoted by Madison Corporation in South Korea. 4D ultrasound technology uses 3D ultrasound images plus time dimension parameters. This revolutionary technology can acquire three-dimensional images in real time, surpassing the limitations of traditional ultrasound. It offers a wide range of applications including abdominal, vascular, small parts, obstetrics, gynecology, urology, neonatology and pediatrics.

Fetal heart rate: Fetal heart rate can be seen by B-ultrasound at 7-8 weeks of pregnancy, and at the earliest at the 6th week of pregnancy. The normal fetal heart rate is between 120-160 beats per minute.

Umbilical cord: Under normal circumstances, the umbilical cord should float in the amniotic fluid. If the umbilical cord image is seen on the fetal neck, the umbilical cord may be wrapped around the neck.

Amniotic fluid: The vertical depth of the maximum amniotic fluid pool is normal between 3-7 cm. More than 7 cm indicates increased amniotic fluid, and less than 3 cm indicates decreased amniotic fluid.

Placenta: Position refers to the location of the placenta in the uterine wall. The thickness of a normal full-term placenta should be between 2.5-5 cm.

Advantages

Four-dimensional color ultrasound provides a wide range of applications including abdomen, blood vessels, small organs, obstetrics, gynecology, urology, neonatology and pediatrics. The result: real-time, dynamic images of your unborn baby or other internal organs.

Compared with other ultrasonic diagnostic processes, the dynamic movement of internal organs of the human body can be observed in real time. Clinicians and sonographers can detect and identify a variety of abnormalities, from vascular malformations to genetic syndromes. Four-dimensional color ultrasound can observe the growth and development of the fetus in the uterus from multiple directions and angles, and can provide an accurate scientific basis for the early diagnosis of congenital surface malformations and congenital heart diseases of the fetus. In the past, B-ultrasound equipment could only check the physiological indicators of the fetus, but four-dimensional color ultrasound can also examine the fetus's body surface, such as cleft lip, spina bifida, and maldevelopment of the brain, kidneys, heart, and bones, so as to provide treatment as early as possible. It is no longer a fantasy to give birth to a smart and healthy baby, and to make photos or VCDs of the baby's appearance and movements so that the baby has the most complete 0-year-old photo album.
