The difference between four-dimensional color ultrasound and ordinary color ultrasound
Four-dimensional color Doppler ultrasound provides a variety of applications in the fields of abdomen, vasculature, small organs, obstetrics, gynecology, fetal color Doppler ultrasound, urology, neonatal and pediatrics. The result: the ability to display live, dynamic images of an unborn baby or other internal organs of the human body. Compared with other ultrasound diagnostic procedures, it can observe the dynamic movement of the internal organs of the human body in real time. Clinicians and sonographers can detect and detect abnormalities ranging from vascular malformations to genetic syndromes. Four-dimensional color Doppler ultrasound can observe the growth and development of the fetus in the womb from multiple directions and angles, providing accurate scientific basis for the early diagnosis of fetal congenital surface malformations and congenital heart disease. In the past, B-ultrasound equipment could only check the physiological indicators of the fetus, while 4D color ultrasound can also check the fetal body surface, such as cleft lip, spina bifida, brain, kidney, heart, bone dysplasia, etc., for early treatment. Having a smart and healthy baby is no longer a fantasy. Make the baby\’s appearance and movements into photos or VCDs, so that your baby can have the most complete 0-year-old photo album. In addition, the four-dimensional color ultrasound diagnostic instrument has excellent ergonomic design, no radiation, no light waves, and no electromagnetic waves, and has no impact on human health.
Application scope of four-dimensional color ultrasound
Four-dimensional color Doppler ultrasound is currently the most advanced color Doppler ultrasound equipment in the world. It offers a wide range of applications including abdominal, vascular, small parts, obstetrics, gynecology, urology, neonatology and pediatrics. The result: the ability to display live, dynamic images of an unborn baby or other internal organs of the human body.
The difference between three-dimensional color ultrasound and four-dimensional color ultrasound
Color Doppler Ultrasound, 3D Color Doppler Ultrasound, and 4D Color Doppler Ultrasound. Color Doppler ultrasound is actually black and white, but 3D and 4D color Doppler ultrasound may only have khaki color when the 3D and 4D images are generated. This does not mean that color Doppler ultrasound is in color. It\’s called a color Doppler ultrasound because indicators such as heart and blood flow are color-coded. The resolution of color Doppler ultrasound is higher than that of ordinary black and white B-ultrasound, so more doctors are willing to use color Doppler ultrasound for more detailed examinations. And because the blood flow can be marked with color, when the umbilical cord is wrapped around the neck, you will see a U-shaped or W-shaped blood flow on the baby\’s neck, and it is clear at a glance whether the umbilical cord is around the neck. 3D color Doppler ultrasound and 4D color Doppler ultrasound images are generated later. This does not mean that the observed image is 3D or 4D. Ordinary color Doppler ultrasound is still used for observation, and then the observed planar image is converted into 3D through the conversion software in the instrument. Four-dimensional stereoscopic images, to put it bluntly, means that by installing similar software on your computer at home, you can convert ordinary B-ultrasound images into three-dimensional images at home. In a diagnostic sense, 3D color Doppler ultrasound and 4D color Doppler ultrasound are not very helpful in diagnosis, but people who do not understand B-ultrasound images can also see the symptoms. Their significance is that they allow you to see what the fetus looks like in the womb. 3D color ultrasound and 4D color ultrasoundThe difference lies in the \”time dimension\”, that is to say, 3D color ultrasound is a picture, and 4D color ultrasound is a video, allowing pregnant mothers to see a series of fetal movements. 4D color ultrasound is dynamic, while 3D color ultrasound is static, so 4D color ultrasound will look clearer. 3D Doppler Doppler ultrasound can only be a picture at a certain point in time. 4D Doppler Doppler ultrasound can be played back continuously like DV and can be burned to a disc. Three-dimensional color Doppler ultrasound and high-definition four-dimensional color Doppler ultrasound have the same effect of eliminating abnormalities, and high-definition four-dimensional color Doppler ultrasound is more accurate.
Comparison of the advantages of four-dimensional color ultrasound and three-dimensional color ultrasound
Four-dimensional ultrasound
Ability to determine fetal age
Can evaluate multiple births or high-risk pregnancies
Analyze fetal development
Detecting placental abnormalities
Can detect abnormal pregnancies such as ectopic pregnancy
Can detect structural abnormalities of the uterus
Ability to locate the placenta
Can detect fetal abnormalities
Can detect abnormal bleeding
Can detect ovarian tumors and fibroids
It can observe the growth and development of the fetus from multiple directions and angles, providing scientific basis for the early diagnosis of fetal congenital surface malformations and congenital heart disease.
It can automatically take photos and dynamic videos of the fetus in the womb, or real-time moving images of the internal organs of the human body.
Three-dimensional color Doppler ultrasound
Three-dimensional color Doppler ultrasound is a color Doppler ultrasound diagnostic instrument with three-dimensional dynamic display. Its function is the same as ordinary color Doppler ultrasound. Simply put, color Doppler ultrasound is high-definition black and white B-ultrasound plus color Doppler. Three-dimensional color Doppler Doppler Doppler Doppler Doppler Doppler Doppler Doppler Doppler Doppler Doppler Doppler Doppler Doppler Doppler Doppler Doppler Doppler Doppler Doppler Doppler Doppler Doppler Doppler Doppler Doppler Doppler The main advantages of Doppler Doppler Color Doppler ultrasound in obstetrics and gynecology are the identification of benign and malignant tumors, umbilical cord diseases, fetal congenital heart disease, and placental function. evaluation of. Spectral observations can also make diagnoses that are extremely difficult to distinguish between black and white.
Vaginal probe three-dimensional color ultrasound has certain advantages over abdominal exploration. Its advantages are mainly reflected in:
Uterine arteries and ovarian blood flow are sensitive and highly visible.
Shorten inspection time and obtain accurate Doppler spectrum.
No need to fill your bladder.
Does not interfere with obesity, abdominal scars, intestinal distension, etc.
Use the movement of the probe tip to find tender areas in the pelvic organsposition to determine whether there are adhesions in the pelvic cavity.
Three-dimensional color Doppler ultrasound body surface imaging is used for obstetric examinations. It can not only observe the growth process of the fetus, but also visually see the activities of the fetus in the mother\’s body, such as breathing and movement, including the size of the entire body. Movements, movements of limbs, and even small swallowing movements of the fetus. The doctor can also observe whether the fetal tone is good through B-ultrasound. Usually, when the fetus suffers hypoxic injury in the womb, the fetus\’ mobility will be significantly reduced or eliminated. It is difficult to detect these changes without a B-ultrasound. Its advantages are:
(1) On the basis of retaining two-dimensional imaging, coronal section images are added.
(2) Stereopositioning, axial adjustment, and the ABC three-axis plane can be adjusted arbitrarily until the best image is displayed.
(3) Three-dimensional imaging, dynamic and intuitive; real-time dynamic observation of fetal head, body surface and internal organ activities, the image is clear, accurate and reliable.
(4) Cropping function can maintain the focus of the image; cut off useless parts, and perform 3D reconstruction and display of suspicious parts.
(5) Rotation function for multi-directional observation; it has a 360-degree rotation function of front and back, left and right, and up and down to observe images from different directions in all directions.
(6) Can be given to fetus
Take beautiful photos, record changes in expressions, and burn discs to save as data for a permanent souvenir.
(7) It can display the three-dimensional relationship and adjacent relationship of lesions at different levels. The application of three-dimensional color ultrasound in obstetrics provides a wealth of image information for clinical ultrasound diagnosis. The fetus is surrounded by fluid in the amniotic cavity, which is a good imaging condition for three-dimensional ultrasound. The image is three-dimensional and intuitive, and the angle can be adjusted arbitrarily. Through three sections, Suspicious structures can be observed by rotation, and malformations of the fetal gross structure can be clearly seen at a glance, which greatly improves the quality of diagnosis and treatment and reduces misdiagnosis or missed diagnosis.
