How is color Doppler ultrasound performed

Color ultrasound is a very common examination method in clinical medicine. Many people will do color ultrasound examinations when necessary. For example, pregnant women will use color ultrasound examinations to determine the development of their children. There are two main types of color ultrasound: three-dimensional color ultrasound and four-dimensional color ultrasound. There are many items that can be checked by color ultrasound. Below, we will introduce you to the relevant knowledge of color ultrasound in detail!

1. 3D Color Doppler Ultrasound

Three-dimensional color ultrasound is a type of color ultrasound, and it provides three-dimensional dynamic display. The advantages of three-dimensional color ultrasound are mainly reflected in its high sensitivity and display rate to uterine artery and ovarian blood flow. ②Shorten the inspection time and obtain accurate Doppler spectrum. ③No need to fill the bladder. ④Not affected by body type obesity, abdominal scars, intestinal gas distension, etc. ⑤ Use the movement of the probe tip to find the tenderness of the pelvic organs to determine whether there is pelvic adhesion.

Three-dimensional color ultrasound surface imaging is used in obstetric examinations. It can not only observe the growth process of the fetus, but also check the changes in the placenta, amniotic fluid and umbilical cord. More importantly, it can be used as the main means of diagnosing fetal malformations. Due to the large grayscale contrast between tissue structure and liquid, the three-dimensional morphology, surface features, and spatial position relationship of the suspicious structure can be clearly displayed, providing a three-dimensional image of the fetus in the uterus. Three-dimensional reconstruction includes surface imaging, transparent imaging and multi-plane imaging modes.

2. 4D Color Doppler Ultrasound

The four-dimensional color ultrasound diagnostic instrument is currently the most advanced color ultrasound equipment in the world. "4D" is the abbreviation of "four dimensions". The fourth dimension refers to the vector of time. For ultrasound, 4D ultrasound technology is a recently developed technology and is also the exclusive technology of Canada's Yousheng Company. 4D ultrasound technology uses 3D ultrasound images plus time dimension parameters. This revolutionary technology enables real-time acquisition of three-dimensional images, surpassing the limitations of traditional ultrasound. It offers a wide range of applications including abdominal, vascular, small parts, obstetrics, gynecology, urology, neonatology and pediatrics. The result: real-time, dynamic images of your unborn baby or other internal organs.

Compared with other 3D ultrasound diagnostic processes, 4D ultrasound allows doctors to observe the dynamic movement of internal organs in real time. For example, doctors can judge the development of the fetus based on its movements, and the accuracy of puncture under ultrasound guidance can be improved by observing the three-dimensional movement of the puncture needle. Therefore, clinicians and ultrasound doctors can detect and find various abnormalities.

3. Color Doppler Ultrasound Examination Items

Circulatory system: heart, brain, limbs, and blood vessel diseases

Digestive system: liver, gallbladder, spleen, stomach, abdominal diseases

Urinary system: various diseases of kidney, ureter and bladder

Glandular: thyroid, breast, pancreas, prostate various diseases

Gynecology: uterus, ovaries, fallopian tubes, pelvic diseases

Obstetrics: The condition of the fetus, fetal head, fetal heart rate, placenta, umbilical cord, and amniotic fluid can determine whether there are any deformities, placenta previa, or umbilical cord around the neck.
