The difference between color ultrasound and B-ultrasound

Many pregnant mothers will encounter a problem when doing prenatal check-ups, which is that they don’t know the difference between color ultrasound and B-ultrasound. In fact, although color ultrasound and B-ultrasound are both used to check fetal development, there are some differences in the conditions they show. Moreover, with the development of technology, we now have four-dimensional color ultrasound, which can show the specific condition of the fetus in detail when doing fetal examination.

In fact, the so-called B-ultrasound is the most common examination result displayed in black and white, while the results displayed by color ultrasound are clearer. In addition, there will be certain differences in their prices. The functional differences between color ultrasound and B-ultrasound are as follows:

Simply put, high-definition black and white B-ultrasound plus color Doppler has the advantages of two-dimensional ultrasound structural images and provides rich hemodynamic information at the same time. It can be understood this way: ordinary B-ultrasound is like a black and white photo, color B-ultrasound is like a color photo, and three-dimensional B-ultrasound is like a VCR shot by a camera. Ordinary B-ultrasound and color B-ultrasound only show a flat surface, while 3D B-ultrasound shows a three-dimensional image of the fetus, which can show the front, back, left, right, top and bottom of the fetus, and is more comprehensive, real and clear.

The main advantages of color Doppler ultrasound are:

①It can quickly and intuitively display the two-dimensional plane distribution state of blood flow.

②It can show the direction of blood flow.

③It is helpful to distinguish arteries and veins.

④Color Doppler ultrasound is helpful in identifying vascular and non-vascular lesions.

⑤It is helpful to understand the nature of blood flow.

⑥It is convenient to understand the phase and speed of blood flow.

⑦ Can reliably detect shunt and reflux.

⑧It can quantitatively analyze the origin, width, length and area of ​​the blood flow beam.

Color ultrasound has higher resolution than B-ultrasound, more functions, and a detailed and wider examination range and content. Modern color ultrasound has completely replaced B-ultrasound.

Precautions

B-ultrasound is a medical examination item that patients often encounter when they visit the doctor. In clinical practice, color ultrasound is widely used in the diagnosis of cardiology, gastroenterology, urology, and obstetrics and gynecology diseases.

Knowing the difference between color ultrasound and B-ultrasound, pregnant mothers must pay attention that not every examination requires color ultrasound. For example, in the early stages, the use of black and white B-ultrasound has less impact on the fetus. As the fetus gradually develops, color ultrasound will be used to better show the fetus's current condition.
