Which one has greater radiation, B-ultrasound or color ultrasound

B-ultrasound and color ultrasound are two ways to check the body. Generally, pregnant women need to do both of these examinations during pregnancy. However, these two examinations also have certain radiation. For special groups such as pregnant women, they should pay more attention to this problem. However, these examinations cannot be avoided, otherwise it is very likely to cause fetal maldevelopment due to carelessness. So which one has greater radiation, B-ultrasound or color ultrasound?

What is the difference between color ultrasound and B-ultrasound

The main difference between color ultrasound and B-ultrasound is not as simple as that between color TV and black and white TV. The so-called color ultrasound is the abbreviation of color Doppler ultrasound (Color Doppler Ultasound), and B ultrasound is the abbreviation of B-mode ultrasound (B-Mode Ultasound). Color ultrasound and B-ultrasound are two completely different instruments, not the simple color difference between color TV and black and white TV as people imagine. Color ultrasound is not color B-ultrasound. The main technical indicators of color ultrasound, such as (number of probe chips, number of imaging channels, imaging dynamic range, host processing power and depth, etc.) are much higher than those of B-ultrasound. Therefore, it can significantly improve image resolution, detect smaller lesions earlier, improve the early diagnosis rate of the disease, and more clearly display the details of the changes around and inside the lesions, thereby improving the accuracy of diagnosis. Color Doppler flow imaging (Color Doppler Flow Imaging) function can display the vascular anatomical structure, blood flow direction, blood flow velocity and blood flow status changes in the diseased area, which can significantly improve the ability to identify diseases and improve the accuracy of diagnosis. Color Doppler ultrasound has tissue harmonic imaging function, which can significantly reduce interference from obesity, gas and other artifacts and improve image clarity. Color Doppler ultrasound has the function of contrast agent harmonic imaging, which can perform acoustic contrast imaging and conduct more in-depth examination and research on lesions. Some color Doppler ultrasounds also have certain special functions, such as myocardial motion velocity analysis and four-dimensional imaging, which can perform more in-depth quantitative analysis of lesions. Therefore, color ultrasound examination can detect lesions earlier and can make differential diagnosis of lesions more accurately, significantly improving the accuracy of diagnosis. However, the missed diagnosis rate and misdiagnosis rate of B-ultrasound examination are significantly higher than those of color ultrasound.

Which one has greater radiation, color ultrasound or B-ultrasound?

Relatively speaking, color ultrasound has greater radiation than B-ultrasound. However, the relevant examinations done for pregnant women at different stages of prenatal examinations are also different. The most common regular examination is B-ultrasound. B-ultrasound is used to diagnose diseases and observe fetal development (in order to exclude deformed babies), while color ultrasound can not only be used to diagnose diseases and observe fetal development, but also observe the distribution of fetal blood vessels (which can be used to calculate blood resistance) and see if the fetus is suffering from hypoxia in the uterus. Therefore, color ultrasound radiation is relatively greater. Pregnant women should not be afraid of B-ultrasound examinations. Correct regular prenatal B-ultrasound examinations can also ensure the normal development of the fetus and have no effect on human health.

What can B-ultrasound detect?

Gynecological B-ultrasound has two types: abdominal B-ultrasound and vaginal B-ultrasound. Let's take a look at what B-ultrasound can check:

The main uses of abdominal B-ultrasound are as follows:

1. Routine gynecological examination: observe the size of the ovaries, the presence of cysts, solid tumors, etc., and also observe the presence of uterine fibroids, adenomyosis, endometriosis, and endometrial polyps.

Note: Ultrasound cannot diagnose atypical endometrial hyperplasia or endometrial cancer, and diagnostic curettage or endometrial biopsy is required for screening.

2. Early pregnancy diagnosis and pregnancy check-up.
