What does color Doppler ultrasound mainly check?

When going to the hospital for a check-up, many doctors will ask patients to undergo color ultrasound examinations. Most of the patients undergoing color ultrasound examinations are female friends, but some male friends will also be asked by doctors to undergo color ultrasound examinations. Many people don’t quite understand what diseases color ultrasound can detect, and whether doing it too often will have an impact on the body. Next, I will explain to you what diseases color ultrasound is mainly used to examine and its advantages.

1. Color Doppler ultrasound is the main method for early diagnosis of fetal and maternal diseases before delivery. The diagnostic accuracy rate of acute abdominal diseases in obstetrics and gynecology is significantly higher than that of black and white ultrasound, such as ectopic pregnancy, incomplete abortion, adnexal inflammatory mass, intrauterine blood clot, ovarian tumor pedicle torsion, etc.;

2. Diagnosis of cardiovascular diseases such as heart valve disease, congenital heart disease, cardiomyopathy, cardiac tumors, cervical large vessel disease, chest and abdominal large vessel disease, occlusion and thrombosis of large vessels in the limbs, aneurysm, etc. It also has a high diagnostic value for coronary heart disease, arrhythmia and cor pulmonale;

When modern people go to the hospital for illness, many hospitals will recommend color ultrasound in order to have a better understanding of the condition. So what does color ultrasound check? Do you know the difference between color ultrasound and B-ultrasound? In fact, color ultrasound has many advantages. First of all, it can clearly and intuitively reflect the condition!

3. It helps to distinguish arteries and veins.

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

5. It helps to understand the nature of blood flow.

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

7. Can reliably detect shunts and reflux.

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

9. Color ultrasound has higher resolution than B-ultrasound, more functions, and a more detailed and wider examination range and content.

1. Color ultrasound is simply a high-definition black and white B-ultrasound plus a color Doppler. It has the advantages of two-dimensional ultrasound structural images and provides rich information on hemodynamics. It can be understood this way: the range of color ultrasound is larger than that of black and white B-ultrasound. Ordinary B-ultrasound is like a black and white photo; two-dimensional color ultrasound is not a color photo. The left picture generally shows the condition of the uterus in black and white, and the fetal image on the right will have red and blue to show blood vessel information; three-dimensional color ultrasound looks khaki; and four-dimensional B-ultrasound is a VCR taken by a camera.
