What can color Doppler ultrasound check?

Color ultrasound is a relatively common examination instrument. It can be used to examine many diseases. For example, for pregnant women, during the examination process, it can be found whether the fetus is developing normally and whether there are any disease problems. For women, it can check whether there is gynecological inflammation or some lumps. In addition, there are many examinations for cardiovascular diseases, such as heart valve disease, congenital heart disease, etc.

What does color Doppler ultrasound check?

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;

3. Examination of abdominal organs: liver, biliary system, spleen, pancreas, kidneys, ureters, bladder, prostate, seminal vesicles, adrenal glands and digestive system;

4. Thyroid and parathyroid diseases: including goiter, thyroiditis, thyroid tumors, or those with positive laboratory tests, those with unexplained swelling in the front of the neck; those with hoarseness due to thyroid tumor compression, renal failure or abnormal blood calcium and phosphorus metabolism can all undergo color Doppler ultrasound examination;

5. Color Doppler ultrasound examination of body surface tumors: an important examination method for diseases of the neck, breast, scrotum and testicles, maxillofacial area and some muscle tissues.

Advantages of Color Doppler Ultrasound

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

2. It can show the direction of blood flow.

3. It helps to distinguish arteries and veins.

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

The difference between color ultrasound and B-ultrasound

Simply put, color ultrasound is high-definition black and white B-ultrasound plus color Doppler. It has the advantages of two-dimensional ultrasound structural images and at the same time provides rich information on hemodynamics. It can be understood in 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 plane, while three-dimensional B-ultrasound shows a three-dimensional image of the fetus. It can see the front, back, left, right, top and bottom of the fetus, which is more comprehensive, real and clear.

B-ultrasound is a medical examination item that patients often come into contact with 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.

Generally speaking, the radiation from color ultrasound is greater than that from black and white B-ultrasound. Doctors usually do not do color ultrasound in the early stages of pregnancy. They will do black and white B-ultrasound to determine the fetal pregnancy status. Black and white B-ultrasound has less radiation to the fetus. Color Doppler Ultrasound will be done in the mid-term.

Therefore, the choice of B-ultrasound and color ultrasound examination during pregnancy should be based on the actual situation. The most advanced one now is four-dimensional color ultrasound, which has high clarity and high safety.
