Should make color or black and white ultrasound?

Ultrasound has become an increasingly popular means of health examination, sometimes without the need for a doctor. Besides black and white ultrasound, color ultrasound or Doppler technology has become very popular and seems to be encroaching on black and white ultrasound in diagnosis.

One day, take me to the ultrasound room at a private facility on Nguyen Kiem Street for a general examination.

Here, the receptionist, who knew me only the black and white ultrasound, suggested: 'Why don't you have an ultrasound for the clear image, what does black and white see?'. Wondering what kind to choose, one doctor sitting next to me added: the doctor told me to go for an ultrasound but did not say whether it was colored or black and white. more clearly so that the doctor can look at it and treat it properly.

Because of the persuasion, most of the patients initially were only black-and-white, but then turned to color despite the price being three times higher!

This issue was explained by Dr. Nguyen Quang Thai Duong - Ho Chi Minh City University of Medicine and Pharmacy:

The situation of Doppler ultrasound in Ho Chi Minh City is currently very messy. Many ultrasound facilities have misused new techniques to commercialize wastefulness for patients. Taking advantage of the patients' ignorance, many ultrasound clinics still suggest patients to do so even if the disease does not require Doppler.

Doppler ultrasound is a type of ultrasound that requires a high technique but is not as modern as it should be, but must be directed by a physician.

Because it is a high-tech ultrasound, it is necessary to have an ultrasound doctor trained properly. Currently, in Ho Chi Minh City, there are only a few doctors who have been trained on Doppler ultrasound. Even as Ho Chi Minh City University of Medicine and Pharmacy has a team of 20 ultrasound doctors, there are only 3 people who have been trained in Doppler ultrasound.

Although not trained in Doppler ultrasound, but before the trend, patients like color ultrasound, so some ultrasound-based ultrasound facilities have changed color screens and charged 3 times higher for patients. While they themselves do not know what color ultrasound to serve, even on color ultrasound images is no different from the black and white ultrasound.

- Is Doppler ultrasound better than black and white ultrasound?

- To answer this question, Dr. Thai Duong also added: It is definitely better but not any parts survey needs to have Doppler ultrasound. Dopper ultrasound is used to investigate and detect pathologies:

Evaluate cardiac diseases. Vascular diseases when suspected to have narrowing or vascular occlusion in the body, to detect and prevent seizures, blood clots in the brain clog blood vessels that cause stroke. However, Doppler ultrasound can only detect blood vessels of average size or higher.

- Organ transplant: assess blood vessels to feed grafting organs like kidney, liver transplant is normal?

- Evaluate circulatory diseases in the body like cirrhosis.

According to the image learning formula, not every color ultrasound has to be colored because in fact sometimes the ultrasound image is shown on the black and white image but still the Doppler technique, on the contrary, not just the color. Doppler.

Because of this confusion, many patients have been abused by some ultrasound facilities. According to the survey, most of the current private ultrasound facilities only remove color to charge, not to make this technique.

According to Dr. Thai's advice, Doppler ultrasound is a difficult technique, not all ultrasound facilities are qualified to do, especially liver Doppler ultrasound is difficult, private facilities are rarely available. So, in order to avoid useless waste, patients should only do Doppler ultrasound when ordered by a treating doctor and must choose a reputable place. For general abdominal examination, gynecology . just plain white ultrasound is enough.
