What is Doppler ultrasound?
Doppler ultrasound is used to measure blood flow and blood pressure. During this ultrasound, high-frequency sound waves (ultrasound) are used to collide with the red blood cells and after returning, they show it as Doppler ultrasound. Doppler ultrasound can measure the speed of blood flow.
Doppler ultrasound helps to diagnose the following problems:
blood clotting
Weak functioning of the veins in the leg veins (venous insufficiency)
Heart valve defects and congenital heart diseases
Arterial occlusion
Decreased blood flow to the legs (peripheral vascular disease)
Swollen arteries (aneurysms)
Narrowing of the arteries, such as may occur in the neck (carotid artery stenosis).
Note: Doppler ultrasound is an important tool for detecting blockage of blood vessels or reducing the speed of blood flow in the vessels.
As you know, slowing down blood flow and blocking blood vessels can lead to a stroke or blood clots in the leg veins (deep vein thrombosis) or blockage of blood vessels in the lung area, causing a problem called pulmonary embolism.
Note: Doppler ultrasound may also be performed to check fetal blood flow. For this reason, this ultrasound is also performed in pregnant mothers.
The radiologist must be very skilled to both take the Doppler ultrasound test from the patient and interpret the results in the best possible way within a limited period of time.
How is Doppler ultrasound performed?
The Doppler sonographer places the device, which is the size of a bar of soap, on a specific area of the body (the area on which the Doppler ultrasound is to be performed).
This is done without any invasive procedure or entering through the skin. Therefore, the important advantage of this method is its safety.
After placing this device on the skin of the body, the specialist moves it.
The movement of blood cells in the person’s veins changes the speed of the return of the waves, and based on the return of the ultrasound waves, the processing device creates images on the monitor that show the blood flow in the person.
This test can be an alternative method for invasive methods such as angiography and venography.
During these two mentioned methods, a dye is injected into the blood vessels to obtain X-ray images, and according to these images, the person’s problem is diagnosed.
