Doppler sonography, also known as duplex sonography, is an ultrasound examination. It is used to check veins and arteries. The examination is painless and safe.
Here you will find further information and selected doctors for Doppler sonography.
Doppler sonography belongs to the family of ultrasound examinations. Doppler sonography is used specifically to examine blood vessels, i.e. arteries and veins. It can check the direction of blood flow, for example. Doppler/duplex sonography can be used to detect constrictions in the vessels, such as the vessels in the neck.
If a vein or other vessel is constricted, the direction and speed of blood flow changes. This can be visualized in various ways and read by the doctor. Acoustic tones are just as possible as a color representation on the ultrasound image.
These methods can also
identify and determine deposits.
Doppler sonography is mainly used to examine veins and diagnose other vessels. For example, the aorta or carotid artery is examined more closely using this method.
Duplex sonography is therefore suitable for the reliable diagnosis and treatment of vascular diseases. As a result
can be tackled safely and painlessly. This method can even eliminate the need for more complicated imaging procedures such as computer tomography or magnetic resonance angiography.

Doppler sonography is also used during pregnancy. It is primarily used to check the blood flow velocity in the umbilical cord. The examination is not normally carried out before the 20th week of pregnancy. It may only be indicated earlier in justified individual cases.
Other areas of application: obstetrics and cardiology.
Doppler sonography is used in the following areas:
Duplex/Doppler sonography is a simple ultrasound examination. The doctor first applies a gel to the area to be examined. The gel helps the ultrasound probe to glide better on the skin. In addition, air between the transducer and the skin reflects the sound waves.
The doctor then moves the transducer over the area of skin in question. The internal structures in the body reflect the sound waves, which are then received by the transducer. The result is displayed on a monitor. The device can also emit sounds.
The doctor gets an impression of the vessels to be examined from the image and sound.
Not every doctor who carries out a normal ultrasound examination also offers Doppler sonography to their patients. Doppler sonography requires different equipment than a conventional ultrasound examination. These are not available in every doctor's surgery. If no suitable equipment is available, the doctor may refer the patient to a specialist.
If there is a medical indication, such as a suspected vasoconstriction, the statutory health insurance will cover the costs. However, if it is a preventive examination requested by the patient, it is a so-called individual health service (IGeL). The patient must then bear the costs themselves.
A Doppler/duplex sonography can cost several hundred euros .
Doppler sonography is a gentle method for examining blood vessels. This examination is painless for the patient and does not differ significantly from a normal ultrasound examination.
Nowadays, Doppler sonography can be carried out with almost all common ultrasound devices.
