Doppler ultrasound
"They are fast, reliable tests and do not involve risks for the patient".
DR. ALBERTO BENITO BOÍLLOS CODIRECTOR. RADIOLOGY SERVICE
What is a doppler ultrasound?
Doppler ultrasound is a technique that combines the use of ultrasound and doppler.
It allows the evaluation of blood flow in the veins.
With this, it is possible to quantify the speed of flow, the diameter of the vessel, detect the presence of atheroma plaques, inflammatory lesions, stenosis, obstructions, etc.
This test makes it possible to observe the vascular structures and study the blood flow at a specific point.
It provides a large amount of hemodynamic and morphological data of the venous system.
When is the eco-doppler indicated?
The echo-Doppler is a non-invasive technique where the transducer is placed on the skin of the area to be explored and through the echo-Doppler images of structure, flow rate and indirectly, the volume circulating in a given vessel are obtained.
The venous ecodoppler is the most accurate diagnostic test for the diagnosis of venous pathology.
Moreover, it is indicated for the control of the evolution of the lesions that can appear in the carotid arteries.
Diseases in which an echo-Doppler ultrasound is requested:
Do you have any of these diseases?
It may be necessary to perform an echo doppler
How is Doppler Echo performed?
Realization of the eco-doppler
Ultrasonography of supra-aortic trunks is performed with the patient lying down, placing the transducer on the neck in different positions until the carotid and vertebral arteries are identified. The examination is completed with the study of blood flow in the orbital circuit (ophthalmic artery).
The transcranial Doppler is also performed with the patient lying down, placing the Doppler probe in the skull over the so-called acoustic windows (transtemporal, occipital, ophthalmic and submandibular windows), through which the ultrasounds can penetrate.
In this way, it is possible to identify the main intracranial arteries depending mainly on the acoustic window used and the depth of insulation.
Occasionally Doppler signal enhancers are used, which are administered intravenously and have no significant side effects. Both techniques can be performed on any person because, like any ultrasound, they are free of radiation risks.
Possible risks of the eco-doppler
It is not a painful test and does not produce any side effects.
You will be able to live a normal life and incorporate into your daily work or home tasks.
Limitations of echo-doppler
Despite its benefits, Doppler echocardiography has certain limitations:
- Operator dependence: The quality of the images and the interpretation of the results depend on the experience of the technician or doctor.
- Difficulties in obese patients: Ultrasound attenuation by fatty tissue can limit the quality of the images.
- Limitations in deep vessels: Vessels located in areas that are difficult to access may not be adequately visualized.
Where do we do it?
