Frequent headaches and dizziness can be a consequence of vascular pathologies of the brain. In order to identify them, there are various diagnostic and research methods, one of which is duplex scanning of the vessels of the neck and head.
This method is non-invasive and therefore considered safe. What is especially attractive is that it does not require any special training and has no contraindications.
Description of the study
Duplex examination of the great arteries is painless and safe for the patient. Before the scan, the doctor talks with the patient, studies his complaints, symptoms, and the results of other studies in order to have the most complete clinical picture.
MAG duplex scanning lasts from 15 to 30 minutes. The doctor applies a special gel to the required area of the skin, which promotes better transmission of the sound signal, after which the specialist begins to move the sensor and continuously monitor the image on the monitor on which the sections are reflected. After the examination, a conclusion about the scan results is immediately issued.
The mechanism of duplex scanning of the arteries of the head and neck is based on the principle of echolocation, in which the vessel is imaged in two planes (across and along). When performing a duplex study, the area in question is displayed in color. The doctor gets the opportunity to study the walls of blood vessels, surrounding tissues, lumen, speed and direction of blood movement.
Indications for use
The main factor that has a negative impact on the treatment of vascular diseases is untimely contact with a neurologist and late diagnosis of the disease. The circulatory system is closed in a cycle, so disruption of the blood supply to tissues in one area inevitably causes problems in another. Main indications for duplex scanning of the great arteries:
- problems with vision, coordination, understanding, or speech production;
- headache and frequent dizziness;
- fainting or attacks of impaired consciousness;
- unsteadiness of gait;
- numbness of the limbs.
Duplex scanning of the main arteries of the head is also carried out if any pathologies of the vascular system are detected during other studies. Diagnostics are necessary so that the neurologist can assess the effect of the disease on the brain and prescribe adequate treatment.
There are two types of duplex scanning: two-dimensional mode and Doppler effect. The two-dimensional mode is used for visualization of blood vessels. The doctor receives information about the direction and speed of blood flow using the Doppler mode. These studies are indicated in the presence of the following pathologies or symptoms:
- fainting;
- sharp and frequent headaches;
- a feeling of coldness in the extremities or their swelling, cyanosis;
- development of trophic ulcers;
- sudden changes in blood pressure;
- tinnitus;
- weakness in the legs when walking.
The Neurology Clinic of the Yusupov Hospital employs neurologists with extensive experience who treat patients even with serious illnesses that other specialists have refused. An individual approach, modern treatment methods, high-precision and effective equipment allow us to promptly identify problems and develop ways to eliminate them.

Methodology
No special preparation of the patient is required before the study. Taking medications should be carried out as usual, but you must inform your doctor about taking medications. Duplex scanning is performed in a comfortable and calm environment for both the patient and the staff. During duplex MAG, the main arteries of the head and neck are examined in the supine position.
Before scanning, the doctor applies an acoustic gel to the surface of the patient’s skin; it increases sound conductivity and makes it easier for the device to glide over the surface of the skin.
Then a special sensor is placed in place of the vessels being examined. When installing sensors, the doctor takes into account the location of the “ultrasonic windows” - areas of the skull with the thinnest bones or those with holes. Through these zones, the ultrasound beam easily enters the skull.
This diagnostic method does not cause discomfort in the patient. During the test, the doctor may ask the patient to take a certain position or hold his breath. The duration of the study does not exceed half an hour.
Experienced doctors include the main advantages of this method: the ability to obtain adequate characteristics, identify various vascular diseases in the early stages of development, the ability to detect the presence of a blood clot, and the low invasiveness of the method.
Do you need any preparation for the procedure?
Ultrasound duplex scanning does not require special preparation, the only exception is ultrasound scanning of the abdominal vessels (abdominal aorta).
Ultrasound scanning
of the abdominal aorta
requires additional preparation, including:
- fasting for 8 hours before the procedure;
- a three-day diet excluding raw vegetables, meat, milk and black bread, in addition, the patient is prescribed a drug to eliminate gas formation.
MAG research methods
Ultrasound of cerebral vessels can be performed in several modes, each of which allows one to obtain certain information. Often, a patient who has been referred by a neurologist for diagnostics does not fully understand the features of these techniques and the results obtained.
Doppler ultrasound of the main arteries of the head is performed using a sensor operating on the basis of the Doppler effect. In this study, the reflection of sound waves from moving objects is measured, the result is an image of the vessels in 2D mode, which shows problem areas. Doppler sonography is used to determine obstructions and blood flow parameters.
Duplex scanning of the main arteries of the head allows the doctor to obtain information about the anatomy of the vessels, their condition, direction and speed of blood flow. This method is highly informative; it allows you to identify even minor disorders before the appearance of serious symptoms. Triplex scanning of the main arteries of the head is a duplex scanning mode, when using which the doctor receives a color image. The scanning device operates in three modes.
The neurology clinic performs Doppler sonography of the main arteries of the head and other studies. The Yusupov Hospital is equipped with modern equipment, so the research results are as accurate as possible, which helps to successfully verify the diagnosis.
Decoding the results
As a rule, results can be obtained within a few minutes after ultrasound scanning. The result is a printout containing a list of examined vessels with a description, and the presence of anatomical anomalies is also reflected there.
The description of the condition of the artery includes the following indicators:
- nature of blood flow;
- the speed of blood movement along the artery – maximum (max) systolic (during contraction of the heart muscle) and minimum (min) diastolic (at the moment of relaxation):
- pulsatory index - calculated based on the maximum and minimum blood flow speed;
- resistive index - also calculated based on speed indicators;
- the ratio of speeds in systole and diastole - maximum divided by minimum;
- wall thickness, artery diameter.
Pulsator and resistive indices, as well as the max/min ratio are measured to assess arterial patency.
Normal values vary for different arteries.
As an example, the table shows the recommended indicators for some arterial lines:
| Index | Common carotid artery | External branch of the carotid artery | Internal branch of the carotid artery | Vertebral arteries |
| Diameter, mm | 4–7 | 3–6 | 3–6,5 | 2–4,5 |
| Speed in systole (max), cm/sec | 50–105 | 35–105 | 33–100 | 20–60 |
| Velocity in diastole (min), cm/sec | 9–36 | 6–25 | 9–35 | 5–25 |
| Resistive index | 0,6–0,9 | 0,5–0,9 | 0,5–0,9 | 0,5–0,8 |
Normally, the artery should not contain narrowings (0% stenosis), thickening or plaque, and blood should move freely without flow turbulence (eddies).
Common deviations from normal vascular characteristics include:
- stenosis - the lumen is narrowed, blood is not able to flow freely;
- aneurysm - local expansion of the vessel wall against the background of a weakening of its tone;
- atherosclerotic changes - the lumen of the vessel is narrowed due to the presence of cholesterol plaques. The conclusion describes the structure, size, degree of narrowing;
- turbulent blood flow - the presence of turbulence in the blood flow;
- disturbance of vascular tone in vegetative-vascular dystonia;
- vasculitis - a wall thickened over a long period or exfoliating.
Ultrasound scanning of veins contains fewer digital indicators; here it is assessed:
- anatomy and tortuosity;
- patency and quality of outflow;
- diameter and presence of obstacles in the lumen of the vein.

What is the scanning procedure like?
Regardless of which vessel is being examined, duplex scanning of vessels
The procedure follows approximately the same plan: the patient lies down in such a way that the area being examined is accessible to the sonologist. The doctor moves the scanner over the vessels of interest and reads the readings from the monitor.
Differences between duplex and triplex scanning
Duplex and triplex scanning of blood vessels are not interchangeable. With duplex scanning, you can view the lumen and wall of the vessel in a two-dimensional plane. While triplex scanning involves the use of three modes, including gray scale, as well as color and spectral Dopplerography.

The main indicators revealed during the MAG ultrasound procedure
Scanning helps identify:
- quantitative and qualitative characteristics of cholesterol deposits and blood clots;
- the degree of damage to the arteries, deformation of their shape;
- the quality and degree of thickening of the walls of blood vessels and their loss of plasticity;
- parameters of imbalance between vasoconstriction and vasodilation of the endothelium (motor function of arteries);
- damage and integrity of vascular walls;
- the presence of aneurysms and their parameters;
- the degree of disturbance and the size of the gaps in the walls of the arteries;
- any conditions that cause brain hypoxia due to circulatory disorders.
This procedure can also be prescribed to monitor the quality of medical therapy for disorders of the blood supply to the brain.
The most complete picture of the extent of pathologies can be given by color (triplex) scanning. In this case, with changes in blood flow and its speed characteristics, the colors of the image also change. Thus, color Doppler sonography provides the optimal number of changes and a better result regarding the state of blood circulation.
