Color duplex Doppler ultrasonography of the extracranial cervicocerebral vessels

We remind you that independent interpretation of the results is unacceptable, the information provided below is for reference purposes only.

Color duplex Doppler examination of the extracranial cervical and cerebral vessels is a modern ultrasound diagnostic method used to evaluate the condition of the carotid, vertebral, and other major neck vessels supplying blood to the brain.

The examination combines B-mode ultrasound imaging with color Doppler mapping, allowing simultaneous assessment of vascular anatomy, vessel wall thickness, the presence of atherosclerotic plaques, the degree of stenosis, and the direction and velocity of blood flow.

The method is used for diagnosing vascular diseases, assessing the risk of stroke, and monitoring treatment effectiveness.

Indications

• dizziness and headaches;
• tinnitus;
• episodes of loss of consciousness;
• memory, attention, or coordination disorders;
• transient ischemic attacks;
• suspected vascular atherosclerosis;
• arterial hypertension;
• diabetes mellitus;
• elevated cholesterol levels;
• smoking and other cardiovascular risk factors;
• follow-up after vascular surgery or interventions;
• preventive examination for patients over 40 years of age or as recommended by a physician.

Examination Method

The examination is performed using color duplex ultrasound scanning with Doppler technology.

During the examination, the physician evaluates vessel patency, intima-media complex thickness, the presence of atherosclerotic changes, thrombi, vascular deformities, as well as blood flow characteristics.

Procedure / Duration

The examination is performed with the patient lying on their back. A special ultrasound gel is applied to the neck, after which the physician systematically examines the vessels using an ultrasound transducer.

The procedure is painless, non-invasive, and does not involve exposure to ionizing radiation.

The average examination time is 20–30 minutes.

Limitations

The method has no absolute contraindications.

Image quality may be limited by pronounced anatomical features of the neck, bulky dressings, or open wounds in the examination area.

Advantages

• detailed assessment of the neck vessels;
• early detection of atherosclerotic changes;
• evaluation of the degree of vascular stenosis;
• real-time assessment of blood flow direction and velocity;
• safe procedure with no radiation exposure;
• painless and non-invasive;
• suitable for follow-up examinations and monitoring treatment effectiveness.

It is crucial to remember that the information provided in this section is not intended for self-diagnosis or self-treatment. If you experience any symptoms or a worsening condition, it is essential to consult a qualified medical professional for proper diagnostic testing and treatment recommendations. Only a qualified specialist can make an accurate diagnosis and determine the appropriate course of treatment. To ensure the most accurate and consistent evaluation of test results, it is recommended to have them performed at the same laboratory, as different laboratories may use varying methods and units of measurement for similar tests.
