CT angiography of the vessels of the neck and head — is an X-ray examination with intravenous contrast enhancement, which allows detailed assessment of the condition of the vessels that provide blood supply to the brain. It helps detect narrowing, thromboses, aneurysms, and other disorders that may be the cause of headache, dizziness, or other neurological symptoms.
At the «Oxford Medical» medical center, CT angiography is performed on modern scanners GE Revolution Maxima and SIEMENS Healthineers SOMATOM go.Up. This allows obtaining clear layered images and 3D reconstructions of the vessels and accurately assessing their condition, localization of changes, and influence on the blood supply of the brain.
CT angiography of the vessels of the neck and brain can be done in Kyiv on the right bank — near the «Dorohozhychi» metro station, as well as on the left — at Berezniaky. Make an appointment at a time convenient for you by phone or request a callback on the website.
CT angiography of the vessels of the neck and brain covers arteries and veins that provide blood supply to the brain and pass through the neck area. During the examination, a series of images is performed, which allows assessing the course of the vessels, their diameter, patency, symmetry, and relationship with surrounding structures.
CT angiography allows assessing the following structures:
| Examination area | What is assessed |
| Arteries of the neck | Carotid and vertebral arteries, their lumen, patency, presence of narrowings, bends, atherosclerotic changes. |
| Arteries of the head | Intracranial arteries, areas of stenosis or occlusion, aneurysms, vascular malformations. |
| Venous system | Venous sinuses and veins, features of venous outflow, signs of thrombosis. |
Computed tomography of the vessels of the head and neck allows obtaining images in different planes and creating a 3D reconstruction of the vessels. This helps the doctor more accurately assess anatomical features and detect even minor changes that may have clinical significance.
CT angiography is prescribed when it is necessary to assess the vessels in detail and
find out whether the patient’s complaints are related to impaired blood supply to the brain.
Main indications:
neurological symptoms: sudden headache, dizziness, impaired coordination, weakness in the limbs, changes in speech or vision;
suspicion of vascular pathology: narrowing or blockage of vessels, aneurysms, vascular malformations;
monitoring of the condition of arteries and veins after previous circulatory disorders (stroke, transient ischemic attack);
preparation for treatment or clarification of the diagnosis based on the results of other examination methods.
CT angiography of the brain and neck may be recommended when there is suspicion that the symptoms are associated with narrowing of the carotid or vertebral arteries, impaired blood flow in the intracranial vessels, or the risk of acute cerebrovascular accident. In some cases, CT angiography complements CT of the brain, when it is important to additionally assess the vessels and blood supply of the brain.
Doctors of «Oxford Medical» recommend not postponing a consultation if headache is accompanied by weakness in the arm or leg, speech impairment, facial asymmetry, sudden deterioration of vision, or pronounced dizziness. In such cases, it is important to seek medical help as quickly as possible.
Separately, CT angiography may be appropriate for patients who have consequences of stroke. The examination helps assess the condition of arteries and veins, identify risk factors for repeated episodes, and determine further tactics of monitoring or treatment.
CT angiography of the vessels of the neck and head has certain limitations associated with the use of X-ray radiation and intravenous administration of a contrast agent.
Main contraindications:
Relative limitations:
The contrast agent is eliminated from the body mainly by the kidneys, therefore, in case of their diseases, the appropriateness of the examination is assessed individually. If necessary, the doctor may prescribe additional tests or suggest an alternative diagnostic method.
Preparation for CT angiography is minimal, but important for the safe performance of the examination with contrast enhancement.
Before the procedure, it is recommended:
If there are kidney diseases, diabetes mellitus, or reactions to contrast agents occurred previously, this must be reported to the doctor before the examination.
On the day of the procedure, it is worth coming without metal jewelry in the area of the head and neck or removing it immediately before the examination.
Before the examination begins, the patient is placed on the movable table of a computed tomography scanner. To obtain clear images, it is important to remain still, so the head is fixed in a comfortable position using special pads.
After preparation, the table smoothly moves into the scanning zone, and the examination begins. The procedure is painless and lasts several minutes.
Since CT angiography is performed with contrast enhancement, a catheter is placed into a vein before scanning. The contrast agent is injected automatically during the examination, which allows clear visualization of arteries and veins at the moment the agent passes through the bloodstream.
During the injection of contrast, a feeling of warmth in the body, a short-term metallic taste in the mouth, or a feeling of heat is possible — this is a normal reaction that quickly passes.
The total duration of the procedure together with preparation usually takes about 10–20 minutes. After the examination is completed, the radiologist analyzes the obtained images, assesses the condition of the vessels, their patency, the presence of narrowings, thrombi, aneurysms, or other changes. The conclusion indicates the nature of the detected changes or states that the indicators correspond to the norm. The results are given to the patient for further consultation with the doctor who referred them for the examination. Usually this is a neurosurgeon, vascular surgeon, or neurologist.

At the «Oxford Medical» medical center, CT angiography is performed on expert-class scanners GE Revolution Maxima and SIEMENS Healthineers SOMATOM go.Up. The equipment provides high image detail, which allows obtaining clear layered slices and 3D reconstructions of vessels for accurate assessment of their condition.
The examination can be undergone in Kyiv on the right bank — near the «Dorohozhychi» metro station, as well as on the left — at Berezniaky. You can make an appointment at any time convenient for you by phone or by requesting a callback on the website.

In Kyiv, CT of the cerebral vessels can be undergone at the «Oxford Medical» medical center. Diagnostics is performed on the right bank — near the «Dorohozhychi» metro station, as well as on the left bank — at Berezniaky. The clinics are equipped with modern scanners, which allows obtaining accurate results.
CT angiography of the vessels of the brain and neck itself takes only a few minutes, since scanning is performed quickly. Together with preparation, catheter placement, and administration of the contrast agent, the procedure usually takes about 10–20 minutes.
During CT angiography of the vessels of the brain and neck, it is possible to detect narrowing or blockage of vessels, aneurysms, thromboses, vascular malformations, disorders of venous outflow, as well as changes after a previous stroke or traumatic brain injury. The examination allows assessing the condition of arteries and veins, their patency, and features of blood flow, which is important for establishing an accurate diagnosis.
Approximately, the permissible additional radiation exposure is up to 1 mSv per year, while one examination gives about 2–5 mSv. This is a small dose that is considered safe in medicine. According to RadiologyInfo, CT can be performed as many times as needed for diagnosis and monitoring of the patient’s condition.
Modern equipment. CT angiography is performed on GE Revolution Maxima and SIEMENS SOMATOM go.Up.
Accurate images. The scanners create layered slices and 3D reconstructions of the arteries and veins of the head and neck.
Fast examination. Scanning takes several minutes, and preparation does not require complex steps.
