What is CT Angiography Brain and Neck?

CT angiography brain and neck, or CTA, is a medical imaging procedure that utilises computed tomography (CT) technology. It produces detailed three-dimensional images of blood arteries in the brain and neck. 

CT angiography of head and neck anatomy assists in the diagnosis of various neurological and vascular problems. This may include aneurysms (abnormal bulge or swelling in a blood vessel) and stenosis (narrowing or constriction of a blood vessel or any tubular organ).

Need for CT Angiography of Brain and Neck

CT Angiography of the brain and neck is recommended for people who exhibit specific symptoms or conditions. It is also done as a preventive measure for certain high-risk groups. This procedure is typically recommended for:

For CT Angiography of the Head:

  1. Aneurysm: CTA can effectively detect intracranial aneurysms, which are abnormal bulges or weak areas in the blood vessels of the brain. 
  2. Stenosis: It is used to assess blood vessel narrowing or stenosis in the brain. This can impede blood flow and lead to neurological symptoms.
  3. Dissection: This procedure can reveal arterial dissections, where the inner lining of an artery tears and can result in blood flow abnormalities or stroke.
  4. Arteriovenous malformation (AVM): CTA can help identify arteriovenous malformations. These are abnormal tangles of blood vessels that can disrupt normal blood flow and increase the risk of bleeding.

For CT Angiography of the Neck:


  1. Carotid Stenosis: CTA is commonly used to assess carotid artery stenosis. It is the narrowing of the carotid arteries in the neck. Carotid stenosis can increase the risk of stroke, and CTA helps determine the degree of stenosis and the need for intervention.
  2. Dissection: Like in the head, CTA can also detect arterial dissections in the neck. This problem can lead to reduced blood flow and neurological symptoms.
  3. Tumour: This test may be used to evaluate blood flow and the extent of vascular involvement in neck tumours. This information can help guide treatment decisions and surgical planning.

Benefits of CT Angiography Brain and Neck

CT Angiography offers insights into the vascular health of vital regions like the brain and neck. Here are some key advantages:

  1. Non-invasive Imaging: It eliminates the need for invasive treatments such as standard angiography. Please note that there are no incisions required. 
  2. Rapid Results: Provides images that are both speedy and detailed. This allows for timely diagnosis and treatment planning.
  3. Highly Detailed Images: Offers useful blood vessel visualisation, assisting in diagnosing aneurysms or other vascular anomalies.
  4. 3D Reconstructions: Enables 3D visualisation of vascular structures, aiding surgical planning and intervention.

Preparation of CT Angiography Brain and Neck

CT Angiography (CTA) of the brain and neck typically takes 15 to 30 minutes. It is important to follow any specific instructions provided by the doctor. Here's a general overview of the preparation:

  1. Medication Review: Patients should inform the healthcare team about any medications they are currently taking.
  2. Medical History: They should provide an entire medical history, including any allergies and previous adverse reactions to contrast dye.
  3. Fasting: Depending on the specific instance, fasting for a few hours before the procedure may be recommended. This is especially needed if contrast dye has been used in the procedure.
  4. Consent for Contrast Dye: If required, patients should sign a consent form to use contrast dye and address any possible risks or allergies with the medical team.

CT Angiography Brain and Neck Procedure

As stated before, CT brain/neck angiography is a non-invasive technique that offers a rapid and accurate assessment of blood vessels. Here's an overview of the procedure:

  1. Contrast Dye Injection: A contrast dye is injected into a vein intravenously to improve the visibility of blood vessels in the resulting images.
  2. CT Scanner: The patient is placed on a CT scanner table. It moves through the scanner to obtain cross-sectional images.
  3. Image Reconstruction: The images are reconstructed using advanced software. This creates comprehensive 3D representations of the brain and neck vasculature.
  4. Radiologist's Interpretation: A radiologist evaluates the images, looking for aneurysms, stenosis, vascular anomalies, and other problems.

Aftercare of CT Angiography Brain and Neck

After undergoing a neck and brain angiography CT scan, there are generally no specific aftercare instructions. However, here are some general guidelines to consider:

  1. Stay Hydrated: Following the procedure, patients should drink plenty of fluids to help flush the contrast dye from their systems.
  2. Resume Normal Activities: Since there is no recuperation time necessary, one can normally resume regular activities soon after the scan.
  3. Follow Medication Advice: If the doctor has instructed to alter the medications temporarily, patients should do that as prescribed.
  4. Monitor for Allergic Reactions: Although allergic reactions are uncommon, one should call the doctor if they suffer symptoms like itching or difficulty breathing.

Results of CT Angiography Brain and Neck

Typically, the radiologist generates the CT angiography of brain and neck report within hours to a day. This allows for quick diagnosis and treatment planning. The result assesses several factors, including:

  1. Vascular Anatomy: The exam provides a thorough view of the vascular structures in the brain and neck. This includes the circle of Willis, carotid arteries, and vertebral arteries.
  2. Aneurysms: The procedure assesses for the presence, location, and size of any aneurysms (abnormal bulges in blood arteries).
  3. Stenosis: The degree of constriction or obstruction in blood arteries is measured in stenosis. Stenosis can reduce blood flow and may be an indication of atherosclerosis.
  4. Arteriovenous Malformations: The scan aids in detecting aberrant connections between arteries and veins, like arteriovenous malformations.
  5. Ischemia: CT Angiography can detect areas with decreased blood flow, which may suggest ischemic conditions such as stroke.
  6. Tumours: The test examines the presence and vascularity (blood supply) of brain tumours.
  7. Clots: Blood clots within the vessels are recognised, which is useful in detecting disorders such as deep vein thrombosis (DVT).

FAQs for Brain Neck CT Angiography

CT Angiography brain anatomy refers to the detailed imaging of the blood vessels within the brain. It uses computed tomography (CT) technology and provides a visual map of the vascular network within the brain.

The major blood vessels in the brain and neck that can be visualised using CTA are:

  1. Carotid arteries

  2. Vertebral arteries

  3. Circle of Willis

  4. Anterior cerebral arteries

The common variations in the branching patterns of the cerebral arteries are:

  1. Fenestration: Splitting of an artery into two smaller branches

  2. Aplasia or Hypoplasia: Absence or underdevelopment of certain arteries

  3. Accessory Arteries: Additional arteries that are not part of the typical cerebral circulation 

  4. Cross-communication: Abnormal connections between arteries 

  5. Aberrant Origins: Arteries that arise from different locations

These variations can complicate CTA interpretation. This can potentially lead to misdiagnosis or confusion.

The Circle of Willis is a circle of interconnected arteries at the base of the brain. It's important in CTA imaging of the brain because it ensures continuous blood supply, even if one of the arteries is blocked. It also helps assess blood flow patterns and potential abnormalities in the brain's vasculature.

Variations or anomalies in neck anatomy can impact the assessment of blood flow and the presence of stenosis (narrowing). It can also affect the location of potential vascular abnormalities in the carotid arteries.

The size of the major blood vessels in the brain and neck varies from one individual to another. For instance, in the internal carotid artery, the size can range from 4mm to 7mm. CT angiography (CTA) can detect abnormalities in size by providing detailed cross-sectional images of blood vessels.

The standard CTA protocol for imaging the brain and neck typically involves the intravenous injection of contrast dye. It is followed by cross-sectional imaging with a CT scanner. It often includes 3D reconstructions of the blood vessels.

CT Angiography differs from other imaging modalities as follows:

  1. Uses X-rays and involves radiation exposure, while MRI and conventional angiography do not

  2. Provides quick results, often faster than MRI

  3. Readily offers 3D reconstructions

  4. Less affected by metal implants than MRI

Contrast media is administered intravenously (IV) during a CTA scan. This process is crucial for a detailed evaluation of the blood vessels during a CTA scan.

Risks associated with contrast administration during medical imaging procedures like CTA include:

  1. Allergic reactions

  2. Kidney damage (contrast-induced nephropathy)

  3. Contrast extravasation

Here are the common artefacts in CTA images and their mitigation:

  1. Motion Artefacts: Minimised by patient immobilisation and breath-holding instructions.

  2. Beam Hardening: Corrected with post-processing algorithms and adjusting imaging parameters.

  3. Streak Artefacts: Addressed through software-based correction algorithms.

  4. Metallic Artefacts: Reducing metal in the field of view or using specialised imaging techniques.

A typical CTA scan of the brain and neck takes about 15 to 30 minutes. Factors that can affect scan time include:

  1. The complexity of the study

  2. Patient cooperation

  3. Need for additional scans or sequences

Guidelines for Patient Preparation:

  1. Fasting, if advised.

  2. Informing the doctor of allergies, kidney problems, or pregnancy.

  3. Removal of metal objects and jewellery.

Minimising Patient Motion:

  1. Informing patients about the importance of staying still during the scan.

  2. Using straps or foam pads to minimise patient movement.

  3. Instructing patients to hold their breath when needed.

CT angiography brain costs between ₹ 5,000 and ₹ 8,000 in India. The type of hospital or centre and several other factors determine the exact cost.

The CT Angiography costs are as follows:

  • For brain:  ₹ 5,000 and ₹ 8,000

  • For neck:  ₹ 5,000 to ₹ 7,500

Common findings on CTA images of the brain and neck and their associations with various disease states include:

  1. Aneurysms: Associated with the risk of rupture and hemorrhagic stroke

  2. Stenosis: Can lead to conditions like ischemic stroke or carotid artery disease

  3. Vascular Malformations: Can cause various neurological symptoms

  4. Tumours: Might affect blood flow, potentially linked to brain tumours

CTA is used to diagnose and monitor conditions by providing detailed images of blood vessels in the brain and neck. It can reveal the presence of aneurysms, arteriovenous malformations, and other vascular abnormalities.

Radiologists interpret CTA images of the brain and neck by examining key features such as:

  1. Blood Vessel Anatomy

  2. Blood Flow

  3. Aneurysms

  4. Stenosis

  5. Vascular Malformations

Limitations of CTA Imaging:

  1. Radiation Exposure

  2. Contrast Dye Allergies

  3. Kidney Function Impact

  4. Limited Soft Tissue Detail

Comparatively, MRI has no radiation exposure and excels in soft tissue imaging. Conventional angiography is more invasive and carries risks. However, it provides the highest-quality vascular imaging and therapeutic capabilities.

CTA is often combined with other imaging modalities, such as MRI and conventional angiography. This is done to provide a more comprehensive evaluation of the brain and neck vasculature. This multi-modal approach offers a well-rounded view of vascular anatomy and structural details.
