In the advanced diagnostic centre of Molecular Diagnostics and Therapy at Radiology and Diagnostic Imaging, avail the diagnostic services of CT Neck Angiography, an NABL & NABH-approved diagnostic centre. CT Neck Angiography is a contrast-enhanced computed tomography (CT) imaging technique used to image blood vessels in the neck area, with particular emphasis on the blood vessels of the carotids and vertebrae. Helps doctors evaluate narrowing, obstruction, aneurysms, and damage and injury to vessels around and to the brain.

About CT Neck Angiography

CT Neck Angiography (CNA) is an imaging test that looks at blood vessels that supply the head and neck. This 3D CT image and the use of a contrast agent in the blood vessels improve the clarity of the blood vessels and allow detailed information about their structure and course to be given. Diagnosis may be recommended if the doctor thinks there is a disease process going on in the carotid artery, that the blood flow is inadequate, that the artery has been damaged, or that there is an aneurysm or an issue involving the flow in an artery in the neck. It can additionally help selected stroke assessments and experts in planning a vascular procedure or surgery.

What is CT Neck Angiography?

Angiography is a procedure that allows the examination of the blood vessels. CT Neck Angiography involves a special dye with iodine being placed into a vein in the body during a convenient time of the CT scan and then imaging the blood vessels located in the neck. The scan will show the carotid arteries, parts of the vertebral arteries, and more. The images help the radiologist to assess the constrictions, occlusion, dilation, damage, and anatomical variations of the blood vessels. The precise level of coverage varies based on clinical indication and is dependent on the protocol based on the referring physician's decision.

Common Reasons for CT Neck Angiography

• Evaluation of narrowing in the carotid artery: May be needed to check if it is narrowing and impacting blood flow to the brain.
• Evaluation of stroke or TIA: May help to identify a vascular defect, the presence of which can cause a decrease in vascular supply.
• Suspected aneurysm: CT Neck Angiography may help identify an abnormal arterial dilatation when clinically indicated.
• Neck trauma suspected of arterial trauma: evaluates for arterial trauma following trauma or significant trauma.
• Arterial dissection: CT angiography may help identify a tear in the arterial wall and assess its extent.
• Abnormal blood flow: Investigates abnormal blood flow (vasculature) of the brain and/or neck if a specific problem is suspected.
• Pre-operative assessment: Gives a detailed vascular anatomy prior to selected surgical or endovascular procedures.
• Selected conditions of known arterial abnormality: May be recommended for routine follow-up after diagnosis and/or treatment of selected arterial conditions.
• Congenital vascular variations: Aids in detection of some defects in the course and/or structure of arteries in the neck.

Conditions Evaluated

Arterial Dissection

An arterial dissection occurs when one of the layers in the wall of an artery tears. Where clinical dissection is suspected, CT angiography may help identify features suggestive of dissection and assess the extent of dissection.

Aneurysms

As part of the scans, CT Neck Angiography could be helpful in detecting enlarged arteries if that is the case. The images are detailed, which may provide the health practitioner with further information about the site of an aneurysm, size of the aneurysm, and the treatment of the condition.

Traumatic Vascular Injury

CT angiography will be used to assess the integrity of the carotid and/or vertebral arteries and to assess selected vascular complications following severe neck trauma.

Vascular Anatomical Variations

The examination is well detailed with facts related to the course, branching pattern, and configuration of the arteries of the neck. This can be beneficial information prior to some surgical or endovascular interventions.

Pre- and Post-Treatment Assessment

CT Neck Angiography might also be ordered to help choose which vascular abnormalities to treat or in follow-up to check treated vessels, as directed by the treating specialist.
