Description: Brain artery CT angiography is a modern diagnostic method that provides detailed images of the blood vessels in the brain. This highly informative technique is used to visualize the arteries supplying the brain and detect potential pathological changes such as stenoses, aneurysms, occlusions, or other disruptions in blood flow.
 
Key Arteries Visualized:
Carotid Arteries: Major arteries supplying blood to the front part of the brain.
Vertebral Arteries: Arteries supplying blood to the back part of the brain and cerebellum.
Basilar Artery: Formed by the fusion of the two vertebral arteries, supplying blood to the brainstem and cerebellum.
 
Indications for CT Angiography of the Brain Arteries:
Suspected brain artery aneurysms.
Evaluation of stenosis or occlusion of brain vessels in suspected ischemic stroke.
Planning of surgical interventions on brain vessels.
Monitoring of vessels post-surgery or endovascular procedures.
Diagnosis of congenital vascular anomalies.
Assessment of blood flow in cases of suspected vasculitis or other inflammatory vascular diseases.
 
Preparation for the Procedure:
Fasting: Fast for 6-8 hours before the exam. Small amounts of water are allowed.
Medication: Consult with your doctor about discontinuing any medications that may affect the results.
Allergies: Inform medical staff of any allergies to iodinated contrast agents or other substances used during the procedure.
Pregnancy: Notify your doctor if you are pregnant or suspect pregnancy, as the procedure may be postponed or modified.
Follow Instructions: Carefully follow all instructions and recommendations provided by the medical staff.
 
Procedure: Brain artery CT angiography is a non-invasive procedure where a contrast agent is injected intravenously. The CT scanner then performs a series of scans to visualize the brain's blood vessels and identify any potential issues.
