Brain Arterial Angio MRI

What is Brain Arterial Angio MRI? What is it Used For?

Brain arterial angio MRI (MR Angiography) is an advanced magnetic resonance imaging method that provides detailed and non-invasive imaging of the arteries that feed the brain. This method, which is more comfortable and safer than classical angiography, offers the possibility to evaluate the vascular structure without using radiation. It is of great importance for the early diagnosis and accurate treatment planning of brain vascular diseases.

When is Brain Arterial Angio MRI Performed?

Brain arterial MR angiography is frequently requested in cases such as sudden and severe headache, dizziness, vision loss, fainting, suspected stroke, and transient ischemic attack (TIA). It is also widely used in the diagnosis of stenosis, occlusion, aneurysm, arteriovenous malformation (AVM), and congenital vascular anomalies in the brain vessels.

Contrast-Enhanced and Non-Contrast Brain MR Angiography

Brain arterial angio MRI can often be performed without contrast material. However, contrast-enhanced MR angiography is preferred in cases where vascular structures need to be evaluated in more detail. Contrast material allows especially small vascular lesions and flow disorders to be seen more clearly.

Is Brain Arterial Angio MRI Safe?

Brain arterial MR angiography is a safe imaging method as it does not contain radiation. The procedure is painless and usually completed within 15–30 minutes. Remaining still during the scan is important for image quality.

Advantages of Brain Arterial Angio MRI

• Safe imaging without radiation
• Detailed examination of vascular structures
• Early diagnosis and rapid intervention
• Guidance for surgical and interventional procedures
• Evaluation of follow-up and treatment effectiveness

Conclusion

Brain arterial angio MRI is one of the most important imaging methods of modern medicine in the diagnosis and follow-up of brain vascular diseases. It is of great importance to have it done on time with the recommendation of a physician for early diagnosis, correct treatment, and prevention of permanent damage.

Preparation Before Brain Arterial Angio MRI

Usually, no special preparation is required before brain arterial angio MRI. However, if a contrast-enhanced examination is planned, blood tests showing kidney functions may be requested. Metal jewelry, watches, glasses, and electronic devices should be removed before the scan. Patients with pacemakers, brain stimulators, metal implants, or clips must inform the healthcare team. Relaxing measures can be taken under the control of a physician for patients with claustrophobia.

What Diseases Does Brain Arterial Angio MRI Show?

This examination provides high accuracy in the evaluation of brain vascular stenosis, occlusions, aneurysms, AVMs, vascular tangle formations, and vascular wall diseases. In addition, the condition of vascular structures after stroke and the response to treatment can be safely monitored with MR angiography.

How are Brain Arterial Angio MRI Results Evaluated?

The images obtained are reported in detail by a radiology specialist. The findings are evaluated together with clinical findings by neurology, brain surgery, or interventional radiology specialists, and a treatment plan is created.

General Evaluation

Brain arterial angio MRI is an indispensable diagnostic tool for the early diagnosis and correct treatment process of brain vascular diseases. Thanks to its safe, comfortable, and high diagnostic value, it is one of the cornerstones of modern neurological evaluations.
