Description

Cerebral MRA is a non-invasive MRI-based scan to evaluate brain blood vessels for aneurysms, stenosis, or vascular malformations; patients in China can arrange hospital booking and interpreter support via ChinaMedicalHub for ¥1,000–¥2,000.

Main Uses

The primary purposes of a head MRA include: 1. Evaluating the blood vessels in the brain for stenosis, occlusion, or aneurysms, 2. Assessing patients with stroke or transient ischemic attack (TIA) to identify potential causes, 3. Screening for vascular abnormalities such as AVMs or aneurysms, 4. Monitoring the effectiveness of treatments for vascular diseases, 5. Planning for surgical or interventional procedures involving the cerebral vasculature

Normal Range

MRA (Magnetic Resonance Angiography) of the head does not have a specific numerical range for normal values as it is an imaging test. A normal MRA shows clear, unobstructed blood vessels with no signs of narrowing, blockages, or aneurysms. The cerebral arteries and veins should appear smooth and continuous without any irregularities.

Low Values - Possible Causes

Since MRA is an imaging technique, 'low' values do not apply in the traditional sense. However, findings that might be considered as indicating lower than expected flow or vessel size could include: 1. Vessel underdevelopment, 2. Post-surgical changes, 3. Congenital anomalies, 4. Chronic hypoperfusion conditions, 5. Technical issues during the scan

High Values - Possible Causes

Similarly, 'high' values are not applicable, but conditions that may cause abnormal enlargement or increased visibility of vessels on MRA can include: 1. Aneurysms, 2. Arteriovenous malformations (AVMs), 3. Vasculitis, 4. Tumors causing vascular compression or displacement, 5. Increased blood flow due to arteriovenous fistulas
