How is a brain aneurysm detected?
To find out if you have a brain aneurysm, your healthcare provider will order an imaging test. These tests show the size, shape and location of brain aneurysms:
- MRI (magnetic resonance imaging).
- CT (computed tomography).
- Diagnostic cerebral angiogram
- MRA (magnetic resonance angiography).
- CTA (computed tomography angiography).
Occasionally, a ruptured aneurysm may not show on the initial imaging test. If your symptoms point to a ruptured aneurysm, your doctor may order a lumbar puncture (spinal tap). This test shows whether there’s blood in the fluid surrounding your brain.
