Brain Aneurysm

A ruptured brain aneurysm is a very serious conditions that in some cases can be fatal. A quick and accurate diagnosis is essential for your recovery. Tests commonly used in the diagnosis of aneurysms include:

  • Cerebral Angiography This test is commonly used to diagnose aneurysms. A special dye that can be seen on X-rays is injected into an artery that supplies blood to the brain. The dye flows through the brains blood vessels and can show any obstructions or leaks.
  • Magnetic Resonance Angiography (MRA) Using a strong magnetic field, an MRI can generate a 3-D image of the brain and a detailed image of blood vessels that can be used to detect, diagnose and aid the treatment of aneurysms. The procedure is painless.
  • Computed Tomography (CT) Scan With this test, X-ray beams create a 3-D image of the brain. A CT scan can detect bleeding in the artery after the aneurysm has burst.
