During this X-ray test, a catheter is inserted through a blood vessel in the groin or arm and moved up through the vessel into the brain. A dye is then injected into the cerebral artery. The dye allows any problems in the artery, including aneurysms, to be seen on the X-ray. Although this test is more invasive and carries more risk than Computed tomography angiogram (CTA) and Magnetic resonance angiography (MRA) scans, it is the best way to locate small (less than 5 mm) brain aneurysms.
