Brain imaging and cerebrospinal fluid analysis are commonly used to diagnose brain aneurysms.
Computed Tomography (CT)CT scan is a fast and painless test to detect blood in the brain (subarachnoid haemorrhage). This is often the first test to detect a rupture.
Computed Tomography Angiography (CTA)CTA is a non-invasive test where a contrast dye is injected into the vein while a CT scan is carried out to produce detailed images of blood flow in the brain arteries.
Cerebral AngiographyCerebral angiography is an invasive test that produces pictures of the blood vessels in the head and neck.
Cerebrospinal Fluid AnalysisBrain fluid is retrieved from the spine using a needle. The fluid is tested for presence of blood. This may be ordered if a ruptured brain aneurysm is suspected despite a normal CT scan.
