Print this page. A brain aneurysm is usually diagnosed using a magnetic resonance imaging (MRI) scan and angiography (MRA), or a computerised tomography (CT) scan angiography (CTA).An MRI scan is usually used to look for aneurysms in the brain that haven't ruptured.This type of scan uses strong magnetic fields and radio waves to produce detailed images of your brain. CT scan is usually preferred if it's thought the aneurysm has ruptured and there's bleeding on the brain (subarachnoid haemorrhage). This type of scan takes a series of X-rays, which are then assembled by a computer into a detailed three-dimensional image.
