Can an MRI detect a brain aneurysm?

Magnetic resonance angiography (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.

Can MRI Miss brain aneurysm?

Aneurysm visible on MRI scan missed

Sadly there are cases in which medical practitioners have assessed the images of an MRI scan, yet have failed to identify an aneurysm, and thus failed to follow-up and treat the patient.

Most unruptured aneurysms are discovered incidentally during routine imaging of the brain, such as an MRI or CT scan (see Diagnosis of a Brain Aneurysm).

Do aneurysms show up on MRI without contrast?

MR does not involve radiation or contrast risks, while a CT produces better resolution and is better for operative planning. Patients suspected of having a ruptured aneurysm typically undergo a CT scan of the head and a CT angiogram, which shows subarachnoid hermorrhage and the aneurysm.

Angiogram: For a traditional angiogram, doctors insert a catheter (a thin tube) into your body to see your blood vessels more clearly.
