A member asked:

Would an mri of the orbits with contrast spot a cerebral aneurysm?

A doctor has provided 1 answer

Limited sensitivity: The answer to your question is "possibly." Better resolution comes from an intracranial MRA, which looks at all cerebral vessels. CTA (a CAT scan of the cerebral arteries with contrast) is also useful. The gold standard is still cerebral angiography (involving a catheter inserted into the vessels to deliver contrast while under x-ray fluoroscopy).
