Depends on the size: The best MRI study is an mra (angiogram) but even this misses aneurysms less than 3mm

Yes: It has to be an MRA, magnetic resonance angiogram, which looks at the blood vessels and not just the brain tissue, which would be a MRI. CTA can also be done but that involves ionizing radiation. Catheter cerebral angiography is invasive but provides the best information. For screening purposes, MRI/MRA would be the preferred test for brain aneurysms. Please refer to www.chicagoaneurysm.com
