A MRI without contrast is one tool a doctor can use to determine whether an aneurysm is present or has ruptured.
Brain aneurysms may also be identified with other medical imagery, such as:
While healthcare professionals can use both MRIs and CT scans to detect brain aneurysms, they frequently use MRIs to search for unruptured aneurysms in the brain.
They often use CT scans with contrast to look for signs of a bleeding or ruptured aneurysm.
When considering whether to request an MRI or a CT scan, doctors will consider a variety of factors, including possible allergies to contrast agents or the presence of metal in the body, which would make
Some smaller brain aneurysms may need only monitoring to ensure that they safely resolve and do not become bigger. Larger brain aneurysms or those in people with risk factors for a rupture may require:
- Microvascular clipping: surgical insertion of a clip to cut off blood flow to the aneurysm
- Platinum coil embolization: use of platinum wire in the artery to reduce blood flow to the aneurysm
- Stents: flexible mesh tubes that can be inserted to divert blood flow away from the aneurysm
In addition to surgical procedures, people with brain aneurysms may need medications to reduce the risk of stroke and seizures. Physical, occupational, or speech therapy may also be recommended to address any abilities the aneurysm has affected.
Factors that can affect the outlook for a person with a brain aneurysm include:
- hypertension or other health issues
- the size and location of the aneurysm
- the presence of any hemorrhaging or brain damage
Brain aneurysms can be easily overlooked since people may not experience symptoms before they rupture. While many brain aneurysms resolve without treatment, the survival rate is low if an aneurysm ruptures.
Medical imaging scans such as MRIs are important tools for detecting and monitoring brain aneurysms. If you experience symptoms of a brain aneurysm, it’s important to consult a healthcare professional as quickly as possible.
