Many brain aneurysms are silent and go unnoticed until it’s too late. Screening allows us to detect these early, before they cause serious complications. With today’s advanced imaging, we can assess risk, guide treatment, and offer reassurance to patients who may not even know they’re at risk.
What is a Brain Aneurysm Screening?
When it comes to brain health, early detection can make all the difference. A brain aneurysm - an abnormal bulge in a blood vessel in the brainoften develops silently. But with timely screening, especially for individuals at higher risk, it’s possible to detect aneurysms before they cause serious harm.
If you’re wondering what brain aneurysm screening involves, this guide will walk you through what to expect when you visit a specialized brain aneurysm clinic in Singapore. This article is part of our guide to brain aneurysm imaging, screening, and diagnosis. For a complete overview, visit our Brain Aneurysm MRI and CT Scans guide.
Common Questions About Brain Aneurysm Screening
Who should consider brain aneurysm screening?
Brain aneurysm screening is generally recommended for selected individuals rather than the general population. You may benefit from discussing screening with a specialist if you have a family history of brain aneurysms, certain inherited conditions such as polycystic kidney disease (PKD), or other recognised risk factors.
What happens during a brain aneurysm screening appointment?
Your consultation usually begins with a review of your medical history, family history and symptoms. If screening is appropriate, your specialist will recommend the most suitable imaging test, explain what to expect, discuss the benefits and limitations of screening, and answer any questions before proceeding.
Which scan is used to screen for a brain aneurysm?
Depending on your individual circumstances, screening may involve magnetic resonance angiography (MRA), CT angiography (CTA) or MRI. If more detailed evaluation is required, cerebral angiography may be recommended. Your specialist will choose the most appropriate imaging method based on your clinical situation.
How long does brain aneurysm screening take?
The consultation and imaging process varies depending on the type of scan performed. Most non-invasive imaging studies such as MRA or CTA are completed on the same day, while results and follow-up recommendations are discussed once the images have been reviewed.
What happens if a brain aneurysm is found during screening?
Finding a brain aneurysm does not automatically mean treatment is required. Many unruptured aneurysms can be monitored safely with regular follow-up imaging. If treatment is recommended, your specialist will explain all suitable options, including minimally invasive endovascular procedures and, where appropriate, microsurgical clipping.
Who Should Consider Brain Aneurysm Screening?
Brain aneurysms can happen to anyone, but certain factors may increase your risk. You may benefit from screening if you:
- Have a family history of brain aneurysms or stroke
- Experience persistent headaches, vision changes, or neurological symptoms
- Have conditions like high blood pressure, smoking history, or connective tissue disorders
- Discovered an incidental aneurysm or blood vessel abnormality in a previous scan
If any of these apply to you, a screening can offer peace of mind - or early intervention.
Step 1: The Initial Consultation
Your screening begins with a detailed consultation. A brain aneurysm specialist will:
- Review your medical history and family background
- Discuss any symptoms you’re currently experiencing
- Assess lifestyle factors that may contribute to your risk
- Answer any questions or concerns you have
This discussion helps your doctor determine whether imaging is necessary and which test is most appropriate for your case.
Step 2: Undergoing Imaging Tests
If screening is recommended, you’ll undergo one or more imaging tests to examine the blood vessels in your brain. Here are the most common options:
CT Scan (CT)
The CT scan uses X-rays and contrast dye to create detailed images of your brain’s blood vessels.
What to expect: You’ll lie still on a table while the scanner rotates around your head. The process is painless and takes about 15–30 minutes.
Magnetic Resonance Imaging (MRI)
Magnetic Resonance Imaging (MRI) is a non-invasive test that uses strong magnetic fields and radio waves to create detailed images of the brain’s internal structures.
What to expect: You’ll lie inside an MRI machine. The test may take 30–60 minutes, and it’s important to stay still for accurate images.
Magnetic Resonance Angiogram (MRA)
Magnetic Resonance Angiography (MRA) is a specialized imaging technique that focuses on visualizing blood vessels. It provides detailed images of the vascular system and is particularly useful for detecting vascular abnormalities.
What to expect: It uses the same MRI machine and procedure. The test may take 30–60 minutes, sometimes contrast agents are used, but not always. If screening is recommended, these are the most common options.
Usually, MRI/MRA is adequate screening for most individuals. There are several advantages including no radiation, no contrast, and it is very safe and effective.
Cerebral Angiography
Considered the gold standard, cerebral angiography is used when detailed vascular imaging is required.
What to expect: A thin catheter is inserted (usually in the groin or wrist) to inject contrast dye into your brain's arteries. It’s done under local anaesthesia and may involve short observation afterward.
Your doctor will recommend the best imaging option based on your health, symptoms, and scan availability.
Step 3: Preparing for Your Screening
Screening is generally straightforward, but here are a few things to keep in mind:
- Fasting may be required for certain scans involving contrast dye
- Wear comfortable, metal-free clothing, especially for MRI scans
- Bring a list of your medications and medical history
- Most procedures are done without sedation and do not require hospital admission
- Your clinic will provide clear instructions tailored to the test you’ll be undergoing.
Step 4: After the Screening - Understanding Your Results
Once your scan is complete, your doctor will review the images and share the results with you - usually within a few days. Outcomes may include:
- No aneurysm detected: Great news, but ongoing monitoring may be recommended if you're at high risk
- Small, unruptured aneurysm: Your doctor may recommend routine observation and lifestyle changes
- Larger or high-risk aneurysm: Your care provider will discuss treatment options such as endovascular coiling or surgical clipping
At our clinic, Dr. Manish Taneja believes in compassion and clear communication. Your results will be explained in detail, and you’ll receive guidance on next steps. After a brain aneurysm is identified, many patients begin exploring their journey on what treatment, monitoring, recovery, and long-term follow-up may involve.

When to Consider a Vascular Specialist Assessment in Singapore
Brain aneurysm screening is most valuable when tailored to an individual's personal risk factors. A specialist assessment helps determine whether screening is appropriate and which imaging test is most suitable.
Consider seeking a specialist assessment if you:
- Have a family history of brain aneurysms or aneurysmal subarachnoid haemorrhage
- Have been diagnosed with polycystic kidney disease (PKD), vascular Ehlers-Danlos syndrome (vEDS) or another inherited vascular condition
- Have persistent headaches, unexplained neurological symptoms or abnormal brain imaging
- Have previously been diagnosed with an unruptured brain aneurysm and require ongoing surveillance
- Have concerns about your individual risk and would like advice on whether screening is appropriate
- Would like a second opinion regarding brain aneurysm screening, imaging findings or treatment recommendations
A specialist consultation includes reviewing your medical history, family history, symptoms and previous imaging before developing an individualised plan for screening, monitoring or treatment.
Seek emergency medical attention immediately if you experience a sudden severe headache, weakness, difficulty speaking, seizures, loss of consciousness or sudden vision changes. These symptoms may indicate a ruptured brain aneurysm, stroke or another neurological emergency requiring immediate treatment.

Put Brain Aneurysm on Your Health Radar
Did you experience the worst headache of your life? Thoughts could be racing through your mind. A brain aneurysm is a weak spot in a blood vessel in the brain that can change over time. The key concern is when an aneurysm ruptures, which can disrupt blood flow, affect brain tissue, and lead to serious brain damage. Controllable conditions like high blood pressure can increase this risk and treatment options can depend on the condition. Surgical clipping is one option that prevents blood from entering the weakened area. In many cases, minimally invasive treatments can also be used to restore normal blood flow and reduce risk. We have created structured guides to help you explore each stage in more detail:
A simple (computed tomography) CT scan could be just what the doctor ordered and the first step in early detection and prevention of a brain aneurysm. Come in for an easy consultation with our brain aneurysm specialist in Singapore to be on your health radar.
