To assess and diagnose a possible brain aneurysm in Singapore, Dr. Manish Taneja conducts a CT scan (computed tomography) or an MRI (magnetic resonance imaging) to obtain detailed images of your brain's blood vessels and structures.

What to Know About a Brain Aneurysm Diagnosis

The diagnosis of a brain aneurysm is something that is highly concerning and should be treated immediately. Dr. Manish Taneja, our neurointervention specialist decribes it the following way.

Brain aneurysms are like ticking time bombs in our head. With them being out of sight, many may think that they could live with them. It is wise to know everything that you possibly can about brain aneurysms in case you are ever faced with this medical situation.

The Ultimate Guide to Brain Aneurysm post can help you learn about the causes, symptoms, and treatments for this potentially life-threatening condition. Brain imaging is one part of how aneurysms are detected and evaluated. To understand what leads to testing in the first place, you might also be interested to explore our guide to brain aneurysm causes and risk factors.

What Are the Causes of a Brain Aneurysm?

Although the exact causes of a brain aneurysm aren’t always clear, several factors can contribute to the ballooning caused by the weakening of blood vessel walls. These include:

• high blood pressure, or hypertension
• a family history of brain aneurysms
• the age and gender of the patient
• smoking and drug abuse
• atherosclerosis, plaque buildup in the arteries
• in rare cases, head injury or infection of the blood vessel walls

Who Should Be Diagnosed for Brain Aneurysm?

CT scans, MRI, MRA, and cerebral angiography may help identify aneurysms and evaluate signs of bleeding or rupture as well as other neurological changes associated with seizures. There are multiple medical tests that a doctor can perform to diagnose a patient with a brain aneurysm. A few of these tests include the following:

• MRI - This stands for magnetic resonance imaging using a magnetic field and radio waves to generate detailed images.
• MRA - This stands for magnetic resonance angiogram and is a type of MRI scan that is used specifically for blood vessels.
• CTA - This is a special type of CT scan that aims specifically at scanning blood vessels.
• Angiogram - This is yet another tool available to doctors who want to take a closer look at the patient's blood vessels to see if there is any bleeding or any kind of obstruction that needs to be treated immediately.

A doctor that detects something wrong with the blood vessels of his or her patient might diagnosis them with having had a brain aneurysm.

Brain Aneurysm MRI and CT Scans: What You Need to Know

Brain imaging plays a central role in detecting and evaluating brain aneurysms. Many patients are unsure what the different scans mean, when they are used, or what happens after results are found. Because brain aneurysms do not always produce clear symptoms, imaging tests such as CT scans or MRI are often important for diagnosis and evaluation. Visit, Would I Know if I Had a Brain Aneurysm?, to explore why brain aneurysm symptoms can feel uncertain and how doctors evaluate possible concerns.

MRI and CT scans provide important information about the brain and blood vessels. In some situations, more detailed imaging may also be needed to better understand the condition. This guide explains how brain aneurysm imaging works, when scans are recommended, and how results are used to guide next steps, so you can move forward with greater clarity and confidence.

When Imaging Is Used

Brain imaging may be performed in both emergency and non-emergency situations. In urgent cases such as sudden, severe headache or neurological symptoms, rapid imaging helps detect bleeding or other complications. Imaging studies may sometimes be recommended when headaches are associated with neurological symptoms or suspected vascular abnormalities. In non-emergency settings, scans may be used to screen individuals at higher risk or to investigate ongoing symptoms. Advanced imaging techniques also help evaluate cerebrovascular abnormalities and conditions affecting the brain’s blood vessels.

Understanding Your Scan Results

Once imaging is completed, the findings help guide next steps. This may include identifying whether an aneurysm is present, evaluating its size and shape, and assessing whether it requires monitoring or treatment. Not all aneurysms carry the same level of risk, and results are interpreted in the context of your overall health.

The Role of Imaging Over Time

Imaging is not only used to detect brain aneurysms, it also plays an important role in monitoring them over time. Follow-up scans may be recommended to track changes in size or structure and to ensure that any potential risks are identified early. Imaging also plays an important role after treatment, where scans are used to monitor aneurysm stability and treatment outcomes over time.

What Happens After Imaging

After imaging is completed, the next step is often a discussion with a specialist. This helps clarify what the findings mean, whether further tests are needed, and what options, if any, should be considered. Being prepared for this conversation can make it easier to understand your situation and make informed decisions.

After a brain aneurysm is identified, many patients begin exploring their journey on what treatment, monitoring, recovery, and long-term follow-up may involve.

What to Expect During Your First Scan

For many people, undergoing a brain scan for the first time can feel unfamiliar. Understanding what happens during the process, how long it takes, what you may experience, and how results are communicated, can help reduce uncertainty and make the experience more manageable.

When Should You Go For a Brain Scan?

Don't worry if you feel like you are somehow pressing the panic button by asking a doctor for a brain scan if you feel that something is wrong with your body. Popular culture has encouraged some people to think that a brain scan is an extreme medical intervention that should only be done in extreme cases, but that is simply not the case. The reality is that you can and should ask for a brain scan from your doctor if you fear that you might be suffering from a brain aneurysm or that you might be at risk for one.

The brain scan can help identify any blockages or other issues within one's blood vessels to help identify where the problems might exist and allow doctors to take the time to suggest correction treatments for those issues. 

Not all patients require screening, this depends on your risk profile. We provide brain aneurysm detection and care at our specialized brain aneurysm clinic at Supreme Vascular and Interventional Clinic in Singapore.

The Main Types of Brain Aneurysm Scans

Brain aneurysm CT Scan

In the arsenal of tools that doctors have to treat patients are CT scans. They are a useful tool for helping to diagnose and treat patients. Computed Tomography, commonly known as a CT scan, is one of the most important medical breakthroughs in modern medicine. Before CT technology existed, doctors had no reliable way to look inside the brain without invasive surgery. Brain conditions such as tumors, bleeding, or aneurysms could only be suspected based on symptoms - often after severe damage had already occurred.

That changed in the early 1970s when British engineer Sir Godfrey Hounsfield developed the first CT scanner. His invention combined X-ray technology with computer processing to create cross-sectional images of the body. Instead of seeing a flat shadow like a traditional X-ray, doctors could now see thin “slices” of the brain, allowing them to identify bleeding, swelling, and abnormal structures with unprecedented accuracy. This breakthrough was so significant that it earned a Nobel Prize in Medicine.

Within a few years, CT scanners became standard in major hospitals around the world. They quickly proved especially valuable in neurology and emergency medicine, where time is critical and the brain is extremely sensitive to injury.

What does the CT scan show you?

The American Cancer Society explains that a CT scan shows the bones, organs, and soft tissues of the body more clearly than a standard x-ray. This allows the trained eye of a doctor to identify where a potential issue might exist within their patient.

Brain aneurysms are dangerous not because they exist, but because they can rupture without warning, releasing blood into the space around the brain. When this happens, every minute matters.

What is the benefit of a CT scan?

The biggest benefit of a CT scan is that it offers more detailed information than x-rays or other medical interventions when it comes to the diagnosis and treatment of patients such as brain aneurysm.

CT scans became the preferred first test for suspected aneurysm rupture because they are extremely fast. A modern CT scan of the brain takes only seconds to a few minutes. They are excellent at detecting blood, they show up very clearly on CT images. When an aneurysm ruptures, blood spreads into the cerebrospinal fluid spaces and around the brain tissue. CT scans are widely available and patients scan be scanned immediately even in the middle of the night.

Cerebral Angiography and Advanced Imaging

In some cases, more detailed imaging may be required to better understand the types of brain aneurysm. For example, because blister aneurysms can be very small and difficult to detect, advanced neurovascular imaging and specialist interpretation are often important for accurate diagnosis and may be needed. Cerebral angiography provides highly detailed images of blood vessels and is often used when further evaluation or treatment planning is needed.

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.
