What Is a Carotid Intima-Media Thickness (CIMT) Test?
A carotid intima-media thickness (CIMT) test is a non-invasive
ultrasound scan that measures the thickness of
the inner two layers of the carotid artery wall in the neck.
This helps detect early signs of atherosclerosis, a condition where fatty
deposits called plaque build up inside the arteries, causing them to harden and narrow.
Atherosclerosis reduces blood flow and increases the risk of serious conditions such as
stroke and heart disease.
By assessing artery wall thickness and identifying plaque formation, the CIMT test provides an
estimate of how healthy your arteries are compared to what is expected for your age, and helps
evaluate your future risk of cardiovascular events.

When Is a CIMT Test Typically Recommended?
A CIMT test may be recommended for individuals with risk factors to detect early arterial changes that may not cause symptoms but signal a higher chance of cardiovascular disease. This includes those with:
- High blood pressure
- High cholesterol or triglycerides
- Type 2 diabetes or pre-diabetes
- Obesity or a sedentary lifestyle
- A history of smoking
- A family history of early heart disease or stroke
Identifying arterial thickening early allows timely interventions such as lifestyle adjustments or medical treatment to reduce the risk of future cardiovascular events. The test can also be repeated over time to monitor the effectiveness of treatment or lifestyle changes in slowing the progression of atherosclerosis.
How Is a CIMT Test Performed?
A CIMT test is usually carried out in the following steps:
- You will lie on an examination bed while a small amount of gel is applied to the neck.
- A high-resolution ultrasound probe is placed over the carotid arteries to capture images.
- The thickness of the intima and media layers of the artery wall is measured, and any plaque deposits are assessed.

Are There Any Risks of a CIMT Test?
A CIMT test is considered a very low-risk procedure because it uses ultrasound, which does not involve radiation or injections. The scan is painless, and most people experience no discomfort apart from the cool sensation of the gel on the skin. Rarely, slight pressure from the ultrasound probe may cause temporary mild discomfort in the neck, but this passes quickly.
What Do CIMT Test Results Mean?
CIMT results show the thickness of the carotid artery wall and whether plaque is present, compared with what is expected for your age group.
- Normal result – The artery wall thickness is within the expected range for your age, and no plaque is detected.
- Increased thickness – The intima-media layers are thicker than average, suggesting early arterial changes and increased cardiovascular risk.
- Plaque detection – The presence of plaque indicates more advanced atherosclerosis, which raises the risk of stroke and heart disease.
The findings are interpreted alongside your overall health profile, and follow-up tests, lifestyle adjustments, or treatment may be advised if needed.

How Does a CIMT Test Compare with Other Heart Tests?
A CIMT test helps detect early signs of atherosclerosis before symptoms appear and complements other tests that assess different aspects of cardiovascular health, including heart structure, electrical activity, blood flow, and calcium buildup.
Test | What It Measures | Purpose |
---|---|---|
Electrocardiogram (ECG) | Electrical activity of the heart | Detects rhythm irregularities, signs of previous heart damage, and conduction problems |
Stress Test (with ECG) | Heart performance during exercise or medication-induced stress | Assesses how the heart responds to strain and detects reduced blood supply |
2D Echocardiogram | Heart chambers, valves, pumping action, and blood flow | Evaluates heart structure and function, and detects valve disease or heart failure |
CT Calcium Score | Calcified plaque in the coronary arteries using CT scanning | Evaluates risk of coronary artery disease by detecting calcium deposits |
CT Coronary Angiography (CTCA) | Detailed images of coronary arteries using a CT scan with contrast dye | Identifies narrowing or blockages in the coronary arteries |

Frequently Asked Questions (FAQ)
A normal CIMT score means the artery wall thickness falls within the expected range for someone of the same age and sex. Values above this range suggest early arterial thickening, and the presence of plaque indicates more advanced atherosclerosis. It is best to discuss with your doctor or cardiologist, who will interpret the results in relation to your overall health profile and risk factors.
A CIMT test can be worthwhile for people with cardiovascular risk factors such as high blood pressure, high cholesterol, diabetes, or a history of smoking, as it helps detect early arterial changes before symptoms appear. It may also be repeated to monitor whether treatment or lifestyle changes are slowing the progression of atherosclerosis. It is advisable to consult a doctor or cardiologist to decide whether CIMT or another cardiovascular assessment is more appropriate for your situation.
CIMT testing does not follow a fixed schedule and is usually repeated if there are ongoing risk factors such as high blood pressure, high cholesterol, diabetes, or a history of smoking, or when monitoring the effectiveness of treatment or lifestyle changes in slowing atherosclerosis. The recommended frequency varies between individuals, so you should consult your doctor or cardiologist for guidance based on your cardiovascular risk profile and overall health.
A CIMT test screens for early thickening of the carotid artery walls and the presence of plaque, which are early signs of atherosclerosis and linked to a higher risk of cardiovascular disease. It does not directly diagnose heart attacks or strokes but provides an assessment of arterial health that can guide further evaluation or preventive strategies.
Yes, CIMT can detect early signs of atherosclerosis by measuring subtle thickening in the carotid artery walls before symptoms develop. This makes it useful for identifying individuals at increased risk of cardiovascular events. However, CIMT is one part of a broader cardiovascular assessment and should be interpreted together with other risk factors and investigations.
A CIMT scan at healthscreening.sg is priced at $163.50 NETT, inclusive of GST, with consultation fees starting from $49.05. CIMT is generally not covered by MediSave or insurance schemes. The test typically takes about 30 to 60 minutes at our clinic during off-peak hours, and your results will be reviewed and explained by our doctor.
A CIMT test is non-invasive and generally painless because it uses ultrasound technology. The scan involves applying gel to the neck and moving a probe over the carotid arteries to capture images, which most people find comfortable apart from the cool sensation of the gel. Occasionally, light pressure from the probe may cause temporary minor discomfort, but this usually resolves immediately after the scan.
The most appropriate test to detect blocked arteries depends on the location and severity of suspected disease. A carotid ultrasound is commonly used to check for narrowing or blockages in the neck arteries, while CT coronary angiography and invasive angiograms are used to examine the heart’s arteries. CIMT does not diagnose blockages directly but is useful for identifying early arterial changes. It is advisable to consult a doctor or cardiologist to determine the right test for your needs.
A blocked artery in the neck may not cause noticeable symptoms until blood flow is significantly reduced. When symptoms occur, they can include sudden weakness or numbness on one side of the body, vision changes, slurred speech, dizziness, or even transient ischaemic attacks (mini-strokes). If you experience these symptoms, it is advisable to seek urgent medical attention, as they may indicate a serious underlying condition.
Yes, there are several alternative tests to CIMT that assess cardiovascular health. These include carotid ultrasound to evaluate blood flow and blockages, CT calcium scoring to measure calcified plaque in the heart arteries, and CT coronary angiography for detailed imaging of coronary artery narrowing. Each test provides different information, and CIMT is mainly used to detect early arterial thickening. It is advisable to consult a doctor or cardiologist to determine which tests are most appropriate for your risk profile and clinical needs.
A CIMT score may improve or stabilise by managing cardiovascular risk factors through lifestyle changes and, when appropriate, medical treatment. Key measures include controlling blood pressure, lowering cholesterol, managing diabetes, quitting smoking, maintaining a healthy weight, and staying physically active. Improvements reflect healthier artery walls over time, though results vary. It is best to consult your doctor or cardiologist for personalised guidance on maintaining cardiovascular health.
A CIMT test is generally considered reliable for measuring the thickness of the carotid artery walls and detecting plaque when performed correctly. It provides useful information about early arterial changes but does not predict heart attacks or strokes with complete certainty. For this reason, CIMT is usually interpreted together with other risk factors and cardiovascular assessments.
Atherosclerosis cannot usually be completely reversed, but its progression can often be slowed or stabilised with lifestyle changes and medical treatment. Steps such as lowering cholesterol, controlling blood pressure, improving diet, exercising, and quitting smoking may reduce the risk of further arterial thickening or plaque buildup, and partial regression of plaque is possible in some cases. It is best to consult your doctor or cardiologist for personalised guidance on treatment and management.
Yes, lifestyle changes can help stabilise or improve CIMT scores by slowing the progression of arterial thickening. Helpful measures include following a balanced diet, exercising regularly, maintaining a healthy weight, controlling blood pressure and cholesterol, managing diabetes, and avoiding smoking. These changes support healthier arteries over time. Always follow the advice of your doctor or cardiologist regarding the management and treatment of your condition.
