Carotid Intima-Media Thickness (CIMT) Test
What Is Carotid Intima-Media Thickness Test?
The CIMT test uses ultrasound technology to measure the thickness of the inner two layers (intima and media) of the carotid arteries. It detects early signs of atherosclerosis, a condition where arteries narrow due to plaque buildup from fats, cholesterol, and other substances, restricting blood flow. CIMT is a non-invasive predictor of cardiovascular diseases like heart attacks and strokes, allowing for timely intervention. In 2022, cardiovascular disease was a significant health concern in Singapore, with approximately 23 deaths occurring daily and accounting for 31.4% of all deaths locally.
Given that cardiovascular disease is a leading cause of death in Singapore, early detection allows preventive measures such as lifestyle modifications, medications, and other interventions that can reduce the risk of serious health complications and potentially save lives.
Procedure for CIMT Test
CIMT test is generally performed as follows:
- Preparation: The patient should remove all neck jewellery and obstructions and stand in a relaxed position.
- Application: A gel is applied to the neck area. This gel ensures good contact between the transducer and the skin, eliminating air pockets that could distort the ultrasound waves and affect image quality, ensuring clear and precise imaging.
- Ultrasound: The transducer is moved along the carotid artery. The technician carefully manoeuvres the probe to capture high-resolution images of the artery walls.
- Measurement: The thickness of the intima and media layers is measured from the ultrasound images. The measurements are typically taken at multiple points along the carotid artery to ensure accuracy.
- Analysis: The collected images and measurements are analysed by the doctor to assess the presence and extent of atherosclerosis.
Interpreting CIMT Results
An increased intima-media thickness indicates a higher risk of atherosclerosis. The doctor will review these results, consider the patient’s overall health, lifestyle, and risk factors, and determine the best course of action for preventing cardiovascular disease. Possible interventions can include lifestyle modifications such as dietary changes and increased physical activity, medications to manage cholesterol and blood pressure, and regular monitoring to track the progression of atherosclerosis.
CIMT vs. Other Cardiovascular Tests
CIMT is a non-invasive, safe, and quick procedure that specifically measures the thickness of the carotid artery walls, focusing on early detection of atherosclerosis. This differs from other cardiovascular tests, each with its unique purpose:
- Electrocardiogram (ECG): Measures the electrical activity of the heart to detect arrhythmias, heart attacks, and other cardiac conditions.
- CT Coronary Angiography (CTCA): Uses computed tomography (CT) scans to provide detailed images of the heart’s blood vessels, assessing for any blockages.
- CT Calcium Scoring: Uses computed tomography (CT) scans to detect the buildup of calcified plaque in the coronary arteries.
- Stress Tests: Evaluate heart function under physical stress, useful for detecting significant blockages and assessing overall cardiovascular fitness.
Each of these tests complements CIMT by providing comprehensive insights into different aspects of cardiovascular health and risk for cardiovascular-related diseases.

Summary
The CIMT test is a valuable, non-invasive tool for early detection of atherosclerosis, essential in managing cardiovascular health. In Singapore, where cardiovascular disease is a leading cause of death, regular CIMT screenings can identify early artery narrowing, allowing for timely interventions. By complementing other cardiovascular tests, CIMT offers comprehensive insights into heart health, aiding in the prevention of serious cardiovascular complications and improving patient outcomes. If you are unsure if CIMT is suitable for you, schedule an appointment with our doctors to discuss more about your cardiovascular health.
