A carotid intima-media thickness (CIMT) test is a non-invasive imaging test used to measure the thickness of the inner two layers of the carotid artery. This test is used to detect the presence of atherosclerosis, a condition in which plaque builds up in the arteries and can lead to stroke or heart attack.
Who should get a CIMT test?
The CIMT test is typically recommended for people who are at risk for atherosclerosis, such as those with high cholesterol, high blood pressure, diabetes, or a family history of heart disease. It is also recommended for people who have already had a stroke or heart attack.
How does a carotid intima-media thickness test work?
The CIMT test uses ultrasound imaging to measure the thickness of the inner two layers of the carotid artery. The test is painless and takes about 10 minutes to complete.
How do I prepare for the test?
Before the test, you should avoid eating or drinking anything for at least four hours. You should also avoid smoking or drinking alcohol for at least 12 hours before the test.
How is a CIMT test performed?
The test is performed by a technician who will place a small ultrasound probe on your neck. The technician will then use the probe to measure the thickness of the inner two layers of the carotid artery.
What should I expect after the test?
After the test, you should be able to resume your normal activities. There is no recovery time needed after the test.
What are the risks of this test?
The CIMT test is a non-invasive procedure and is generally considered safe. However, there is a small risk of bruising or discomfort at the site of the ultrasound probe.
What type of results do you get?
The results of the CIMT test will show the thickness of the inner two layers of the carotid artery. If the results are abnormal, it may indicate the presence of atherosclerosis.
When should I know the results of the test?
The results of the CIMT test are usually available within a few days.
If the results are abnormal, what are the next steps?
If the results of the CIMT test are abnormal, your doctor may recommend further testing or treatment. This may include lifestyle changes, medications, or surgery.
When should I call my doctor?
If you experience any pain or discomfort during or after the CIMT test, you should contact your doctor.
