Everything You Need to Know About Contrast-Enhanced Ultrasound

Contrast-enhanced ultrasound (CEUS) is a type of ultrasound imaging that uses a contrast agent to improve the quality of the images. This type of imaging is used to diagnose and monitor a variety of medical conditions, including cancer, heart disease, and liver disease.

When is contrast-enhanced ultrasound performed?

Contrast-enhanced ultrasound is typically performed when a standard ultrasound is not able to provide enough information to make a diagnosis. It is also used to monitor the progression of a medical condition or to assess the effectiveness of a treatment.

Who performs a contrast-enhanced ultrasound?

Contrast-enhanced ultrasound is typically performed by a radiologist or a sonographer.

How does contrast-enhanced ultrasound work?

Contrast-enhanced ultrasound works by using a contrast agent, such as a gas or a liquid, to improve the quality of the images. The contrast agent is injected into the patient’s bloodstream and then circulated throughout the body. The contrast agent helps to make the images clearer and more detailed.

What happens during a contrast-enhanced ultrasound?

During a contrast-enhanced ultrasound, the patient will be asked to lie on a table and the ultrasound transducer will be placed on the patient’s body. The contrast agent will then be injected into the patient’s bloodstream and the ultrasound images will be taken.

Routine Ultrasound

A routine ultrasound is a type of imaging that uses sound waves to create images of the body. It is used to diagnose and monitor a variety of medical conditions.

Contrast-Enhanced Ultrasound

Contrast-enhanced ultrasound is a type of imaging that uses a contrast agent to improve the quality of the images. It is used to diagnose and monitor a variety of medical conditions.

How do I prepare for the test?

Before a contrast-enhanced ultrasound, the patient should inform their doctor of any medications they are taking, as some medications can interfere with the contrast agent. The patient should also inform their doctor of any allergies they may have, as some contrast agents can cause allergic reactions.

What are the risks of this test?

The risks of contrast-enhanced ultrasound are generally mild, but there is a risk of more serious side effects.

Mild Side Effects

Mild side effects of contrast-enhanced ultrasound include nausea, vomiting, and itching.

Moderate Side Effects

Moderate side effects of contrast-enhanced ultrasound include difficulty breathing, chest pain, and hives.

Severe Side Effects

Severe side effects of contrast-enhanced ultrasound include anaphylaxis, a life-threatening allergic reaction.

How often do side effects from the contrast occur?

Side effects from the contrast agent are rare, but they can occur. The risk of side effects increases with the amount of contrast agent used.

When should I know the results of the test?

The results of the contrast-enhanced ultrasound will typically be available within a few days.

Everything You Need to Know About CIMT Tests

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.
