How accurate is carotid artery ultrasound?

How accurate is carotid artery ultrasound?

Very: Carotid ultrasounds are very accurate. Not only can the plaque morphology be evaluated, but the degree of narrowing can be accurately estimated by measuring the peak systolic velocities. Complete carotid ultrasounds also evaluate the vertebral, subclavian and intracranial arteries. Ct angiograms are often done to confirm ultrasound findings prior to surgery. ...Read more

Sonogram (Definition)

An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more

Accuracy of carotid artery ultrasound to detect circ problems and impending cva?

Accuracy of carotid artery ultrasound to detect circ problems and impending cva?

Screening test: Ultrasound is a good screening test for carotid stenosis which is a risk factor for a stroke, however the ultrasound even in an accredited lab is not predictive of risk for stroke. Stroke may be ischemic or hemorrhagic and may not be caused by carotid disease. ...Read more

What is the accuracy of carotid artery ultrasound to detect heart problems?

What is the accuracy of carotid artery ultrasound to detect heart problems?

Depends: Some studies suggest that by using carotid duplex and measuring intima media thickness we can detect early coronary artery disease with sensitivity of 85% but low specificity of 39% . It is a good screening test that is not invasive but not very accurate. ...Read more

If I should have a carotid artery ultrasound, how reliable would the results be?

If I should have a carotid artery ultrasound, how reliable would the results be?

80-90% reliable : Studies have shown that in symptomatic patients and carotid duplex result of 70-99% then this is most sensetive and no more test is needed. If duplex results 50-69% then another test need to confirm that like cta or mra. If the results are below 50% then no need for other studies unless high clinical suspicion that require another study. ...Read more

Had a carotid artery ultrasound and got these numbers, what do they mean, what to do?

Had a carotid artery ultrasound and got these numbers, what do they mean, what to do?

Accurate: Carotid duplex ultrasound is fairly accurate. You did not post numbers in your question. Please see a vascular specialist who can go over the test report with you. ...Read more

Had a carotid artery ultrasound and doctor also heard bruit, what do they mean?

Had a carotid artery ultrasound and doctor also heard bruit, what do they mean?

Narrowing in artery: When there is significant narrowing in carotid artery-that would create turbulant and that can be heard on examination and called carotid bruit. Go to see your doctor and discuss re- ultrasound finding and further management . Good luck. ...Read more

Can the results of a carotid artery ultrasound be applied as an indication of the state of other arteries in the body?

Yes: Ultrasound of the carotid arteries is a very good method to detect vascular disease. This test can diagnose a spectrum of problems from intimal thickening to marked cholesterol deposits (plaque). Disease of the carotid arteries often serves as an indicator of arterial disease elsewhere. ...Read more

Carotid artery ultrasound but no thyroid nodules reported although nodules were detected on a prior scan. Can I trust the scan was done correctly?

Carotid artery ultrasound but no thyroid nodules reported although nodules were detected on a prior scan. Can I trust the scan was done correctly?

Yes, with caveat: A carotid artery ultrasound is typically done with different technique and goals than a thyroid ultrasound. The carotid scan was probably done properly but if you need to re-evaluate a previously seen thyroid nodule I would suggest a thyroid ultrasound. ...Read more

Can you tell me how accurate is portable ultrasound screenings of carotid arteries?

Very: As long as the portable ultrasound screening program is icavl accredited, the results will be 90%-98% accurate. Ultrasounds are operator dependent, that is why it is important that the ultrasound lab follow standard protocols to optimize results. Icavl is an acronym for... Intersocietal commission for the accreditation of vascular laboratories. ...Read more

Artery (Definition)

Arteries are a type of blood vessels. We can divide blood vessels into 2 categories. Arteries are high pressure vessels which deliver (red) oxygen + blood out into the body. Veins on the other hand or low pressure vessels which return (dark) oxygent - blood from the body ...Read more


Carotid Arteries (Definition)

The carotid arteries start in the chest and progress up the sides of the neck. About mid neck they split and one branch supplies blood to the face the, the other continues without branches into the skull and supplies ...Read more
