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 moreSee 1 more doctor answer
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
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 moreSee 2 more doctor answers
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
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 moreSee 2 more doctor answers
Which is the most accurate test to measure stenosis of
the Carotid Arteries expressed in percentage or grading , CT ,MRI, CTA or Ultrsound?
Yes, generally: Ultrasound is the best screening tool for carotid disease. It is non-invasive and gives flow data in real time. Carotid ultrasound is advised for people with multiple risk factors (age over 65, high blood pressure, high cholesterol, diabetes, strong family history, smoking), people with symptoms of stroke or an abnormal noise (bruit) in the neck on exam. ...Read moreSee 1 more doctor answer
I have spasms in what feels like my left carotid artery I had an ultrasound of it a year ago what could this be should I be worried ?
My doctor heard no bruits in my carotid arteries. Could there be any benefit, still, to an ultrasound of them?
If I have had an ultrasound of my carotid artery and it's unremarkable, what could a pulsating lump in my neck be?
I have to jave a ultrasound of my carotid artery. What would be wrong with carotid if it causes swelling of left sife of neck amd face?
More of a vein prob: The artery takes blood from the heart to the brain, the veins drain the blood from the brain back to the heart. If there is something blocking the return flow (the vein) then the increased pressure in the vein makes some fluid leak into the surrounding tissues. Also, the lymph channels drain down and those can get blocked and cause swelling. Many things can cause this, be sure to get all the tests. ...Read moreSee 1 more doctor answer
Stroke 1yr ago surgeon said he could operate on my Carotid Arteries that are about 50% Blocked,when would a second Ultrasound be done from original?
Get a second opinion: That a surgeon says he can operate on your carotid artery that's 50%. Blocked is different from SHOULD it be. Typically 50% lesions are not intervened on either surgically or interventionally! Second has cause and effect been established? Your history states mitral valve repair - do u have any history of arrhythmia for instance? Last, another carotid US is definitively warranted to confirm severe ...Read more
Carotid artery disease, different results from duplex ultrasound vs. Ct angiogram (cta), is that possible?
Carotid artery disease, what to believe, if different results from duplex ultrasound vs. Ct angiogram (cta)?
Excellent: Ultrasound duplex imaging of the cervical carotid arteries is very good at determining significant arterial narrowing. Changes in the flow patterns of the carotid arteries can also suggest disease in the internal carotid arteries further on in at the skull base even though the arteries themselves cannot be seen at that level. ...Read more
My ultra sound for carotid artery showed, "mild noncalcified plaquenin carotid systems bilaterally" should I be worried?-(healthy 70 year old male)
No: Only when the obstruction is around 70% or higher we recommend surgery ( endarterectomy or scraping of the plaques ) but we order an mra or dsa to confirm it . In the mean time you could take 81 mg of Aspirin (if not allergic or contraindicated )and lower your cholesterol as much as you can.. ...Read moreSee 1 more doctor answer
I got a CT scan and a sonogram a year ago for my arteries to heart and carotid arteries; both of them came clear. Could arteries have blockage one year later?
Where can i get the most accurate visual look at the aorta and how it also ascend into the carotid arteries?
Is a stethoscope quite accurate way for listening for bruit in Carotid Artery
from a Cardiologist?
Stethoscope: In gods, careful examination a stethoscope can be an effective screening tool. However, the human ear will miss critical blockage and it is better to use ultrasound and Doppler for more accurate assssment ...Read more
If I have negligible plaque in the carotid and peripheral arteries, do I need to get a carotid ultrasound?
Yes: Yes. Ultrasounds of the carotid arteries are very accurate. We typically look for blockages in the artery. We actually like to see "thin" (non-diseased) walls of the arteries. When we see thickened carotid artery walls in patients, this considered a marker for cardiovascular disease. (carotid intima-media thickness). ...Read moreSee 1 more doctor answer
Should an 83 y/o being treated for hypertension and high cholesterol who suffered a TIA 4 years ago have an ultrasound of the carotid arteries?
Arteries are defined as blood vessels which carry blood away from the heart (to either the body or lungs). Arteries: higher pressure, thicker walls, stretch (pulse) with each heart contraction & deliver blood to the arterioles which control the flow to individual capillaries. Veins are blood vessels which carry blood from capillaries back to the heart (body to right heart; ...Read more
