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
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
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
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 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
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
