Can A Regular Ct Scan Of The Brain Show Blocked 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
Can a heart scan CT calcium score show the presence of soft plaque in the arteries. If not, can an CT angiogram sans catheter do the job?
Yes: Soft plaque does contain calcium, so it will elevate the calcium score. CTA can estimate (key word: estimate) the degree of blockage. Researchers have tried to make predictive instruments that incorporate calcium scores. Check this one out sponsored by the NIH: http://www.mesa-nhlbi.org/Calcium/ArterialAge.aspx ...Read more
USUALLY NOT: Since aneurysms are a 'defect' in the arterial system --they can really only be seen with a contrast ct study (angiogram) or a mra (mri-angiogram). One time i did have a patient with a leaking brain aneurysm which the effects of which were barely visible on ct but confirmed on mra--and she made it! ...Read moreSee 2 more doctor answers
Doubtful: A standard CT scan of the brain would have challenges in determining inner ear issues or blood flow per se. Additional modifications would be needed for the latter (along with the appropriate clinical symptoms), and other types of scans would be better for evaluation for the former (e.g. MRI, again, with the appropriate symptoms). ...Read more
Also, very fast!: Agree with excellent answer above. Additionally, ct scans have the advantage of being much faster than MRI scans, and they are much more widely available- if you come into a small hospital's er at 3 in the morning, they will likely be able to do a ct immediately, while an MRI might wait until the next morning (if it is available at all!). ...Read moreSee 3 more doctor answers
Will a CT angiogram of the coronary arteries reveal a pulmonary embolism or other lung disease and is it harmful to have 2 CT scans in the same month?
It might: A CT angiogram or the coronaries might show a pulmonary embolism, provided that the radiologists obtained full field of view reconstructions (some do not) and the pulmonary embolism is not higher or lower than the field of view. most often, the answer would be yes, a significant PE would be identified on this type of scan. having two ct's in the same month is not optimal, but likely of no harm. ...Read more
Not well: A contrast enhanced exam is necessary to assess the coronary arteries in a meaningful way in young patients. Cardiologists use contrast for catheterization, but noninvasive coronary angiography with contrast is preferable. Read more about ct scans and contrast here: http://www.Conciergeradiologist.Com/ct-scan-with-contrast.Html mri would be a way to go without contrast but lacks detail of ct. ...Read moreSee 1 more doctor answer
Is it possible for a CT scan of the head *without* contrast to show an unruptured brain aneurysm?
Magnetic resonance : An MRI of the brain shows the blood vessels indirectly because the moving blood creates a "signal void". A magnetic resonance angiogram of the brain shows the arteries more directly. The vessels may be detected through the administration of contrast or may be detected due to the movement of blood within the vessels. This latter phenomenon is referred to as flow related enhancement. ...Read moreSee 1 more doctor answer
Need contrast: Very difficult to see aneurysms in the brain without contrast. If you are concerned about this as a possibility you should ask your doctor about your risk. ...Read more
Many times: These studies have limited resolution and can miss abnormalities. Mra is better than MRI as it shows the blood vessels better and is useful for screening. Even mra is limited resolution and can miss lesions smaller than 2-3mm. For high suspicion a catheter angiogram is the best study. ...Read moreSee 2 more doctor answers
Ct scan dects brain aneurysms? Is it possible for a CT scan without contrast to reveal an unruptured brain aneurysm? Is the test meant to find that sort of thing?
Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more
Blocked arteries is a condition in which a person has decreased or no blood flow in one or more of his arteries, due to obstructions inside the artery such as thick plaques, floating clumps of broken plaques, blood clots, etc... Severe compression due to a problem on the outside of an artery can also ...Read more
