Why do I have symptoms of dementia but a CT scan showed nothing?

Computed Tomography (Definition)

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

What should I do if I have symptoms of dementia but a CT scan showed nothing?

What should I do if I have symptoms of dementia but a CT scan showed nothing?

Nothing: Imaging cannot diagnose "functional" problems, such as dementia, etc. Imaging such as ct/ MRI can only assess anatomy. It is common to have a normal study with dementia. ...Read more

Would dementia show up on MRI or cat scan?

Would dementia show up on MRI or cat scan?

Not necessarily: Mri and cat scans show anatomical brain changes only, not functional ones. If a dementia is far enough advanced to change brain structures, it would "show up" on these scans. However, there may be a long decline in brain function before that point is reached. There are functional scans which might detect changes before anatomic anomalies can be seen. A normal MRI does not "rule out" dementia. ...Read more

Can dementia be seen with ct? If so what changes would be evident?

Can dementia be seen with ct? If so what changes would be evident?

Very advanced, yes: A very advanced dementia would likely show cerebral cortical atrophy and enlarged ventricles. Earlier in the process you might not see anything at all, though -- because a ct scan registers only anatomic changes, not functional or physiological ones. These may go on for a long time, and could also result in symptoms -- long before anatomic changes show up on ct. ...Read more

Would MRI or CT show dementia ar alzheimers?

Would MRI or CT show dementia ar alzheimers?

Sometimes: Head ct and MRI can show shrinkage in certain brain areas, if that is extensive enough. However. Deterioration of brain function in the form of dementia -- including alzheimer's -- develops and impacts the person's behavior long before physical effects show up on ct or MRI scans. These scans would be only part of a workup for possible dementia, not the whole of it. ...Read more

How are mr scan and a CT scan different?

Contrast difference: Ct uses a combination of xrays shot from multiple directions to look at differences in tissue density. Mri uses strong magnetic fields instead of xrays to differentiate tissues and gives much better contrast than ct. Ct is typically used in the acute setting to see if there is blood or major abnormalities. Mri is a more specific exam to differentiate abnormalities such as stroke or tumor. ...Read more

I am getting a CT scan what should I expect?

Pretty easy: As in the picture, you will lie on a table which will then slide you into and out of the scanner during the scan. The scanner loos kind of like a big donut. Not nearly as long and narrow as an MRI scanner. Depending on the scan you may be asked to drink barium oral contrast before the scan to opacify the bowel lumen. Also, you may or may not have IV contrast injected during the scan. ...Read more
