Question 1

why do i have symptoms of dementia but a ct scan showed nothing?

Accepted Answer

Not sensitive: Ct is insensitive and nonspecific for dementia. Mri and pet are better, but clinical evaluation by a neurologist is most important.

Question 2

ct scan showed 8mmx5mm brain calcification in left cortex. said its benign, they also said could be 2 possible conditions. 1: calcified cavarnoma or 2. longstanding dystrophic cortical calcification. i read one can cause haemorrhage and 1 dementia??

Accepted Answer

: Presumably you didn't just wander into a CT center and made an impulse purchase. A doctor ordered this for a reason. What was the reason? The CT scan isn't the patient; you are. The doctor who ordered it is ethically obligated to explain the results to you in terms you can understand, or if (s)he can't, to send you to someone who can.

Question 3

would dementia show up on mri or cat scan?

Accepted Answer

Yes: Generally brain imaging will show atrophy/shrinking of the brain. Imaging may also help to rule in or out other causes.

Question 4

can dementia be seen with ct? if so what changes would be evident?

Accepted Answer

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.

Question 5

would mri or ct show dementia ar alzheimers?

Accepted Answer

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.

Question 6

can ct see brain atrophy from alzheimer's or dementia?

Accepted Answer

If advanced, yes: If alzheimer's or other dementia is far enough advanced, then ct can show cortical atrophy and enlarged ventricles.  However, functional brain changes can be going on for a long time before anatomical changes show up.

Question 7

price of a ct scan?

Accepted Answer

Depends. : It entirely depends on what you are getting a ct scan of. Ct examination can sometimes involve contrast and multiple scans. In addition, each place has their own pricing. Surprisingly, you can find the same ct be priced differently in the same town. However, not every place has the same quality either. I would ask around to try to find a good balance between quality and price.

Question 8

what exactly is a ct scan?

Accepted Answer

Computed Tomography: uses a system of rotating x-ray and detectors, and digital data processing, to produce detailed images of various body parts.  The patient ls positioned on a table and passed thru the rotating tube housed within a circular gantry.

Question 9

what is it like getting a ct scan like?

Accepted Answer

Easy: You lie on a platform which moves into the ring of the ct scanner. The exam usually takes less than a 2 minutes. You feel nothing but may be asked to hold your breath during the exam. Sometimes contrast medication is given into a vein to make body parts easier to see. Other than the mild sting of having a catheter put in a vein, most patients don't notice the injection of contrast.

Question 10

how are mr scan and a ct scan different?

Accepted Answer

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.
