Question 1

can a ct scan find a brain tumor?

Accepted Answer

Brain tumor: Some kinds of tumors are better diagnosed by ct and some by mri. Are you having issues with headaches, etc? You should see a doctor if you have any symptoms that make you worry about brain tumor.

Question 2

could ct scan cause a brain tumor?

Accepted Answer

Rare: Many ct scans of the head can theoretically cause brain cancer several years later. See radiology physicist at your hospital to calculate your dose and risk if you had many head ct scans.

Question 3

can a full body ct scan find a brain tumor?

Accepted Answer

Definitely: A head CT will pick majority of brain tumors, in the range of 90-95% with MRI even better as far as resolution.

Question 4

what happens if my ct scan didn't show the brain tumor?

Accepted Answer

MRI: Mri with and without contrast is more sensitive for detecting tumors that ct is.

Question 5

what's the likelihood of a ct scan missing a brain tumor?

Accepted Answer

Depends: If done without contrast, it could be missed.   If the tumor is in the posterior fossa (back of brain or brainstem) could be missed.  With a ct scan, the bones in the back of the head commonly cause artifact and a mass could be missed.  If there is a concern, then a MRI with gadolinium should be performed.  But a ct scan with contrast is a good study.  Hope this helps.

Question 6

non contrast ct scan show growing brain tumor, what is wrong?

Accepted Answer

Need more evaluation: It is very difficult to diagnose a brain tumor on a non-contrast ct scan.  I would recommend getting a brain MRI with contrast (called gadolinium).  Mri takes a much better look at the brain than does ct.

Question 7

ct scan did not show brain tumor. does that mean i'm in the clear?

Accepted Answer

No: Mri of the brain with gadolinium [contrst medium]  may need to be performed... Before ruling out that you do not have brain tumor...

Question 8

what kind of brain tumor would not show up on a ct scan? why would it not be seen?

Accepted Answer

Many: Many types of brain tumors do not show up on ct scans, especially if it was done without IV contrast because they can look the same as normal brain tissue.  Mri with and without gadolinium contrast is the best way to evaluate the brain for a tumor.

Question 9

can anyone of you drs give me a website link of a ct scan with contrast showing a brain tumor?

Accepted Answer

Brain tumor: It is possible but is very unlikely. Specially if  the symptoms you have now are the same you had 2 1/2 years ago. Discuss your symptoms with your doctor. He may be able to determine what is the problem causing your symptoms and relief you level if anxiety.
