Can a CT scan find a brain tumor?

Can a CT scan find a brain tumor?

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.

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

Could CT scan cause a brain tumor?

Could CT scan cause a brain tumor?

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.

What happens if my CT scan didn't show the brain tumor?

What happens if my CT scan didn't show the brain tumor?

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

What's the likelihood of a CT scan missing a brain tumor?

What's the likelihood of a CT scan missing a brain tumor?

CT not sensitive: Ct brain is a fast screening exam that is often used in the acute setting such as the emergency room. It is helpful in detecting obvious tumor and mass effect from the tumor. However, it is not sensitive in the detection of small tumor which does not produce mass effect or surrounding brain edema. Mri brain with and without contrast is the best imaging modality for detecting brain tumor.

Non contrast CT scan show growing brain tumor, what is wrong?

Non contrast CT scan show growing brain tumor, what is wrong?

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.

Ct scan did not show brain tumor. Does that mean I'm in the clear?

Ct scan did not show brain tumor. Does that mean I'm in the clear?

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

What kind of brain tumor would not show up on a CT scan? Why would it not be seen?

What kind of brain tumor would not show up on a CT scan? Why would it not be seen?

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.

If CT scan w&wo contrast came back normal with no brain tumor found 2 years and 7 months ago what's my risk to have one now if I have new symptoms?

It depends: It all depends on what kind of tumor was identified over two yrs ago. New symptoms strongly suggest that you need new studies. You should consult your neurologist or primary care m d. An MRI is more sensitive for soft tissue problems then a ct.

Last question I promise 2 years and 7 month ago I got a CT scan with and without contrast and it was clear? D I need to still worry about brain tumor

Last question I promise 2 years and 7 month ago I got a CT scan with and without contrast and it was clear? D I need to still worry about brain tumor

Most: 23 year old men do not need a head ct +/- contrast in the first place, and the exposure from the radiation when you do not need a scan is not worth repeating. Imaging is expensive and should only be done when necessary. You provide no information suggesting either ct or MRI is indicated.

2 years and 8 months ago CT scan w&wo contrast ruled out a brain tumor now im worry again can a brain tumor grow that fast and cause symptoms im 27?

2 years and 8 months ago CT scan w&wo contrast ruled out a brain tumor now im worry again can a brain tumor grow that fast and cause symptoms im 27?

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.

Can a CT scan miss a brain tumor?

Can a CT scan miss a brain tumor?

Yes!: I have seen this happen occasionally when brain tumors occur in the back part of the brain (posterior fossa) where the ct scan can be distorted by the bones. It is rare, however.

What are the odds that a CT scan with and without contrast missed a brain tumor?

What are the odds that a CT scan with and without contrast missed a brain tumor?

Brain tumor: The odds are not very high but if concerns persist that something could have been missed, a brain MRI with contrast is recommended.

Would swelling of brain tissues from brain tumor be shown on a non contrast CT scan?

Would swelling of brain tissues from brain tumor be shown on a non contrast CT scan?

Yes: It is possible to see brain swelling from tumor on non contrast CT. FYI there are better modalities to test for this such as MRI.

Had a CT scan for possible brain tumor how long for my dr to get results? If something was found would I have herd the same day?

Had a CT scan for possible brain tumor how long for my dr to get results? If something was found would I have herd the same day?

Depends: Ct scan interpretations are usually available to the ordering physician the same day, at the latest the next working day. How quickly your physician informs you of the results is highly variable, unfortunately, and can't be predicted without knowing the habits of the individual physician you have.

Had CT scan for brain tumor or bleed friday afternoon. Will I have to agonize all weekend? Is no news good news or was it just too late on a friday?

Had CT scan for brain tumor or bleed friday afternoon. Will I have to agonize all weekend? Is no news good news or was it just too late on a friday?

Don't assume: One would hope for a call, but lack of one doesn't mean anything--so don't read too much into it. Medical staff can drop the ball and leave patients in the dark, especially late on a friday afternoon. Definitely call the office monday morning to be sure.

Can a CT scan miss a brain tumor or mass?

Yes: Ct scans can certainly on occasion miss a small tumor, especially when they are down in the posterior fossa at the base of the skull. Mri scans are more sensitive and less likely to miss a tumor, but even they can on rare occasions miss one that shows up later. These scans are read by human beings, and they can miss something that is there, too.

If I get a CT scan for my sinuses will it also detect a brain tumor if I have one?

Unlikely: A ct of the sinuses includes a portion of the brain, not all of it. So it could miss some areas. Hope this helps.

Could radiation from mobile phones can cause brain tumor 10 or 20 years later? What about a CT scan its much more radiation?

Could radiation from mobile phones can cause brain tumor 10 or 20 years later? What about a CT scan its much more radiation?

No and probably no: Cell phones don't cause brain tumors. There's no biological basis, it's not the kind of radiation that mutates genes, the ongoing talk is driven by politicians, and the studies are such junk that one even had significantly more tumors on the opposite side. Ct scans may make a tiny contribution to glioma incidence but there's no proving in an individual case.

Ct Scan (Definition)

Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...Read more


Neoplasms (Definition)

"tumor" literally translates as "mass", so even a fresh bruise could be called a "tumor". Doctors use the term "neoplasm" (tranlates literally as new growth) to describe tumors that are abnormal growths of cells. These may be benign or malignant; "malignant" = cancer. In everyday usage, we use "tumor" ...Read more
