Would a CT scan show cysts in the brain? If so, would a dr mention them if seen during a brain CT scan after a head injury from a car accident?

Would a CT scan show cysts in the brain? If so, would a dr mention them if seen during a brain CT scan after a head injury from a car accident?

It would: Ct scans of the brain can provide detailed information about brain pathology, thus providing more information related to injuries and/or diseases of the brain. Findings could bleeding, brain injury and skull fractures in patients with head injuries. However, MRI will be more precise for details of soft tissue.

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 does a CT scan of the brain without contrast show?

What does a CT scan of the brain without contrast show?

Some things: CT scan of brain without contrast shows basic anatomy of brain, gray white matter differentiation, ventricles, and physiologic calcifications. Ventricles enlarged/ hydrocephalus, mass effect with displacement of normal structures, some bleeding, abnormal calcifications in tumors or old subdural hematomas, fractures. CT with contrast adds enhancement of certain lesions not seen, hyper/hypo vascular.

What could be wrong if a CT scan shows brain abnormalities?

What could be wrong if a CT scan shows brain abnormalities?

CT sees many things: Ct is most commonly used to look for a stroke, bleed, cancer or traumatic injury. Ct can see many other things which are too numerous to list.

Would a CT scan show if sjogren's syndrome is affecting my brain?

Would a CT scan show if sjogren's syndrome is affecting my brain?

No: Sjogren's syndrome can be diagnosed by antibody testing and minor salivary gland biopsy. A ct scan will not show sjogren's syndrome. It can have a lot of systemic symptoms in some people, but generally not on the brain itself.

How is a lhermitte duclos tumor detected? Would it show on CT scan of brain?

How is a lhermitte duclos tumor detected? Would it show on CT scan of brain?

Maybe: L'hermitte-Duclos disease is a very condition that is not cancerous by itself. Since the majority involve the cerebellum, that is not a strong point for CT imaging because of the bones. They get in the way. Under certain conditions it may be visible. MRI is now a days the way to go.

Can you please tell me if a CT scan of brain would show signs of Dyplastic gangliocytoma?

Can you please tell me if a CT scan of brain would show signs of Dyplastic gangliocytoma?

MRI is better: MRI is the best imaging study for dysplastic gangliocytoma. Many are visible on CT scans, but the abnormality is much better visualized and characterized on an MRI.

What types of brain tumors won't show up on a CT scan?

What types of brain tumors won't show up on a CT scan?

Small low grade mass: Some small low grade tumors that have not incited vasogenic edema could be missed on ct scanning. The addition of IV contrast would improve visualization of some tumors, but ct has limits in resolution when compared to mri. These are not the tumors that cause profound symptoms, frequently these small tumors are found incidentally when patients have scans for other reasons.

Can CT scan without contrast show any brain tumors?

Can CT scan without contrast show any brain tumors?

Sometimes: Brain swelling, hemorrhage and mass effect can be noted on a head ct without contrast. Also, some tumors have calcification a which can be seen in a head ct. Smaller and lower grade tumors can sometimes be missed on a head ct without contrast.

Brain scan with lots of white matter show on CT scan, why?

Brain scan with lots of white matter show on CT scan, why?

Not clear: Your question is not clear. White matter is normally present in the brain. Was there something specificly commented on about the white matter on your scan?

I had a ct scan of my brain today. Is it normal to have a graph over top of the imagine then the next image without the graph shows a bright white spot?

I had a ct scan of my brain today. Is it normal to have a graph over top of the imagine then the next image without the graph shows a bright white spot?

What????: Would you strike out into the wilderness with no camping or hiking experience, & having never looked at a topographic or hiking map? And then you take a first look at the map and are immediately confused? So what do you do? Post a question on HikeTap? This is analogous, except the knowledge gap in medicine is way, way wider. Just relax and wait for the report.

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.

Can CT scan without contrast show brain aneurysm?

Unlikely: Ct scan without contrast is unlikely to show an aneurysm unless it is very large and is calcified. A ct angiogram is a better study to visualize an aneurysm.

Will a ct scan show whether I have a brain aneurysm?

Will a ct scan show whether I have a brain aneurysm?

Yes: Has to be a CTA (CT angiogram). CT scan of the head without contrast doesn't detect aneurysms unless they are larger. CT scan of the head with contrast has a slightly better chance. CTA of the head is good for seeing aneurysms. See radiologyinfo. Org and stroke association. Org for more details.

Can a regular CT scan of the brain show blocked arteries?

Indirectly: Can see stroke changes which suggest blocked arteries. Need contrast ct, preferably cta to see arteries.

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.

Would a plain CT scan show an unruptured aneurysm in the brain?

Would a plain CT scan show an unruptured aneurysm in the brain?

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.

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...

Ct scan shows mild brain atrophy & chronic white mater disease? Is this serious?

It depends.: In a young person that would be cause for concern. However, in elderly individuals these are common findings.

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.

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
