Can Ct Scan damage brain , effect activity of brain?

Can Ct Scan damage brain , effect activity of brain?

No: The x ray radiation in a CT has no measurable or known effect on neural tissues. 1) dose is way too low and 2) nerves are relatively radioresistant since the cells don't reproduce very fast, if at all. There is a theoretical risk of cataracts and cancer years later, but this is incredibly small esp. for a single scan and controversial anyway. ...Read more

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

Can a CT scan of the head without contrast dye detect brain aneurysms?

Can a CT scan of the head without contrast dye detect brain aneurysms?

Yes: While plain ct scan is not the best test for aneurysm, large aneurysms can potentially be spotted. Mri is a better test, especially when blood vessels are looked at as well. ...Read more

What can a CT scan of the brain catch that a brain MRI scan cannot?

What can a CT scan of the brain catch that a brain MRI scan cannot?

Also, very fast!: Agree with excellent answer above. Additionally, ct scans have the advantage of being much faster than MRI scans, and they are much more widely available- if you come into a small hospital's er at 3 in the morning, they will likely be able to do a ct immediately, while an MRI might wait until the next morning (if it is available at all!). ...Read more

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. ...Read more

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. ...Read more

Can a negative ct scan without contrast of the head miss a brain tumor causing headaches?

Can a negative ct scan without contrast of the head miss a brain tumor causing headaches?

Yes, it can: Did you go to an ER with H/A & they did a knee-jerk don't-sue-us CT scan which was normal? If you've had H/As for at least 3 years, the chances of finding a tumor on brain imaging are no greater than for someone with no history of H/A. Are your headaches of recent onset, relentless & worsening? If not, you can find something else to worry about, like the outcome of the 2016 presidential election. ...Read more

Could a mri/ct scan detect all brain injurys?

Could a mri/ct scan detect all brain injurys?

Nope: Sometimes you can see evedence of bleeding. With traumatic brain injury sufficient to cause changes on ct typically survival is markedly reduced. Certain types of MRI done at the right time following a brain injury can sometimes show evidence of cerebral contusion. Much of the damage done with traumatic brain injury is microscopic (too small even with diffuse axonal injury) to be seen on mri. ...Read more

Having MRI to check pituitary tumor growth.Had coiling of aneurysm 3 months ago.Worried the coils could move because of vibration of the scan?Thanks.

Having MRI to check pituitary tumor growth.Had coiling of aneurysm 3 months ago.Worried the coils could move because of vibration of the scan?Thanks.

Check with neurosurg: The concern with mris and aneurysm coils is whether or not they have MRI compatible metal. Generally, the coils that are currently used (at least in the United States) are all MRI compatible. You should check with your neuro-interventionalist or neurosurgeon who placed the coils. Generally the vibration of the MRI is not enough to move the coils. ...Read more

Can head CT scans in an infant cause radiation and learning disabilities?

Can head CT scans in an infant cause radiation and learning disabilities?

Not exactly: A ct is by definition 'radiation', since it is a series of xrays computer reconstructed as sliced pictures of body tissues. It doesn't cause radiation but exposes the person to radiation. Modern ones may expose one to an amount similar to a transcontinental flight over the usa. Repeat exposure is a current topic of concern, but no specific learning disorder has been identified as connected to this. ...Read more

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. ...Read more

Can 2 CT scans of the head cause brain cancer?

Can 2 CT scans of the head cause brain cancer?

Unknown: CT of the brain does deliver radiation but the likelihood of developing malignancy from one or two studies is unknown. One must weigh the benefit to be gained from the study against whatever risk may be present. Careful selection of patients, particularly children is important when considering imaging. Thanks for trusting HealthTap! ...Read more

Will a brain aneurysm show up on a plain CT scan of the head?

Will a brain aneurysm show up on a plain CT scan of the head?

USUALLY NOT: Since aneurysms are a 'defect' in the arterial system --they can really only be seen with a contrast ct study (angiogram) or a mra (mri-angiogram). One time i did have a patient with a leaking brain aneurysm which the effects of which were barely visible on ct but confirmed on mra--and she made it! ...Read more

What is prognostic value of MRI of brain in child with near drowning and normal CT brain?

What is prognostic value of MRI of brain in child with near drowning and normal CT brain?

MRI more accurate: Neuroimaging techniques can add valuable information (MRI) shows characteristic patterns depending on severity of the injury and also timing of imaging. Degree of edema and brain swelling is better seen by MRI than by computer tomography, therefore CT scans are not widely used for early outcome prediction. ...Read more

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. ...Read more

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. ...Read more
