Could brain MRI detect meniere?

Could brain MRI detect meniere?

You need 3T MRI: Look up 3t MRI and meniere's disease. I would also suggest a 32 channel MRI head coil. ...Read more

Mri (Definition)

Magnetic resonance imaging named for the effects of the strong magnetic field upon the atomic and molecular phase or spin and the image created when that magnetic field is altered and the excited particle changes gibing off a signal that is recorded and interpreted by a complex computer algorithm, ...Read more

Can CT scan diagnose meningitis?

Can CT scan diagnose meningitis?

Not diagnostic: A ct is part of the work up of meningitis. However, a lumbar puncture is the test that typically allows for a diagnosis of meningitis by obtaining cerebrospinal fluid for study and cultures. ...Read more

Is a pituitary MRI different from an MS brain mri?

Is a pituitary MRI different from an MS brain mri?

Merely technical: Looking directly at base of brain and pituitary requires slightly different cuts and angles, as the focus is directed to a small area of brain, but the software and pictures are handled in a similar fashion. In ms, we tend to use specialized approaches, such as flair or double inversion recovery to see the white matter spots better. Not needed for pituitary views, usually. ...Read more

Can MRI with contrast miss brain tumor?

Can MRI with contrast miss brain tumor?

Best test: An MRI with contrast is the best test to detect a brain tumor. If the MRI did not detect a brain tumor then it is likely either too small to see or there is no brain tumor. ...Read more

Would a MRI show brain infection?

Yes, not always : Depends on the type of infection. A larger abscess will be detected. More diffuse infections such as meningitis may reveal characteristic suggestive of an infection. Usually need to combine clinical history, exam, blood tests, CSF analysis +/- ct/mri to make diagnosis of a brain infection. ...Read more

CT Brain shows mass prepontine cistern CPA meningioma. Symptoms consistent with diagnosis. MRI contrast show no lesion. Symptoms persist! Now what?

CT Brain shows mass prepontine cistern CPA meningioma. Symptoms consistent with diagnosis. MRI contrast show no lesion. Symptoms persist! Now what?

Very strange: Not certain what to make of the disparity between the CT scan and the MRI. In some cases, a lesion is so small that it is missed by the artifact created by the thickness of the MRI slices. I would ask your doctor if an MRI of the brainstem with "thin slices" might be reasonable to confirm/refute the CT--with and without contrast. Take care and stay healthy! ...Read more

Could MRI or CT scan detect brain cancer?

Could MRI or CT scan detect brain cancer?

Sure: Mri would be the imaging test of choice, though often we start with a ct. Ultimately, you'll likely need a biopsy to prove it's a cancer. ...Read more

Spinal cord lesion on t3/4, negative brain mri, positive for oligoclonal banding. Neurologist says ms. Can this be with negative brain mri?

Spinal cord lesion on t3/4, negative brain mri, positive for oligoclonal banding. Neurologist says ms. Can this be with negative brain mri?

Can occur: Although less common, isolated spinal cord involvement can be seen in absence of demonstrable brain lesions. But make certain that you do no have NMO presenting atypically, and an anti-aquaporin blood test can help confirm diagnosis. ...Read more

Could a CT scan show any viral infections of brain or spinal meningitis?

Could a CT scan show any viral infections of brain or spinal meningitis?

Lumbar puncture: A lumbar puncture, or lp, is the best and most sensitive way to diagnose meningitis. Ct scans do not always show evidence of CNS infections. ...Read more

Brain scan says possible minor ischemic disease?

Brain scan says possible minor ischemic disease?

Maybe, maybe not: I assume the scan was a mri. I also assume you have had no symptoms of a stroke. This is not uncommon. You should have the MRI abnormality investigated, but the causes may include migraine, hypertension, and demyelination from any number of causes. The abnormality is likely a warning sign of an underlying process that needs to be addressed. Have your physician refer you for evaluation. ...Read more

Would MRI or CT show dementia ar alzheimers?

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. ...Read more

Does getting an MRI reveal brain tumors?

Does getting an MRI reveal brain tumors?

Usually: An MRI is probably the best way to detect a brain tumor in a patient who has symptoms or findings on a medical examination that suggests a brain tumor may exist. Getting an MRI if you are asymptomatic(have no medical issues) is unwarranted and should not be done. ...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

Can cryptococcal meningitis be detected with a brain MRI without contrast?

Can cryptococcal meningitis be detected with a brain MRI without contrast?

Surveillance: is an important tool in the identification of cryptococcal infections in high risk populations. Guidelines can be found here: http://whqlibdoc.who.int/publications/2011/9789241502979_eng.pdf In the general population symptoms and physical findings would result in a diagnostic spinal tap to make a diagnosis. MRI is indicated when the immune status of the infected individual precludes an inflammatory of antibody response. In that situation an MRI WITH contrast is necessary to identify the presence of infection. ...Read more

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. ...Read more

Can an MRI scan show cognitive impairment?

Can an MRI scan show cognitive impairment?

NO: Mri is an imaging device that is independent of function. Think of your car mechanic and a problem with your car. Lifting the hood and looking is like getting an mri. A good mechanic will want to turn it on and drive around and think carefully about what may be wrong. A good brain mechanic will ask appropriate questions and get appropriate tests and think about what may be wrong. ...Read more

Encephalitis (Definition)

The encephalon is considered to be the gray matter of the brain. This is where all the neuron cells are located. If an infection sets in to this region it is called an encephalitis. The -itis ending just means inflammation. It is usually virus infections that like to go specifically to the ...Read more
