Mri (Definition)

Mri or magnetic resonance imaging is one of the more recently developed imaging modalities available to physicians. It uses powerful magnets to generate images. There is no ionizing radiation which is a major advantage over many other modalities. Mri is the best imaging exam that we have for most soft tissue and joint related problems. There are radiologists ...Read more

Mr of the brain showed foci of abnormal highh signal in deep white matter?

Mr of the brain showed foci of abnormal highh signal in deep white matter?

High signal MRI: This finding in MRI of brain is non-specific. Most of them are due to microvascular disease associated with high blood pressure and diabetes. Some due to old damage. Also can be seen in diseases such as multiple sclerosi. Your doctor will decide if he or she should go further base on your sign and symptoms. ...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

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

Mri of the brain without contrast?

Mri of the brain without contrast?

Maybe safer in some: Gadolinium contrast could potentially cause kidney complications on rare occasion. Mri without contrast will reveal areas of atrophy, stroke, bleeding, tumors, hydrocephalus, etc, but will not clearly show certain ms lesions, aneurysms, avm's, some inflammatory problems, so, always discuss with your doctor as to why an ordered MRI might be done in a variety of ways. ...Read more

Headaches somewhat frequently. MRI brain normal. Go for MRA Brain or MR Spectroscopy of the brain? or MRI other parts? I get free MRI/MRA services.

Headaches somewhat frequently. MRI brain normal. Go for MRA Brain or MR Spectroscopy of the brain? or MRI other parts? I get free MRI/MRA services.

MRA for h/a: MRA would show even small aneurysms, so if you are concerned it may add some additional information about the vessels, including small or stenotic vessels and the carotids. Also consider thyroid, diabetes, musculoskeletal strain ,eyestrain from computer, allergies,sinusitis, food intolerances ( MSG is classic), mitral valve prolapse,hydrocephalus should have been seen on MRI,and migraines. ...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

Minimal increased nonspecific signal in brain white matter. unremarkable MRI of the brain. Can this be nothing in a 26 yr old?

Minimal increased nonspecific signal in brain white matter. unremarkable MRI of the brain. Can this be nothing in a 26 yr old?

Yes: It can be nothing. Lets take a step backwards though. There must have been a reason for getting the MRI. Migraine headache can be associated with tiny punctate white matter changes. Perhaps a bit of clinical information and a look at the scan might be in order. If you can do this I would be glad to help. www.healthtap.com/drericweisman ...Read more

30 week ultrasound showed asymmetrical brain ventricles on fetus. Rest of the scan perfect. Is this a normal variant?

30 week ultrasound showed asymmetrical brain ventricles on fetus. Rest of the scan perfect. Is this a normal variant?

Not really.: No, this is not a normal variant and is usually indicative of some type of compromise and blood flow, to the side of the brain where the ventricle is more prominent. The good news, is that a fetus's brain is very resilient, and as long as all else goes well from here on in, the baby can develop normally. ...Read more

Brain MRI is fine.MRI of whole spine showing supecious intramedullary hyperintensities in cord posterior to bodies of D6 to D8.

This is a: nonspecific abnormality that can be associated with a variety of demyelinating processes including MS. There are usually changes in the brain as well, but not always. Your doctor will interpret these findings in the context of your clinical/laboratory picture. ...Read more

Brain MRI reveals complete opacification of the bilateral frontal and ethmoid sinus, otherwise normal, could this be cause of daily head pressure ?

Brain MRI reveals complete opacification of the bilateral frontal and ethmoid sinus, otherwise normal, could this be cause of daily head pressure

?

Quite possibly: MRI findings suggest sinusitis, probably chronic, depending on duration of symptoms. Discuss with FP or ENT ways of alleviating symptoms—decongestants + NSAID, for example. But ENT may suggest surgery to widen openings to sinuses to promote better drainage. ...Read more

Normal CT of brain within past six mths.Would a symptomatic brain tumor develop quickly since then? Also, normal eye exam and visual acuity tests

Normal CT of brain within past six mths.Would a symptomatic brain tumor develop quickly since then? Also, normal eye exam and visual acuity tests

Unlikely: Unless it is from somewhere else and it is infiltrating type to the tissues. Imagine a speck of tissue not seen six months ago by ct scan. The usual doubling time of a tumor in volume is 3 months. For it to grow and cause symptoms, it has to have been big enough to be seen 6 months ago. ...Read more

Why did a MRI of brain showed "nonspecific white matter"?

Why did a MRI of brain showed "nonspecific white matter"?

Common finding: The scan probably read as "non specific white matter changes" which is can be seen in scans of people with migraine. This is a fairly common statement in a radiology report. The findings should be correlated with your physician's evaluation. There may be a reason to repeat the MRI in six months to a year. ...Read more
