What Is A Mri Of The Brain
What does a MRI of the brain and orbits show? Does it show back of head and spine even if you lay on the back of your head?
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

What if a recent MRI on brain read venous differnetial in the opptiucal lobe, could it be a brain tumor starting have been having trouble speaking?
Question unclear: I'm sorry, your question is just not clear and can't be sensibly answered. A tumor in one of the occipital lobes is not likely to cause difficulty speaking unless it was large enough to be clearly visible on an mri. I think "venous differential" is a mis-quotation. Perhaps the report read "deep venous anomaly" or "venous hemangioma"? These are benign conditions. Ask your doctor to clarify. ...Read moreSee 1 more doctor answer
That depends: Basically to better evaluate the brain and orbits than you would see with a ct scan. Subtle findings are better seen with an mri- and it is frequently ordered after a negative ct scan. The combo 'brain and orbits' MRI is often ordered by physicians looking for signs of multiple sclerosis ( i would ask your doctor why they ordered it ). ...Read more
I feel very lightheaded i don't no what to do had normal MRI of the brain on 4-18-13 scared please he'lp?
You are still too : Young to be concerned about serious medical conditions. Dizziness is a very common complaint among our patients and oftentimes they are benign and not serious. Yours may be from anxiety, panic attacks, drop in blood pressure with sudden standing up or head turning, inner ear problem, sleep deprivation, medication side effect etc.If all work up are negative, then say to yourself, i'm not dying yet. ...Read moreSee 1 more doctor answer
MRI brain w infarct: This study should be discussed thoroughly with the doc. Diagnosis can't be made w/o clinical correlation. An infarct is a stoke, caused by lack of blood flow to the named areas leading to cell death. A l thalamic infarct should result in either behavioral/cognitive changes or sensorimotor deficits, or both. Internal capsule infarct may result in facial paralysis, arm weakness, & sensory loss. ...Read moreSee 1 more doctor answer

What could it mean if MRI of brain showed "moderately severe global atrophy" in one @83yrs old? It was 2 weeks after chemo on 83yrold & had severe uti
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 moreSee 2 more doctor answers
What areas of brain does "mri brain stem w/o dye" image or cover?Is mra included in above and does it like mra image or look for cerebral aneurysm?
Whole brain stem: The MRI would look at your entire brainstem, shown in the picture. The brainstem is the lower part of your brain that controls breathing and heartrate. An mra (magentic resonance angiogram) is not the same, and would be ordered as a separate test with dye injection. An mra looks at blood vessels for aneurysyms, obstructions, or tears, while an MRI looks for tumors, demyelination, or strokes. ...Read moreSee 1 more doctor answer
What does it mean when a MRI (brain) says there are ten small t2 hyperintense foci within the periventricular deep white matter?
MRI: You will be asked to rest on your back and not move your head during the mri. You will be moved into the scanner. The MRI machine has enormously powerful magnets which will orient hydrogen molecules into a single direction. When a when the magnet energy is changed, the hydrogen atoms give off energy which will be picked up by the computer. ...Read more

20-60 minutes: It varies depending on how many sequences are required. A basic scan runs about 20 minutes, but if the scan requires specialized looks at specific areas (such as the pituitary, the temporal lobes, or the orbits), or if additional sequences with contrast agent are needed, it can take significantly longer. ...Read moreSee 1 more doctor answer
