Mild prominence of cortical sulci at the top of the calvarium reflecting minor involutional change. MR brain without constrast otherwise unremarkable.

Mild prominence of cortical sulci at the top of the calvarium reflecting minor involutional change. MR brain without constrast otherwise unremarkable.

MRI Result: This as with all tests should be evaluated by the ordering physician who has the patients history, exam findings and reasons for ordering the study in hand. This allows appropriate interpretation of the study. ...Read more

I experience sudden loss of depth perceptin and my vision seems flat. 2 normal brain MRIs w/o contrast. Where else should we look?

I experience sudden loss of depth perceptin and my vision seems flat. 2 normal brain MRIs w/o contrast. Where else should we look?

See eye MD: Loss of depth perception is uncommon. It can be due to eye or brain factors. It seems the brain factors have been eliminated. Now you should focus your attention on eye factors, like alignment issues. For this, you should see an ophthalmologist. ...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

Early August I got a brain scan with contrast and came back normal...is it possible that now 2 months later tumor developed?

Early August I got a brain scan with contrast and came back normal...is it possible that now 2 months later tumor developed?

Anthing possible: But
1) while I do not know much about you, I assume that you had an indication for the (NEG) scan.
2) http://www. Cancerresearchuk. Org/cancer-info/cancerstats/types/brain/incidence/uk-brain-and-central-nervous-system-cancer-incidence-statistics#By2

I was wondering is gadolinium contrast necessary for a brain mra?

I was wondering is gadolinium contrast necessary for a brain mra?

Usually it: Improves diagnostic accuracy and has fewer "allergies" than iodinated contrast. If I were getting a head mr, i'd for sure take it. ...Read more

Does a brain MRI need contrast to look at chirari?

Does a brain MRI need contrast to look at chirari?

No: Noncontrasted MRI is the test of choice to radiographically diagnose Chiari's. Be aware that there is something called PHASE-CONTRAST MRI or abbreviated PC-MRI. This imaging technique can be used (and is very useful in some cases when looking at headaches associated with Chiari's) to image the malformation. It DOES NOT utilize IV-contrast though the word "contrast" is in the name of the test. ...Read more

Would a brain MRI without contrast show everything?

Would a brain MRI without contrast show everything?

No: Imaging studies do not show "everything".
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex.
Get HPV vaccine. ...Read more

Is an MRI of the brain with contrast the same thing as an mrv?

Is an MRI of the brain with contrast the same thing as an mrv?

MRV: Mri of the brain evaluates the brain tissue for any abnormal signal, lesions, or masses. An mrv (mr venography) uses special sequences to look at the venous structures (dural venous sinuses) around the brain. The main indication for mrv is to look for a clot or stenosis. Typically this is also done with IV contrast for better image quality. ...Read more

Would an MRI of the brain for MS lesions be acceptable without contrast? No we’re lesions found, however, no contrast was used.

Would an MRI of the brain for MS lesions be acceptable without contrast? No we’re lesions found, however, no contrast was used.

It depends.: In the initial evaluation of suspected MRI, contrast is recommended for several reasons, such as the detection of potentially confounding diagnoses (e.g. leptomeningeal processes) that may be invisible on noncontrast MRI, and also for classification/prognostic information if MS is present. For follow up of known MS, contrast may or may not be necessary depending on the clinical situation. ...Read more

Brain MRI in august was normal, getting another one next week for mri with contrast, what are the chances this one will be abnormal with the contrast?

Brain MRI in august was normal, getting another one next week for mri with contrast, what are the chances this one will be abnormal with the contrast?

Unable to answer. The: Answer depends on your condition & what the doctor thinks is the diagnosis. If the original MRI truly didn't show an abnormality, then 99% of diagnoses won't show just because you repeat with contrast. (U run the risk of contrast exposure for no reason). Your question is complex. Use HealthTap Prime or talk to ur prescribing doctor about alternative ways to get diagnosed based on symptoms, not MRI ...Read more

Brain MRI without contrast - what kinds of things might be missed without contrast?

Brain MRI without contrast - what kinds of things might be missed without contrast?

Tumors and anuerysms: A tumor may not be seen unless contrast is administered. Also, any abnormality of the arteries or veins of the brain may not be visible without contrast. Contrast improves specificity and sensitivity of the MRI and should be used when possible. ...Read more

Had MRI of iac without contrast could this pick up a brain tumour or does it just look at inner ear? Scan results were clear? Still have symptoms.

Had MRI of iac without contrast could this pick up a brain tumour or does it just look at inner ear? Scan results were clear? Still have symptoms.

Certain tumors: The MRI that you had only looks at a specific region in your head. It's usually done to look for specific tumors, like a vestibular schwannoma (tumor on the nerve of balance), so it won't pick up tumors that are not in the imaged area. ...Read more

If brain mr/mra with/without contrast detects 2 mm pca infundibula, can it also detect 2 to 3 mm brain arterial aneurysm if there is one in same study

If brain mr/mra with/without contrast detects 2 mm pca infundibula, can it also detect 2 to 3 mm brain arterial aneurysm if there is one in same study

It should.: If the study has enough fine (spatial) resolution to see the infundibulum then it should be able to see an aneurysm. Should is the key word. There are many reasons on MRI that something may or may not be seen and the arteriogram (angiogram) is the real final diagnostic study. ...Read more

Will an MRI of the brain and IAC without contrast show my sinuses? My ENT ordered this exam due to severe nasal congestion and facial pressure.

Yes: Paranasal sinuses are usually also seen on MRI of brain. Osseous structures are usually less well seen and better defined on CT. MRI is so sensitive for soft tissue changes that sometimes patient is not symptomatic. ...Read more

If I had a pituitary adonema would a standard brain MRI with and without contrast show it?

If I had a pituitary adonema would a standard brain MRI with and without contrast show it?

Maybe: Pituitary adenomas MRIs are very specific protocols. If you have a 'macroadenoma' which is larger than the normal gland, a routine MRI protocol would still likely show this. However, 'micoadenomas' can be only a few millimeters in size and a routine brain protocol MRI could miss it based on scan slice thickness or it may not stand out within the normal tissue. ...Read more
