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

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?

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 about the lowest risk age group. The more common (slow growing, NON-mailgnant) type is most likely to show up (meningioma,or pituitary) ...Read more
