A 41-year-old member asked:

can a person keep his dentures (fixed) on while going for mri (magnetic resonance imaging)?

Yes: A fixed denture refers to a permanently cemented bridge which is solidly attached to a tooth or teeth. Ferrous metals which can be attracted to a magnet are not used in dentistry so it should not be an issue in any case. The big concern is small slivers of ferrous metal embedded in soft tissue (think slivers from metal work) that pose a risk because they can become shrapnel in an MRI machine.

Yes: If your denture contains no metals, there should not be a problem. Ferromagnetic items pose problems for mris. A full denture does not normally have metal within it. Some full dentures have metal re-enforcement and should be removed. Most partial dentures also have metal clasps or frameworks and should be removed. All metals can distort MRI images and should be removed.

Maybe: If you have fixed teeth on imlants -- yes you can. If you have dentures held in with paste you can. If you have any type of metal in the teeth which is subject to magnetic pull, then you cannot. Need to find out what you have. Check with your dentist and the imaging center.

Yes : Provided there is no metal in your denture you are ok to take a mri.

What are EEG and MRI used for in evaluating seizures?

2 doctor answers3 doctors weighed in
Dr. Felix Brizuela
Neurology 32 years experience
Function and structu: Eeg confirms whether or not there is a short circuit that could be detected in the brain to confirm whether you are having seizures. Many times, however, the short circuit is missed on routine eeg.If we are suspicious enough, sometimes we just treat. Mri helps to see if you can identify the cause of the short circuit. Such as an old stroke, scar tissue due to trauma or something more serious.

How long does it take for a brain mri?

Dr. Julian Bragg
Neurology 17 years experience
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.

What are the dangers caused by a brain mri?

MR imaging is safe: There are no inherent dangers caused by the magnetic field on the brain. However, a number of items can interfere with mr imaging and some may be hazardous, these include older brain aneurysm clips, cardiac pacemakers/aicd/defibrillators, implanted medicine pumps, tens unit, bullet fragments/pellets/shrapnel, embolization coils, etc. Claustrophobic patients find MRI difficult to without medication.

What can a mra detect that a brain MRI cannot detect?

3 doctor answers9 doctors weighed in
Dr. Jonathan Dissin
Neurology 39 years experience
Vascular disease: Mra looks at moving blood in the arteries of the brain and can help in the diagnosis of vascular narrowing from atherosclerosis, or anerysms, and arteriovenous malformations (avm). Though an MRI may detect large aneurysms and if contrast is given suggest avm, mra is much more sensitive than MRI when investigating vascular anatomy. Mra does have its limits, small aneurysms can't be detected.

MRA are always improved by doing them at higher field strength. 3T is the best clinically available strength for MRA.

Are partial dentures a good alternative to implants?

11 doctor answers16 doctors weighed in
Dr. Earl Sandroff
Dentistry 43 years experience
They do work: Partial dentures (fixed & removable) have been around a lot longer than implants. Even tho implants are the standard of care they do have their drawbacks. Very expensive. They are very good but for those who can't afford them partial dentures do very well in most cases. If the partial dentures are your only bet, then many do their best to get used to them and make them work.
