Can a magnetic resonance imaging test have any bad effects on bady, if so, what could be such effects?

None proven

Pacemakers
Though many people have claimed side effects ranging from tingling to fatigue to a change in hair color, there are no proven side effects of MRIs. Never the less, effects on the fetus of a pregnant woman are unknown. People with some implanted electric devices such as pacemakers may not have MRIs.

Dr. Meng K. Syn answered:

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

Yes

Mri
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.

Dr. Stephen Berns answered:

Can a high-powered magnetic resonance imaging scanner cause cancer to patients or staff?

No known association

Cancer
MRI relies on changing nuclear atomic spin, and does not change the chemical bonds of molecules, which can alter DNA and cause cancer. However, the use of a contrast agent in patients called gadolinium during the procedure may induce the onset of a debilitating malady commonly known as NSF/NFD. This can cause fibrosing throughout the body. http://www.medscape.com/viewarticle/550783

How long does the magnetic resonance imaging take?

Depends

Mri
length of an MRI study depends on what area(s) of the body is/are being imaged, whether the study is done without & with contrast, whether any complications occur during the study (some people get very nauseated from contrast rapidly infused), whether you move during the study, how comfortable you are lying very still for several minutes, if there are unexpected reactions to the contrast
