Almost none. There are some surgical procedures a patient may have had done, prior to having an MRI ordered, that will not allow them to have an MRI study. A pace maker would be a good example. The magnetic field can erase or reprogram the pacemaker, and depending on the material used move the pace maker or the wires in the heart.
Most modern surgical implants are safe in MRI machines, but it is safest if you make sure to let the technologist know you have had surgery in the past.
I have read some studies (forgive me I don't remember references) when I was doing MRI that stated that some people could have arm numbness when left inside a strong MRI machine for extended periods of time. This seems to effect men more so than women.
I never experienced this nor met a patient who has. The magnets are large and the biggest problem I have seen with the use of them is patients becoming claustrophobic.
The strength of the magnet is measured in teslas from 1 tesla to 3 tesla. Usually over 3 is not considered safe for humans and is only used in research.
What else can I help you with?
Does an MRI cause dehydration?
No. A magnetic resonance imaging machine does not cause dehydration. However, the medical reason for having the MRI may indeed be causing dehydration. Dehydration is not listed as a side effect on the web site: http://mri-side-effects.net/ Some of the side effects listed are the same symptoms of dehydration, but are not an indication that the patient has lost water. The contrast dye that is injected for some MRI scans may have its own issues though: http://www.levinsimeskaisergornick.com/gadolinium.html

The MRI has been known to cause minor long-term shrinking of the male genitalia. The amount it will shrink it is hardly anything to be worried about, however; as little as 1/10 of an inch for a single MRI. In the worst cases, it's never been more than 1/2 of an inch from a single MRI.

Oh honey, buckle up! Side effects of an MRI are typically mild, like feeling claustrophobic or getting a headache from the loud banging noises.

Just remember, if you start levitating or speaking in alien tongues during your scan, that's probably not a side effect – you might just be a superhero in the making.
