Re: _BOB sez.......................

 So, slander me all you want, I really don't give a hoot

First of all slander is a false statement knowingly being made. Being that I posted facts this is not slander. Secondly you must give a hoot or you would not have responded so angrily again.

Lookee what I found. This blog is by _BOB:

Ooohhhhh, a blog article. Gee I can find links to the contrary just as easy:

What Are The Risks Of An MRI?

  • Because MRI uses low-energy, non-ionizing radio waves, there are no known risks or side effects. In fact, since the technique uses no radiation, it can be repeated with no known adverse effects.


  • While there are no known hazards, MRI is not proven to be safe during pregnancy. If a pregnant woman must undergo an MRI, she will be asked to sign a special consent form.


  • The magnet at the center of the procedure may affect, or be affected by, any person fitted with a pacemaker, hearing aid, or other electrical device. People with such devices should advise the physician or technician. They are generally advised not to have an MRI."



The Food and Drug Administration1 recently reclassified the magnetic resonance imaging (MRI) scanner from a class III to a class II device and issued revised guidelines for the safe clinical use of this imaging modality. Along with the reclassification, the previously recommended conservative levels of exposure to the electromagnetic fields required for MRI were relaxed significantly.

The new recommended safe levels of exposure are as follows: static magnetic fields, 2 T; gradient magnetic fields, 6 T/s or less; and radiofrequency magnetic fields, exposure should not produce a core temperature increase in excess of 1°C or localized heating to greater than 38°C in the head, 39°C in the trunk, or 40°C in the extremities.

No long-lasting, hazardous biologic effects have been observed, and none are anticipated from acute or short-term exposures of humans to the static magnetic fields currently used in commercially available MRI scanners.2-4
