Hi,

Which frequencies does an MRI machine use? Is it microwaves?
Would prolonged exposure to it be damaging to the body?

The actual signal information that is used for reconstructing the MRI images comes from radio-frequency (RF) magnetic fields, oscillating millions of times per second (MHz range).

The FDA and other advisory bodies have recommendations for limiting things such as the rate of switching of the RF gradient fields and the RF power levels, but I think the current consensus is that these things do not pose serious risks to the patient as used in MRI.

That was wonderful.

Nuclear Magnetic Resonance imaging is actually a very advanced concept....it involves quantum mechanics and was worthy of a nobel prize.

Enjoy the reading
