AB Magnetic  resonance  imaging  (MRI)  relies  on  the  intrinsic  spin  of  protons.  When  protons  are  placed  in  a  magnetic  field,  they  tend  to  align  their  magnetic  poles  along  the  axis  of  the  magnetic  field.  They  can  also  absorb  and  then  re-emit  electromagnetic  radiation  in  the  form  of  radiofrequency  signals.  The  nuclei  of  cells  absorb  energy  from  radiofrequency  pulses  and  may  resonate  from  the  pulses.  This  resonance  induces  orientation  to  the  magnetic  field.  The  frequency  of  the  pulse  required  to  generate  resonance  of  the  target  is  determined  by  the  strength  of  the  magnetic  field  and  the  chemical  properties  of  the  target.
