AB Over  the  past  30  years,  cardiovascular  magnetic  resonance  (CMR)  imaging  has  evolved  from  a  technique  used  to  acquire  static  images  of  the  heart  and  chest  into  a  versatile  imaging  modality  for  assessing  many  physiologic  variables  pertinent  to  the  evaluation  of  patients  with  cardiovascular  (CV)  disease.  CMR-based  methods  accurately  measure  left  and  right  ventricular  (LV  and  RV,  respectively)  volumes,  mass,  and  function  and  are  able  to  characterize  the  presence  and  extent  of  myocardial  infarction  (MI)  and  viability.  Hence,  they  now  serve  as  “gold  standard  techniques”  for  assessing  these  metrics.  Increasingly,  CMR  enables  (1)  assessments  of  myocardial  perfusion  in  the  investigation  of  ischemic  heart  disease;  (2)  differentiation  of  the  etiology  of  nonischemic  cardiomyopathies;  and  (3)  characterization  of  congenital  heart  syndromes,  pericardial  disease,  and  cardiac  masses.  The  purpose  of  this  chapter  is  to  review  the  use  of  CMR  in  these  clinical  situations.  Also,  several  advantages  (lack  of  ionizing  radiation,  ability  to  image  in  multiple  tomographic  planes,  high  spatial,  temporal  and  contrast  resolution,  and  reproducibility),1  as  well  as  disadvantages  (primarily  need  for  availability/operator-staff  experience,  less  feasibility  in  claustrophobic  patients,  and  potential  hazards  associated  with  the  magnetic  field)  are  discussed.
