AB Computed  tomography  (CT)  is  a  technique  that  can  fully  evaluate  both  cardiac  structure  and  function.  Recent  advances  in  imaging  allow  for  evaluation  of  not  only  relatively  stationary  anatomy,  such  as  the  thoracic  aorta,  but  also  rapidly  moving  structures,  such  as  the  myocardium  and  coronary  arteries.  This  imparts  the  ability  to  noninvasively  evaluate  for  significant  coronary  artery  disease  (CAD),  myocardial  and  pericardial  abnormalities,  and  aortic  pathology.  When  combined  with  electrocardiographic  (ECG)  gating,  freeze-frame  images  of  the  heart  can  be  obtained,  eliminating  most  of  the  motion  artifact.  This  is  particularly  important  in  contrast-enhanced  CT  angiography  (CTA)  of  the  coronary  arteries  and  in  quantification  of  coronary  artery  calcium.  Advances  in  spatial  and  temporal  resolution  and  image  reconstruction  software  have  also  helped  in  the  evaluation  of  cardiac  structures  such  as  coronary  veins,  saphenous  vein  grafts,  atria,  ventricles,  and  pulmonary  arteries  and  veins,  helping  precisely  define  their  spatial  relationships  within  the  cardiovascular  system  and  allowing  for  a  comprehensive  assessment  of  a  variety  of  cardiovascular  disease  processes.  This  chapter  details  the  current  and  future  role  of  cardiac  CT  for  the  assessment  of  cardiovascular  physiology  and  pathology.
