AB Stress/rest  myocardial  perfusion  imaging  (MPI)  is  commonly  used  for  the  diagnostic  assessment  of  patients  with  suspected  coronary  artery  disease  (CAD)  and  for  aiding  clinical  management  decisions,  such  as  the  need  for  myocardial  revascularization  versus  medical  therapy.  The  latter  use  is  facilitated  by  the  well-documented  relationship  between  the  extent  and  severity  of  stress-induced  myocardial  perfusion  abnormalities  and  the  risk  for  subsequent  adverse  cardiac  events.  Despite  these  utilities,  stress/rest  MPI  imaging  has  an  important  limitation:  while  myocardial  perfusion  abnormalities  are  useful  for  assessing  the  hemodynamic  significance  of  obstructive  coronary  stenosis,  many  patients  with  normal  stress/rest  MPI  studies  have  a  substantial  magnitude  of  subclinical  coronary  atherosclerosis,  which  cannot  be  detected  because  they  are  not  flow-limiting  in  magnitude.1,2  Coronary  artery  calcium  (CAC)  scanning  is  a  complementary  test  that  can  detect  subclinical  atherosclerosis.
