title: [An initial study on the feasibility of diagnosing myocardial ischemia with CT first-pass myocardial perfusion imaging at rest].
abstract: OBJECTIVE
  To assess the feasibility and accuracy of CT first-pass myocardial perfusion imaging (CT first-pass MPI) at rest for diagnosis of myocardial ischemia. Results of adenosine-induced myocardial perfusion scintigraphy (MPS) were used as gold standard.
  
  
  METHODS
  Twenty-two patients with suspected or diagnosed coronary artery disease (CAD) were included and CT coronary angiography (CTCA) and MPS were performed within 2 weeks. CT first-pass MPI detected myocardial ischemia results through analyzing the raw date of CTCA were compared with MPS results.
  
  
  RESULTS
  The sensibility, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of CT first-pass MPI at rest for detecting myocardial ischemia were 92% (12/13), 78% (7/9), 86% (12/14), 88% (7/8) and 86% (19/22), respectively.
  
  
  CONCLUSIONS
  CT first-pass MPI at rest could detect myocardial ischemia with an accuracy similar to that of MPS.
