ABSTRACT
<p><b>OBJECTIVE</b>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.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>CT first-pass MPI at rest could detect myocardial ischemia with an accuracy similar to that of MPS.</p>
