From: Non-invasive assessment of coronary artery bypass graft patency using 16-slice computed tomography angiography

  Sensitivity (%) Specificity (%) PPV (%) NPV (%) Accuracy (%)
Overall n = 116 92.8 100 100 84.6 94.8
IMA grafts n = 35 82.8 100 100 50 85.3
SVG n = 77 98.1 100 100 96.3 98.7
Other n = 4 100 100 100 100 100
  1. IMA: internal mammary artery; SVG: saphenous vein graft; PPV: positive predictive value; NPV: negative predictive value.
