Coronary CT angiography images

Caption

Coronary CT angiography (CTA) images (left side, A and B) and corresponding derived fractional flow reserve (FFR) (right side, A and B). The location 2-cm distal to stenosis is manually delineated and the coronary CTA–derived FFR (FFRCT) value is registered. The lowest lesion-specific coronary CTA–derived FFR value is used to categorize participants, with (A) greater than 0.80 representing a normal value and (B) 0.80 or less representing an abnormal value.
