Myocardial hypo-enhancement on resting computed tomography angiography images accurately identifies myocardial hypoperfusion

Color and gray-scale myocardial CTP using resting CTA images identified myocardial infarction with high sensitivity as well as infarction or ischemia with high specificity and positive predictive value without additional testing or radiation. Color and gray-scale CTP had slightly better specificity than gray-scale alone.
