A, Curved multiplanar reformatted coronary CT angiogram shows ostial calcification with second diagonal branch (arrowhead) and significant stenosis with noncalcified plaque (arrow) in midsegment of left anterior descending coronary artery (LAD).

B, Invasive coronary angiogram confirms presence of significant bifurcation stenosis involving mid LAD (arrow) and ostium of second diagonal branch (arrowhead).

C, Dual-energy CT iodine map obtained during adenosine infusion shows blood-pool defects (arrows) in mid anteroseptal and anterior left ventricular myocardium.

D, Rest perfusion CT image does not show any perfusion defects in left ventricular myocardium.

E and F, Cardiovascular MR images acquired at stress (E) and rest (F) show complete reversible subendocardial perfusion defects (arrows, E) in mid anteroseptal and anterior left ventricular myocardium.
