ON THE COVER
On the left, a contrast-enhanced CT angiogram shows a stenotic lesion in the left circumflex coronary artery with faint poststenotic flow. In the center, a coronary angiogram shows the same stenotic lesion. On the right, a 3-dimensional reconstructed multislice spiral CT scan superimposed by a color-coded stress perfusion PET scan shows the coronary artery tree and the shape of the heart. Blue indicates a reversible perfusion defect. This image, by revealing a reduced hyperemic response to adenosine stress in the lateral wall, documents that the lesion seen in the first 2 images is hemodynamically relevant.
