Figure 5a.

Stress perfusion imaging in a 53-year-old woman with chest pain on exertion and at rest. (a) From left to right in the top row, basal, mid, and apical short-axis cine MR images of the LV show normal global and regional left ventricular systolic function (LV ejection fraction, 61%). In the second row, adenosine stress perfusion images of the same LV locations as in the top row show severe subendocardial perfusion defects involving all myocardial segments. In the third row, the rest perfusion images of the same LV locations are normal. In the fourth row, the LGE images of the same short-axis LV locations show a small focus of enhancement that may represent a microinfarction or an embolic infarction in the mid to apical inferior wall. (b, c) Left anterior oblique (LAO) (b) and LAO caudal (c) invasive coronary angiographic images show severe proximal and distal right coronary artery stenoses on the LAO view (arrows in b), as well as severe stenosis of the distal left main coronary artery on the LAO caudal view (arrow in c).
