B: Multislice CT scanner images calcification of the right coronary artery. (Provided by GE Medical Systems)
C: Three-dimensional visualization of interior of stent placed in the left anterior descending coronary artery. Visualization of electron beam angiography study performed with AccuImage 3D workstation software. (Provided by Imatron and Heartscan Milwaukee)
D: PET documents reversible myocardial ischemia. Perfusion defect in the anterior wall (yellow area, second column, bottom) almost completely reperfuses at rest (second column, top). Quantitative calculations showed that the ischemic area covers 32% of the anterior wall under stress but only 2% at rest. The ischemic area that can regain normal cardiac function through revascularization appears in white (third column, top). (Provided by Crawford Long PET Center, Emory Healthcare, Atlanta)
