Myocardial perfusion imaging and infarct characterization using multidetector cardiac computed tomography

Figure 2 Early assessment of myocardial viability immediately after primary percutaneous coronary intervention in patients with anterior (A) and inferolateral (B) ST-segment elevation acute myocardial infarction. Delayed enhancement of iodinated contrast administrated during percutaneous coronary intervention is observed using non-contrast enhanced cardiac computed tomography, without heart rate control and using a low dose-saving protocol. Discrimination between transmural (A) and subendocardial (B, arrows) extent of the irreversible myocardial damage (delayed enhancement) can be achieved using this technique. LA: Left atrium; LV: Left ventricle; RA: Right atrium; RV: Right ventricle.
