Excerpt

In 2005, Nikolaou et al. [1] published a paper in European Radiology about the assessment of myocardial perfusion and viability from routine contrast-enhanced 16-detector-row computed tomography. The authors reported promising results, however, concluded carefully: “… application of delayed enhancement techniques might be useful. … However, this procedure requires a second delayed CT scan, increasing the radiation exposure of the patient.” …
