  • “ In conclusion, preliminary evidence on the assessment of myocardial ischemia and infarction by DECT as an addition to coronary CT angiography suggest that DECT is a promising step toward comprehensive evaluation of coronary heart disease with a single noninvasive modality.”

  • “ New technology combining dual energy CT with the latest gemstone detectors for spectral imaging (GSI) can be used to synthesize monochromatic images that mimic images as if different monochromatic x-ray sources were used.”

  • “ In coronary CTA with low radiation technique (mean radiation dose, 1.8 ± 0.7 mSv), GSI with monochromatic reconstructions (65-75 keV) and ASIR (40-60%) offers significant noise reduction and image quality improvement.”
