Impact of monochromatic coronary computed tomography angiography from single-source dual-energy CT on coronary stenosis quantification.
In coronary CT angiography (CTA), stenosis evaluation is limited by artifacts such as blooming. Monochromatic reconstructions from single-source dual-energy coronary CTA have shown to reduce image noise and improve image quality. ⋯ The use of monochromatic reconstructions improves the overall accuracy of lesion assessment. Combining reconstructions at 90 keV for calcified and partly calcified lesions and at 140 keV for noncalcified lesions yielded optimal results. Thus monochromatic reconstruction bears the potential to improve accuracy of coronary CTA.
