- “ Although our data demonstrate that the dual-energy CTPA protocol maintains high SNR and CNR, we are cautious about its appropriate application, as we do note a slight reduction in image quality and increased image noise. Future integration of iterative reconstruction and other noise reduction tools in dual energy CT may
allow for further improvements in image quality.”

compatible SNR, CNR, and effective radiation dose. Although our data demonstrate that the dual-energy CTPA protocol maintains high SNR and CNR, we are cautious about its appropriate application, as we do note a slight reduction in image quality and increased image noise. Future integration of iterative reconstruction and other noise reduction tools in dual energy CT may
allow for further improvements in image quality.”
