CTPA with a conventional CT at 100 kVp vs. a spectral-detector CT at 120 kVp: Comparison of radiation exposure, diagnostic performance and image quality.
European Journal of Radiology Open（2020）
Abstract
•With SD-CT, increased radiation exposure is not present.•In the current study, CTDIvol was lower with SD-CT than with C-CT, even when 100 kVp was used for the latter.•With SD-CT, higher levels of diagnostic performance and image quality can be achieved.•SD-CT may be the system of choice due to the availability of spectral data and thus additional image information.
