This research aims to compare the accuracy of low-iodine quantification and contrast-to-noise ratio across various dual-energy CT techniques.
Conducted a phantom study using three dual-energy CT techniques.
Measured low-iodine concentration quantification accuracy on iodine maps.
Evaluated contrast-to-noise ratio (CNR) for each technique using a CT abdominal protocol.
All techniques accurately quantified iodine concentrations on iodine maps.
Rapid kV-switching technique had the lowest limit of detection (LOD) and limit of quantification (LOQ).
Dual-layer detector showed superior image quality indicated by higher CNR at 40 keV.

Implication

Phantom study compares iodine quantification accuracy and image quality in dual-energy CT techniques, suggesting implications for imaging precision.

Abstract

All DECT techniques accurately quantified iodine on iodine maps. Rapid kV-switching provided the lowest LOD and LOQ, whereas the dual-layer detector offered superior image quality in terms of CNRnorm derived from VMI at 40 keV in CT abdominal protocol setting.
