Dual-energy computed tomography colonography using dual-layer spectral detector computed tomography: Utility of virtual monochromatic imaging for electronic cleansing

•Tagging density on VMI at low keV was significantly higher than that on 120 kVp.•VMI can improve the image quality and electronic cleansing performance.•Dual-layer spectral detector CT allows need-based retrospective tagging calibration. To assess the utility of virtual monochromatic imaging (VMI)...
