Phantom-based quantification of the spectral accuracy of lower extremity vascular imaging using a second-generation dual-layer spectral CT at 100 kVp and 120kVp

Abstract Background This study quantitatively evaluated the effects of tube voltage, CTDIvol, energy level, and iodine concentration on the performance of lower-extremity vascular imaging using a second-generation dual-layer spectral CT (DSCT). We further assessed the potential for reducing radiatio...
