An Adult and Pediatric Size-Based Contrast Administration Reduction Phantom Study for Single and Dual-Energy CT Through Preservation of Contrast-to-No

This phantom study provides a quantitative framework for a change in protocol to address the contrast shortages. This method is either lowering kV in single-energy CT (SECT) or using lower energy virtual monochromatic images (VMI) from dual-energy CT (DECT), which reduces ICM dosage while preserving the iodine contrast-to-noise ratio. The findings of this study provide a quantitative baseline for other institutions for their scanning protocols.
