Radiation Dose

  • "Volume Dual Energy (VDE) works by rapidly switching between 80 and 140 kVp with each gantry rotation, while operating in axial cine mode. The software enables a conventional (single source) 64 detector CT scanner to produce 2 different kilovoltage energies nearly simultaneously during a single imaging acquisition."

  • "Using the current Volume Dual Energy software, radiation doses with DECT were higher than those with SECT imaging. Substantial radiation dose savings are possible when DECT imaging if virtual noncontrast imaging reconstruction replaces precontrast imaging."
