title: Optimum energy for performing CT iodinated constrast studies.
abstract: A study has been made of CT contrast for iodine as a function of X-ray energy from 80 to 140 kV constant potential. The EMI CT 1010 scanner was used for phantom measurements of contrast signal, noise, artefact and dose. The results show that optimum detectability occurs at 80-100 kV, with the close efficiency being somewhat better at 80kV.
