Ct Angiography

  • “ An optimal analysis of thoracic circulation can be achieved on virtual monochromatic spectral images at 60 keV and 100 keV and on the original polychromatic images at 80 kV and 140 kV.”

  • “ The use of low concentration contrast media for dual-source, dual energy CT angiography enables suppression of streak artifacts around systemic veins on high energy images while providing satisfactory central arterial enhancement on low energy images; the additional advantage of this scanning mode is the considerable reduction in the amount of iodine administered to patients.”

  • CT Angiography
    - Improved contrast profile (less contrast needed)
    - Bone subtraction
    - Calcified plaque subtraction
    - Less radiation dose (pseudo-non contrast scans)
