Photon-Counting CT Enables Lower Contrast Media for Aortic Imaging (IMAGE)
Caption
Comparison of image quality between EID CT with standard contrast media protocol and PCD CT with low-volume contrast media protocol using a matched radiation dose. Transverse and three-dimensional cinematic rendered images from thoracoabdominal CTA in a 71-year-old woman in group 2 are shown. (A–C) Images from third-generation EID CT with automated tube voltage selection of 90 kVp. (D–F) Images from PCD CT with reduced contrast media volume of 52.5 mL and VMI at 50 keV. Time interval between scans was 6 months. CTA = CT angiography, EID = energy-integrating detector, PCD = photon-counting detector, VMI = virtual monoenergetic images.
