Multicontrast Multiphase Intestinal Imaging Using Photon-Counting CT
This study successfully demonstrated the capability of PCCT combined with material decomposition to delineate 2 CM and water in rats. The contrast dynamics of the 2 CM in the vessels (aorta and vena cava) and intestines were successfully reproduced in the CM maps. VNC maps may omit the need for CT scans before contrast administration. VMI revealed distinct energy-dependent attenuation profiles of the given materials.
