Fig. 2 — Conventional linearly blended late arterial (LA) and portal venous (PV) phase dual-energy CT scans (A and B, respectively) LA and PV iodine maps (C and D, respectively) were created using dedicated postprocessing software. Iodine concentration measurements in both phases and Hounsfield unit (HU) measurements were obtained by placing ten regions of interest (ROI, 5 mm²) in surgically proven ischemic and ten ROI in surgically proven non-ischemic bowel segments, respectively. Values were automatically computed by the postprocessing software.
