Fig. 4

A 33-year-old female with no apparent clinical diagnosis in control group. (a) depicts the slope parameter mapping (SPI40–100) during arterial phase, with a corresponding SP40–100 values for ROI of 1.2. (b) depicts CT value of virtual monoenergetic image of 40 keV (HU40keV) during arterial phase, with a corresponding HU40keV value for ROI of 104.6 HU. (c) illustrates a colonoscopy image of the distal ileum revealing no mucosal abnormalities.
