Fig. 5

Male, 37 years old, with a comprehensive clinical diagnosis of CD, non-moderate-to-severe group. (a) depicts the slope parameter mapping (SPI40–100) during arterial phase, with a corresponding SPI40–100 value for ROI of 2.1. (b) depicts CT value of virtual monoenergetic image of 40 keV (HU40keV) during arterial phase, with a corresponding HU40keV value for ROI of 181.2Hu. (c) shows a colonoscopy view of the terminal ileum, showing irregular ulceration of the mucosa, slightly longitudinal, obvious congestion and edema of the surrounding mucosa, and polypoid bulge. SES-CD score: 4, or mild.
