The presentation of MaRIA assessment by two radiologists. A 49-year-old male patient with Montreal classification of A3B1L1 was classified UG (tCDEIS = 8). A and B, axial DWI sequence (A) and axial T2-weighted single-shot fast spin-echo image with fat saturation (B) presented the abnormality of terminal ileum (arrow). C and D represent pre- and post-enhancement sequences, and the enhancement could be detected of the intestinal wall (arrow). The BWT measured by R1 (the senior) and R2 (the junior) was 4.75 mm, 4.00 mm, respectively, and the RCE assessed by R1 and R2 was 119.7, 93.6 separately. R1 considered that the edema could be detected, while R2 did not. No sign of ulcer was reported in both radiologists. MaRIA evaluated by R1 was 14.52, and 7.87 by R2. Obviously, R1 made an accurate assessment and R2 made an inappropriate diagnosis
