A nomogram established using quantitative CT parameters. A Nomogram presented a scoring model using three quantitative CT features, including tumor thickness (THK-tumor), the ulcer-to-tumor ratio (R-ulcer), and HU-min-to-HU-max ratio (R-HU). B Axial pre-therapy, contrast-enhanced MDCT showed an esophageal cancer with deep ulcer (arrow). The THK-tumor was 17 mm, corresponding to a point of 35 in nomogram. R-ulcer was 0.588(10 mm/17 mm), corresponding to a point of 60. R-HU was 0.35 (30HU/85HU), corresponding to a point of 55. The total points were 150, corresponding to the risk coefficient of 0.7, indicating the high risk of esophageal fistula. C Enhanced CT showed that the patient developed esophageal fistula after chemotherapy (arrow)
