CECT-derived imaging feature analysis for a 70-year-old male ESCC patient without LVI. The tumor was located in the lower esophagus and had a postoperative pathological stage of pT3N0M0 (G2). a Axial CECT image shows a tumor with homogeneous enhancement and regular margin (white and black arrows) without EVFDT or tumor necrosis. b The tumor narrowed the lumen, and the Thickness is 1.3 cm (2.6 cm/2). c The maximum length of the tumor was 3.60 cm, as measured on the sagittal image. d–f The CTVTumor was 55.72HU = (60.19HU + 56.70HU + 50.28HU)/3. g–i The CTVNormal was 41.62 HU = (41.15HU + 41.58HU + 42.13HU)/3. The ΔTN was 14.1HU = 55.72 HU-41.62 HU. The TNR was 1.39 = 55.72HU/41.62HU
