Notes, ADC, apparent diffusion coefficient; D, pure diffusion coefficient; D*, perfusion-related incoherent microcirculation; f, microvascular vol fraction. The normal oesophageal wall is defined as T0-staged tumour. Normal, and T1, T2, T3, T0–1, T0–2, T1–3, T2–3 represent normal oesophageal wall, and the T1, T2, T3, T0–1, T0–2, T1–3, T2–3 stages of oesophageal squamous cell carcinoma, respectively.
adenotes significant difference in the parameters between stages after Bonferroni correction (p < 0.05).
