CNR and SNR for esophageal cancer vs. normal esophageal wall in arterial and venous phase. Increasing CNR or SNR values with decreasing energy levels of noise-optimized virtual monoenergetic images can be appreciated. Asterisks indicate statistically significant differences compared to each other. Besides, CNR or SNR values of PEI were significantly lower than MEI (+) 40–80 keV (p < 0.05)
