Comparison of diagnostic efficacy between routine CTE at 120 kVp + VMI at 60 keV and routine CTE at 120 kVp in CD diagnosis. A comparison of the ROC curve showed that the combined tests improved the diagnostic efficiency of CD with an increase in the AUC from 0.82 (routine CTE at 120 kVp) to 0.88 (routine CTE at 120 kVp + VMI at 60 keV) with statistical significance (P < 0.001)
