The results showed that all patients with fascioliasis have typical imaging findings on 3 phases dynamic CT with multiple nodules (up to 2 cm diameter: 93.3 percent). The contrast enhancement of the lesion is evident lesser than the normal parenchyma (more than 94.0 percent) in 3 phases dynamic CT. "Tunnel" sign and subcapsule fluid were also typical image in fascioliasis. 3 phases dynamic CT with Se: 84.0 percent, Sp: 74.3 percent and Ace: 80.9 percent; BCT scale with Se: 90.7 percent. Sp: 77.1 percent. "cut off" 8 and AUC: 90.2 percent in diagnosing fascioliasis.
