Study on 110 patients with hepatobilliary lesions, who underwent 3 phases dynamic CT of the liver. WBC test, serologic methods using ELISA and were scored following BCT scale in Thanh Hoa hospital from 2011 to 2013. 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. So, Fascioliasis has some typical images on 3 phase dynamic CT and the value of diagnosis gets better if the combination of 3 phases dynamic CT and BCT scale.
