在世界许多地区包括欧洲、亚洲、加勒比海岸地区及南美洲均有人体片吸虫病病例报道。在慢性感染病例中,由于虫种的低繁殖率,即使采用合适的寄生虫学技术通常也难以检测到粪便中的虫卵,因而肝片吸虫病的诊断非常困难。超声检查是一种比较经济的影像学检查方法,广泛应用于肝片吸虫病流行区。本文系统研究了超声检查用于肝片吸虫感染诊断的价值和通过连续的超声学检查方法研究超声检查对经药物治疗后病人的监 Human cases of schistosomiasis are reported in many parts of the world, including Europe, Asia, the Caribbean coast and South America. In chronically infected cases, diagnosis of Fasciola hepatica is very difficult due to the low reproductive rate of the parasite, which is often difficult to detect even in the stool with appropriate parasitological techniques. Ultrasound is a more economical imaging method, widely used in the prevalence of fistulae. This article systematically studied the value of ultrasonography for the diagnosis of Fasciola hepatica infection and evaluated the effect of ultrasonography on patients after drug treatment by means of continuous ultrasonography
