目的　评价影像学和血清学技术在包虫病确立诊断中的作用。方法　对 16 0例小儿包虫病人进行影像学 (B超、X线 )和血清学技术 (EL ISA、IHA)检查分析。结果　包虫病诊断符合率分别是 B超 94.96 %、X线87.5 %、EL ISA85 .38%、IHA 6 4.33% ,假阳性数分别为 B超7例 ,X线 4例 ,EL ISA1例 ,IHA无。结论　特异性较高的血清学实验和形态较好的影像学技术都不能独自对包虫病作出确定诊断 ,只有将它们结合互补才能获得正确的诊断 Objective To evaluate the role of imaging and serological techniques in the diagnosis of hydatid disease. Methods 160 cases of children with hydatid disease were examined by radiography (B-mode, X-ray) and serological techniques (ELISA, IHA). Results The diagnostic rates of hydatidosis were 94.96% for B ultrasound, 87.5% for X-ray, 85.38% for EL ISA and 4.33% for IHA, respectively. The number of false positives was 7 cases of B ultrasound, 4 cases of X ray, 1 case of EL ISA, no. Conclusions Both high specificity serological tests and better imaging techniques can not make a definite diagnosis of hydatid disease alone. Only when they are combined with each other can they get the correct diagnosis
