摘　　要：目的探讨行肝胆平面显像患儿肝脏与心脏的平均计数比值(liver-to-heart ratio,L/H)对诊断结果的影响。方法收集2012年1月~2013年2月间因黄疸于本院行肝胆平面显像新生儿患儿90例,其中65例通过手术病理确诊,25例通过临床随访确诊。回顾性分析所有图像特点,测量并计算每个患儿注射药物后10 min的L/H比值。根据L/H大小,将患儿分为A组(L/H≥1.72)和B组(L/H<1.72),比较两组患儿肝胆动态显像诊断或排除胆道闭锁的正确率。结果 A组患儿肝胆平面显像诊断及排除先天性胆道闭锁的正确率明显高于B组,差异有统计学意义(P<0.05)。结论通过计算肝胆显像10 min的L/H比值,可以直观并且半定量评估图像,尤其要注意L/H比值较低的患儿。Objective To identify the effects of liver-to-heart （L/H） ratio of hepatobiliary scintigraphy in the diagnosis of biliary atresia. Methods Data of 90 infants with jaundice in our hospital from January 2012 to February 2013 were selected. Sixty-five cases were confirmed by pathology and twenty-five cases were confirmed by follow-up study. Characteristics of all im- ages were analyzed, L/H ratio of hepatobiliary scintigraphy in 10 rain of each patient was cal- culated. According to the L/H ratio, the patients were divided into two groups, group A （ L/H ≥ 1.72） and group B （ L/H 〈 1.72）. Diagnostic accuracy were compared （Chi-Square） be- tween group A and group B. Results The diagnostic accuracy in group A was significantly higher than that in group B （P 〈 0. 05 ）. Conclusion Images can be evaluated visually and semiquantitatively by calculating the liver-to-heart （L/H） ratio at 10 rain post injection. More attention should be payed to the patients with lower L/H ratio.
