电子束CT血流序列在复杂性先天性心脏病诊断中的应用

Using the flow mode of electron beam computed tomography in the diagnosis of complex congenital heart disease

目的：探讨血流序列（ＦＬＯＷ）在影像诊断和血流动力学分析上的独特作用，评价电子束ＣＴ（ＥＢＣＴ）对先天性心脏病的诊断价值。方法：应用ＥＢＣＴ以ＦＬＯＷ对１１例复杂的先天性心脏病患者进行检查。结果：１１例患者共发现原发畸形２７处，其中室间隔缺损９例，房间隔缺损２例，大动脉转位４例，右弓右降３例，三尖瓣闭锁１例，肺动脉瓣狭窄７例，动脉导管未闭１例。结论：ＥＢＣＴ对先天性心脏病病变程度较重、低血流的血管检查具有重要的诊断价值。

Objectives:The individual effect of flow mode in imaging diagnosis and blood dynamics is discussed.The diagnosis value of electron beam CT(EBCT) on congenital heart disease is evaluated. Methods:Flow mode of EBCT was performed on 11 patients with complex congenital heart disease. Results:Twenty seven primitive deformations were found in 11 patients.They include 9 cases of VSD,2 cases of ASD,4 cases of transposition of great arteries,1 case of closure of tricuspid valve,7 cases of pulmonary stenosis,1 case of PDA. Conclusions:EBCT is a new valuable examining method for congenital heart disease with serious deformation and lower blood flow.
