| 摘 要： | 目的 探讨双源计算机断层摄影(dual-source computed tomography, DSCT)诊断先天性心脏病(先心病)的临床应用价值。 方法 DSCT增强扫描检查先心病患者20例, 年龄4个月~53岁, 平均19岁; 所有病例均以心脏超声(echocardiography, ECHO)为对照, 并经手术证实。 结果 20例患者经手术证实的心内外结构畸形共63处, DSCT检出59处, 诊断敏感性为93.7%;ECHO检出55处, 诊断敏感性87.3%, 两种方法诊断敏感性比较差异无统计学意义(χ2=1.474, P=0.225)。63处结构畸形中, 心脏部分畸形41处, DSCT检出37处(90.2%), ECHO检出37处(90.2%), 两者敏感性相当(P=1.000);心脏-大血管连接处畸形9处, DSCT检出9处(100%), ECHO检出8处(88.9%), 差异无统计学意义(P > 0.05);大血管部分畸形13处, DSCT检出13处(100%), ECHO检出10处(76.9%), 差异无统计学意义(P > 0.05)。 结论 DSCT能够显示心内外结构畸形, 具有较高的诊断敏感性, 对先天性心脏病, 特别是合并心外大血管畸形的诊断有重要价值。

| Abstract: | Objective To evaluate the value of dual-source computed tomography （DSCT） in the diagnosis of congenital heart disease. Methods Twenty patients aged 4 months to 53 years （mean age 19 years） with congenital heart disease underwent contrast-enhanced DSCT. The results were compared with those of echocardiography （ECHO） and confirmed by surgery. Results Among the 20 patients, DSCT detected 59 of 63 （93.7%） anomalies that confirmed by surgery, and ECHO detected 55 of 63 （87.3%） （χ2=1.474, P=0.225）. In the 41 intracardiac anomalies, DSCT was as sensitive as ECHO （both 90.2%, P=1.000）. In the 9 heart-vessel conjunction deformities, no significant difference was found between the sensitivities of two modalities （100% vs. 88.9%, P〉0.05）. In the 13 great vessel deformities, no significant difference was found between the sensitivities of two modalities （100% vs. 76.9%, P〉0.05）. Conclusion DSCT detects intraand extra-cardiac anomalies with high sensitivity and has an important value in the diagnosis of congenital heart disease especially those with extra-cardiac anomoalies. |
