摘要
目的 探讨双源CT（DSCT）在法洛四联症（TOF）诊断中的价值.方法 对36例临床诊断为法洛四联症的患者进行DSCT心脏成像检查,患者数据在工作站中经过多平面重建（MPR）、容积再现（VRT）、最大密度投影（MIP）等方法进行分析处理.测量主肺动脉直径（MPA）,左、右肺动脉直径,膈肌平面降主动脉直径,左室舒张末容积,了解冠状动脉走行.结果 34例患者经手术治疗验证,与CT诊断完全符合.2例患者未手术,1例患者为冠脉走行异常,另1例为体肺侧支循环过多.结论 DSCT诊断先心病准确率高,能够发现冠状动脉异常及体肺侧支.DSCT可作为临床诊断法洛四联症的一种常规方法,具有较高的临床应用价值.
Objective To investigate the value of dual-source CT （DSCT） in the Tetralogy of Fallot （TOF） diagnosis. Methods There are 36 patients with a clinical diagnosis of TOF, all of those patients have re- ceived DSCT Cardiac imaging, patient＇s data were analyzed and processed in the workstation through multi-planar reconstruction （MPR）, volume rendering （VRT）, maximum intensity projection （MIP） and other methods, mea- suring the diameter of the main pulmonary artery （MPA）, left and right pulmonary artery diameter, the descending aorta diameter of diaphragm level, left ventricular end-diastolic volume, coronary path. 34 patients were verified by surgery, 2 patients without surgery, one with coronary artery path abnormal, the other with excessive pul- monary collateral circulation. Results DSCT has high accuracy in congenital heart disease diagnosis, coronary artery abnormalities and pulmonary collateral can be found. Conclusion DSCT can be used as a routine method of clinical diagnosis of TOF, with a high clinical value.
