64层螺旋CT对先天性心脏病的诊断价值

目的：探讨64层CT增强扫描及后处理技术对先天性心脏病（CHD）的诊断价值。方法：分析52例经手术证实的CHD患者的64层CT、心脏超声（TTE）和X线心血管造影（CAG）检查资料。结果：手术证实心内外畸形共142处,其中心内畸形54处,MSCT漏诊4处,TTE漏诊2处,CAG漏诊2处,MSCT、TTE和CAG对心内畸形诊断符合率分别为92.6%、96.3%和96.3%,3者差异无显著性意义（P=0.769,P〉0.05）;心脏大血管连接部及心外血管畸形88处,MSCT误诊或漏诊4处,TTE误诊或漏诊24处,CAG误诊或漏诊4处,MSCT、TTE和CAG对心外畸形诊断符合率分别为95.5%、72.7%和95.5%,MSCT、CAG诊断符合率明显高于TTE（P=0.004,P〈0.05）。结论：64层CT能客观清晰地显示CHD的病理解剖形态,对心脏大血管连接部及大血管畸形的诊断明显优于TTE,在CHD的无创性检查中具有较高的诊断价值。

64-slice Spiral CT in the Diagnosis of Congenital Heart Disease

Objective:To discuss the value of three-dimensional reconstruction post-processing techniques with contrast enhanced 64-slice spiral CT (MSCT) scanning in the diagnosis of congenital heart disease (CHD).Methods:The pre-surgical imaging materials including CT,trans-thoracic echocardiogram (TTE) and cine-angiocardiogram (CAG) of 52 patients with CHD confirmed by surgery were retrospectively analyzed.Results:Of the 52 patients,A total of 142 cardiac anomalies were found by surgery.There were 54 intra-cardiac a...
