摘　　要：目的探讨多层螺旋CT肺血管成像对先天性心脏病合并肺动脉高压的诊断价值。方法对56例先天性心脏病合并肺动脉高压病例行多层螺旋CT肺动脉成像检查,图像采用1.0mm层厚、0.7mm层间距进行重建,CTPA后处理采用容积再现(VRT)、最大密度投影(MIP)和多平面重建(MPR),对重建的图像进行对比分析。结果 56例病例中,实验组41例病变肺动脉重建图像改变与对照组15例相比较具有明显差异(P<0.001)。结论多层螺旋CT肺血管成像具有安全、快速、无创优点,可以比较准确的诊断先天性心脏病合并肺动脉高压肺血管的病变程度。Objective To evaluate the diagnoses value of pulmonary vascular angiography with spiral CT in patients with congenital heart disease complicated by pulmonary hypertension.Methods Analyze the rebuild images of pulmonary vascular angiography with spiral CT in 56 patients with congenital heart disease complicated by pulmonary hypertension.The images are rebuilding with the thickness of 1.0mm,and 0.7mm between each lamella.The images are evaluated with VRT MIP and MPR.Results There is a significant difference between the experiment group and the control group in the rebuild images of pulmonary vascular angiography with spiral CT （P0.001）.Conclusion The pulmonary vascular angiography with spiral CT is a helpful method in diagnosing the lesions of the patients with congenital heart disease complicated by pulmonary hypertension.
