Clinical Study of 3D CT angiography in complex congenital heart disease / 医疗卫生装备

ABSTRACT

Objective To evaluate the application of MSCT angiography in complex congenital heart disease.Methods Images of patient with complex congenital heart disease were acquired by MSCT with dedicated parameters.Target vas in ROI was identified with plain scanning and then contrast scanning were followed.The preset CT value of the target vas was 160 Hu.The computer would expose automatically when the contrast agent reached the value.Results The target vas was scanned continuously when the contrast agent reached the preset value after "bonus injection" of the vain.Then the acquired data were processed into a clear 3D image of cardiac vas.Conclusion 3D CT angiography is a safe,effective and noninvasive imaging modality for complex congenital heart disease.
