中低场磁共振成像诊断法乐氏四联症(附九例报告)

Magnetic Resonance Imaging Diagnosis of the Tetralogy of Fallot (nine case report)

作者采用中低场磁共振成像新技术检查了9例法乐氏四联症患者,并与超声心动图和心血管造影结果相比较。结果表明,在定性和定量诊断方面,磁共振成像好于超声心动图,而和心血管造影相同,在显示心内形态结构方面,磁共振成像好于其他两种方法。磁共振成像能显示法乐氏四联症者的全部病理改变,为外科术前诊断提供更多有价值的信息,将三种方法相结合使用能明显提高临床诊断水平。

Nine patients with Tetralogy of Fallot were examined by magnetic resonance imaging, and MR findings were compared with that of Doppler Echocardio-grophy (DE) and Angio cadiogrophy (ACG). The results demonstrated that the level of diagnoses with MRI was higher than that of the DE, and equal to the ACG at the accuracy and quantitative diagnosis. MRI can more clearly delineated the morphological structures of cardiovascular which Tetralogy of Fallot. It will provide more worthful information for the diagnoses before surgical operation by MRI examined. Obviously, the diagnostic accuracy rates of Tetralogy of Fallot can be much improved if a work-up MRI with DE and ACG is engaged.
