In this report, the diagnostic value of magnetic resonance imaging (MRI) was compared with that of two-dimensional echocardiography, computed tomography and cardiac catheterization in a patient with pentalogy of Fallot who survived to her fortieth year. The advantages and disadvantages of MRI in diagnosing the present case were as follows: The cardiovascular system, with the exception of atrial septal defect, was evaluated precisely. Collateral vessels were detected using MRI, but impossible with other non-invasive methods. MRI was particularly suitable for imaging the cardiovascular system because of the high contrast between the lower intensity signal of the blood and higher intensity signal of the myocardium and blood vessel walls. Using MRI, data acquisition time was 1.5 min per section. Gated MRI required more time for data acquisition. However, various oblique tomographic projections and very clear static images could be obtained using gated MRI. MRI should be one of the best diagnostic techniques for diagnosing congenital heart disease.
在本报告中，对一名活到40岁的法洛四联症患者，比较了磁共振成像（MRI）与二维超声心动图、计算机断层扫描及心导管检查的诊断价值。MRI在诊断该病例中的优缺点如下：除房间隔缺损外，心血管系统得到了精确评估。通过MRI检测到了侧支血管，而其他非侵入性方法则无法做到。由于血液的低强度信号与心肌和血管壁的高强度信号之间存在高对比度，MRI特别适合对心血管系统进行成像。使用MRI时，每层面的数据采集时间为1.5分钟。门控MRI需要更多的数据采集时间。然而，使用门控MRI可以获得各种斜位断层投影和非常清晰的静态图像。MRI应是诊断先天性心脏病的最佳诊断技术之一。
