The article reports on an examination of the diagnostic accuracy in assessing the pulmonary vessel blood flow via x-ray films of the thorax in 323 children by means of a comparison with the haemodynamic data of four examiners, on the basis of a Yes/No (True/False) decision. Overall accuracy in the total group of examined children--depending on the experience of the examiners--was 60 to 66%; in children below 2 years of age, it was 63-69%, and in children over 2 years old it was 59-65%. In a Left-Right Shunt smaller than 35%, accuracy was between 33 and 63%; if the Left-Right Shunt was greater than 57%, it was 81-97%. Diagnosis of reduced pulmonary blood flow proved more difficult than of an enhanced flow. Sensitivity of the examination method was 53-71%, whereas its specificity was 57-70%.
本文报道了一项针对323名儿童通过胸部X光片评估肺血管血流诊断准确性的研究，该研究通过与四名检查者的血流动力学数据进行比较，并基于“是/否”（“真/假”）判断。根据检查者的经验，在所有接受检查的儿童组中，总体准确率为60%至66%；在2岁以下儿童中，准确率为63%至69%，在2岁以上儿童中，准确率为59%至65%。在左向右分流小于35%的情况下，准确率在33%至63%之间；如果左向右分流大于57%，准确率则为81%至97%。事实证明，诊断肺血流减少比诊断肺血流增加更为困难。该检查方法的敏感性为53%至71%，而其特异性为57%至70%。
