title: [Diagnostic accuracy of pulmonary vessel blood flow assessed by roentgenography--a comparison with haemodynamic data (author's transl)].
abstract: 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%.
