[Modern differentiation possibilities of angiocardiography in childhood].

1. Angiocardiography plays an irreplaceable method of investigation in the diagnosis of cardiac diseases in infancy and childhood. In many cases it is the "crown" of the diagnosis. 2. Cine-angiocardiography is indispensable in paediatric cardiology. In infancy, in rapid heart rates and in complicated malformations of the heart, only a movie film (35 mm) can register completely all the anatomic and haemodynamic details. 3. In certain cases the serial angiocardiography is also necessary in childhood. Today two methods of radiography can be made use of: the direct recording by means of rapid film changers on full size X-ray films and the indirect method on 70- or 100-mm size films. 4. According to our experience, the serial angiocardiography recordings on 70-mm size films have more advantages than the usual full size films (35 x 35 cm). In the interpretation of the 70-mm-size films there is no loss of information, and the radiators dose is 1/10 lower than in AOT-size.
