[Possibilities of indirect electroroentgenolymphography of the mediastinum in an experiment].

Using various roentgen contrast preparations and different means of their administration, an optimal contrasting of the mediastinal lymphoapparatus is obtained, when colloid solutions (thorotrast) are injected intraperitoneally. Electroroentgenography with multiple magnification by means of the apparatuses REIS-D and ERGA-02 reveals lymph nodes in the mediastinum of small laboratory animals. Owing to the results of the investigation, it is possible to plan further steps for perfection of the experimental and, later on, clinical lymphography of the mediastinum.
