[Value of transrectal and transvaginal ultrasonic tomography using an electronic linear scanner in staging bladder tumors].

The results of sonographic studies of 48 patients with carcinoma of the urinary bladder are discussed. The value of longitudinal intracavitary sonography for assessment of the local extent of malignant tumors of the bladder was studied. This method is thought to be extremely useful when tumors are localized on the neck, base and front wall of the bladder, whereas transabdominal sonography gives valuable diagnostic information if the lateral and back walls are involved.

[Double contrast examination of the pericardial cavity in a case of exsudative pericarditis (author's transl)].

1)Radiographic examinations of the pericardial cavity by double contrast technique yield good information about the pericardial layer itself, the pericardial cavity and its contents. -- 2) Pericardial puncture and fluid aspiration and subsequent creation of a pneumopericardium with installation of water soluble contrast material are important diagnostic tools and have an important therapeutic effect as well. -- 3) For an appropriate examination 300--400 ml gas (oxygen in inflammatory, room air in carcinomatous conditions) and 5--8 ml of 60% water soluble contrast material (0.
